+
+You can use an external service for validating a pipeline before it's created.
+
+CAUTION: **Warning:**
+This is an experimental feature and subject to change without notice.
+
+## Usage
+
+GitLab will send a POST request to the external service URL with the pipeline
+data as payload. GitLab will then invalidate the pipeline based on the response
+code. If there's an error or the request times out, the pipeline will not be
+invalidated.
+
+Response Code Legend:
+
+- `200` - Accepted
+- `4xx` - Not Accepted
+- Other Codes - Accepted and Logged
+
+## Configuration
+
+Set the `EXTERNAL_VALIDATION_SERVICE_URL` to the external service url.

+## Direct Git access in GitLab Rails
+
+Also known as "the Rugged patches".
+
+### History
+
+Before Gitaly existed, the things that are now Gitaly clients used to
+access Git repositories directly. Either on a local disk in the case of
+e.g. a single-machine Omnibus GitLab installation, or via NFS in the
+case of a horizontally scaled GitLab installation.
+
+Besides running plain `git` commands, in GitLab Rails we also used to
+use a Ruby gem (library) called
+[Rugged](https://github.com/libgit2/rugged). Rugged is a wrapper around
+[libgit2](https://libgit2.org/), a stand-alone implementation of Git in
+the form of a C library.
+
+Over time it has become clear to use that Rugged, and particularly
+Rugged in combination with the [Unicorn](https://bogomips.org/unicorn/)
+web server, is extremely efficient. Because libgit2 is a *library* and
+not an external process, there was very little overhead between GitLab
+application code that tried to look up data in Git repositories, and the
+Git implementation itself.
+
+Because Rugged+Unicorn was so efficient, GitLab's application code ended
+up with lots of duplicate Git object lookups (like looking up the
+`master` commmit a dozen times in one request). We could write
+inefficient code without being punished for it.
+
+When we migrated these Git lookups to Gitaly calls, we were suddenly
+getting a much higher fixed cost per Git lookup. Even when Gitaly is
+able to re-use an already-running `git` process to look up e.g. a commit
+you still have the cost of a network roundtrip to Gitaly, and within
+Gitaly a write/read roundtrip on the Unix pipes that connect Gitaly to
+the `git` process.
+
+Using GitLab.com performance as our yardstick, we pushed down the number
+of Gitaly calls per request until the loss of Rugged's efficiency was no
+longer felt. It also helped that we run Gitaly itself directly on the
+Git file severs, rather than via NFS mounts: this gave us a speed boost
+that counteracted the negative effect of not using Rugged anymore.
+
+Unfortunately, some *other* deployments of GitLab could not ditch NFS
+like we did on GitLab.com and they got the worst of both worlds: the
+slowness of NFS and the increased inherent overhead of Gitaly.
+
+As a performance band-aid for these stuck-on-NFS deployments, we
+re-introduced some of the old Rugged code that got deleted from
+GitLab Rails during the Gitaly migration project. These pieces of
+re-introduced code are informally referred to as "the Rugged patches".
+
+### Activation of direct Git access in GitLab Rails
+
+The Ruby methods that perform direct Git access are hidden behind [feature
+flags](../../development/gitaly.md#legacy-rugged-code). These feature
+flags are off by default. It is not good if you need to know about
+feature flags to get the best performance so in a second iteration, we
+added an automatic mechanism that will enable direct Git access.
+
+When GitLab Rails calls a function that has a Rugged patch it performs
+two checks. The result of both of these checks is cached.
+
+1. Is the feature flag for this patch set in the database? If so, do
+    what the feature flag says.
+1. If the feature flag is not set (i.e. neither true nor false), try to
+    see if we can access filesystem underneath the Gitaly server
+    directly. If so, use the Rugged patch.
+
+To see if GitLab  Rails can access the repo filesystem directly, we use
+the following heuristic:
+
+- Gitaly ensures that the filesystem has a metadata file in its root
+  with a UUID in it.
+- Gitaly reports this UUID to GitLab Rails via the `ServerInfo` RPC.
+- GitLab Rails tries to read the metadata file directly. If it exists,
+  and if the UUID's match, assume we have direct access.
+
+Because of the way the UUID check works, and because Omnibus GitLab will
+fill in the correct repository paths in the GitLab Rails config file
+`config/gitlab.yml`, **direct Git access in GitLab Rails is on by default in
+Omnibus**.
+
+### Plans to remove direct Git access in GitLab Rails
+
+For the sake of removing complexity it is desirable that we get rid of
+direct Git access in GitLab Rails. For as long as some GitLab installations are stuck
+with Git repositories on slow NFS, however, we cannot just remove them.
+
+There are two prongs to our efforts to remove direct Git access in GitLab Rails:
+
+1. Reduce the number of (inefficient) Gitaly queries made by
+   GitLab Rails.
+1. Persuade everybody who runs a Highly Available / horizontally scaled
+   GitLab installation to move off of NFS.
+
+The second prong is the only real solution. For this we need [Gitaly
+HA](https://gitlab.com/groups/gitlab-org/-/epics?scope=all&utf8=%E2%9C%93&state=opened&label_name[]=Gitaly%20HA),
+which is still under development as of December 2019.

 ## Troubleshooting Gitaly
 
+### Checking versions when using standalone Gitaly nodes
+
+When using standalone Gitaly nodes, you must make sure they are the same version
+as GitLab to ensure full compatibility. Check **Admin Area > Gitaly Servers** on
+your GitLab instance and confirm all Gitaly Servers are `Up to date`.

+
+We need to manage the following secrets and make them match across hosts:

+
+## Snippets content size limit
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/31133) in GitLab 12.6.
+
+You can set a content size max limit in snippets. This limit can prevent
+abuses of the feature. The default content size limit is **52428800 Bytes** (50MB).
+
+### How does it work?
+
+The content size limit will be applied when a snippet is created or
+updated. Nevertheless, in order not to break any existing snippet,
+the limit will only be enforced in stored snippets when the content
+is updated.
+
+### Snippets size limit configuration
+
+This setting is not available through the [Admin Area settings](../../user/admin_area/settings/index.md).
+In order to configure this setting, use either the Rails console
+or the [Application settings API](../../api/settings.md).
+
+NOTE: **IMPORTANT:**
+The value of the limit **must** be in Bytes.
+
+#### Through the Rails console
+
+The steps to configure this setting through the Rails console are:
+
+1. Start the Rails console:
+
+   ```bash
+   # For Omnibus installations
+   sudo gitlab-rails console
+
+   # For installations from source
+   sudo -u git -H bundle exec rails console production
+   ```
+
+1. Update the snippets maximum file size:
+
+   ```ruby
+   ApplicationSetting.first.update!(snippet_size_limit: 50.megabytes)
+   ```
+
+To retrieve the current value, start the Rails console and run:
+
+  ```ruby
+  Gitlab::CurrentSettings.snippet_size_limit
+  ```
+
+#### Through the API
+
+The process to set the snippets size limit through the Application Settings API is
+exactly the same as you would do to [update any other setting](../../api/settings.md#change-application-settings).
+
+```bash
+curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" https://gitlab.example.com/api/v4/application/settings?snippet_size_limit=52428800
+```
+
+You can also use the API to [retrieve the current value](../../api/settings.md#get-current-application-settings).
+
+```bash
+curl --header "PRIVATE-TOKEN: <your_access_token>" https://gitlab.example.com/api/v4/application/settings
+```

 TIP: **Tip:** In support, our general approach to reconfiguring timeouts (applies also to the HTTP stack as well) is that it's acceptable to do it temporarily as a workaround. If it makes GitLab usable for the customer, then it buys time to understand the problem more completely, implement a hot fix, or make some other change that addresses the root cause. Generally, the timeouts should be put back to reasonable defaults once the root cause is resolved.

+### Keyset-based pagination
+
+Keyset-pagination allows for more efficient retrieval of pages and - in contrast to offset-based pagination - runtime
+is independent of the size of the collection.
+
+This method is controlled by the following parameters:
+
+| Parameter    | Description                            |
+| ------------ | -------------------------------------- |
+| `pagination` | `keyset` (to enable keyset pagination) |
+| `per_page`   | Number of items to list per page (default: `20`, max: `100`) |
+
+In the example below, we list 50 [projects](projects.md) per page, ordered by `id` ascending.
+
+```bash
+curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects?pagination=keyset&per_page=50&order_by=id&sort=asc"
+```
+
+The response header includes a link to the next page. For example:
+
+```
+HTTP/1.1 200 OK
+...
+Link: <https://gitlab.example.com/api/v4/projects?pagination=keyset&per_page=50&order_by=id&sort=asc&id_after=42>; rel="next"
+Status: 200 OK
+...
+```
+
+The link to the next page contains an additional filter `id_after=42` which excludes records we have retrieved already.
+Note the type of filter depends on the `order_by` option used and we may have more than one additional filter.
+
+The `Link` header is absent when the end of the collection has been reached and there are no additional records to retrieve.
+
+We recommend using only the given link to retrieve the next page instead of building your own URL. Apart from the headers shown,
+we don't expose additional pagination headers.
+
+Keyset-based pagination is only supported for selected resources and ordering options:
+
+| Resource                  | Order                      |
+| ------------------------- | -------------------------- |

+# Getting started with GitLab GraphQL API
+
+This guide demonstrates basic usage of GitLab's GraphQL API.
+
+See the [GraphQL API StyleGuide](../../development/api_graphql_styleguide.md) for implementation details
+aimed at developers who wish to work on developing the API itself.
+
+## Running examples
+
+The examples documented here can be run using:
+
+- The command line.
+- GraphiQL.
+
+### Command line
+
+You can run GraphQL queries in a `curl` request on the command line on your local machine.
+A GraphQL request can be made as a `POST` request to `/api/graphql` with the query as the payload.
+You can authorize your request by generating a [personal access token](../../user/profile/personal_access_tokens.md)
+to use as a bearer token.
+
+Example:
+

+```
+
+### GraphiQL
+
+GraphiQL (pronounced “graphical”) allows you to run queries directly against the server endpoint
+with syntax highlighting and autocomplete. It also allows you to explore the schema and types.
+
+The examples below:
+
+- Can be run directly against GitLab 11.0 or later, though some of the types and fields
+may not be supported in older versions.
+- Will work against GitLab.com without any further setup. Make sure you are signed in and
+navigate to the [GraphiQL Explorer](https://www.gitlab.com/-/graphql-explorer).
+
+If you want to run the queries locally, or on a self-managed instance,
+you will need to either:
+
+- Create the `gitlab-org` group with a project called `graphql-sandbox` under it. Create
+several issues within the project.
+- Edit the queries to replace `gitlab-org/graphql-sandbox` with your own group and project.
+
+Please refer to [running GraphiQL](index.md#graphiql) for more information.
+
+NOTE: **Note:**
+If you are running GitLab 11.0 to 12.0, enable the `graphql`
+[feature flag](../features.md#set-or-create-a-feature).
+
+## Queries and mutations
+
+The GitLab GraphQL API can be used to perform:
+
+- Queries for data retrieval.
+- [Mutations](#mutations) for creating, updating, and deleting data.
+
+NOTE: **Note:**
+In the GitLab GraphQL API, `id` generally refers to a global ID,
+which is an object identifier in the format of `gid://gitlab/Issue/123`.
+
+[GitLab's GraphQL Schema](reference/index.md) outlines which objects and fields are
+available for clients to query and their corresponding data types.
+
+Example: Get only the names of all the projects the currently logged in user can access (up to a limit, more on that later)
+in the group `gitlab-org`.
+
+```graphql
+query {
+  group(fullPath: "gitlab-org") {
+    id
+    name
+    projects {
+      nodes {
+        name
+      }
+    }
+  }
+}
+```
+
+Example: Get a specific project and the title of Issue #2.
+
+```graphql
+query {
+  project(fullPath: "gitlab-org/graphql-sandbox") {
+    name
+    issue(iid: "2") {
+      title
+    }
+  }
+}
+```
+
+### Graph traversal
+
+When retrieving child nodes use:
+
+- the `edges { node { } }` syntax.
+- the short form `nodes { }` syntax.
+
+Underneath it all is a graph we are traversing, hence the name GraphQL.
+
+Example: Get a project (only its name) and the titles of all its issues.
+
+```graphql
+query {
+  project(fullPath: "gitlab-org/graphql-sandbox") {
+    name
+    issues {
+      nodes {
+        title
+        description
+      }
+    }
+  }
+}
+```
+
+More about queries:
+[GraphQL docs](https://graphql.org/learn/queries/)
+
+### Authorization
+
+Authorization uses the same engine as the GitLab application (and GitLab.com). So if you've signed in to GitLab
+and use GraphiQL, all queries will be performed as you, the signed in user. For more information, see the
+[GitLab API documentation](../README.md#authentication).
+
+### Mutations
+
+Mutations make changes to data. We can update, delete, or create new records. Mutations
+generally use InputTypes and variables, neither of which appear here.
+
+Mutations have:
+
+- Inputs. For example, arguments, such as which emoji you'd like to award,
+and to which object.
+- Return statements. That is, what you'd like to get back when it's successful.
+- Errors. Always ask for what went wrong, just in case.
+
+#### Creation mutations
+
+Example: Let's have some tea - add a `:tea:` reaction emoji to an issue.
+
+```graphql
+mutation {
+  addAwardEmoji(input: { awardableId: "gid://gitlab/Issue/27039960",
+      name: "tea"
+    }) {
+    awardEmoji {
+      name
+      description
+      unicode
+      emoji
+      unicodeVersion
+      user {
+        name
+      }
+    }
+    errors
+  }
+}
+```
+
+Example: Add a comment to the issue (we're using the ID of the `GitLab.com` issue - but
+if you're using a local instance, you'll need to get the ID of an issue you can write to).
+
+```graphql
+mutation {
+  createNote(input: { noteableId: "gid://gitlab/Issue/27039960",
+      body: "*sips tea*"
+    }) {
+    note {
+      id
+      body
+      discussion {
+        id
+      }
+    }
+    errors
+  }
+}
+```
+
+#### Update mutations
+
+When you see the result `id` of the note you created - take a note of it. Now let's edit it to sip faster!
+
+```graphql
+mutation {
+  updateNote(input: { id: "gid://gitlab/Note/<note id>",
+      body: "*SIPS TEA*"
+    }) {
+    note {
+      id
+      body
+    }
+    errors
+  }
+}
+```
+
+#### Deletion mutations
+
+Let's delete the comment, since our tea is all gone.
+
+```graphql
+mutation {
+  destroyNote(input: { id: "gid://gitlab/Note/<note id>" }) {
+    note {
+      id
+      body
+    }
+    errors
+  }
+}
+```
+
+You should get something like the following output:
+
+```json
+{
+  "data": {
+    "destroyNote": {
+      "errors": [],
+      "note": null
+    }
+  }
+}
+```
+
+We've asked for the note details, but it doesn't exist anymore, so we get `null`.
+
+More about mutations:
+[GraphQL Docs](https://graphql.org/learn/queries/#mutations).
+
+### Introspective queries
+
+Clients can query the GraphQL endpoint for information about its own schema.
+by making an [introspective query](https://graphql.org/learn/introspection/).
+
+It is through an introspection query that the [GraphiQL Query Explorer](https://gitlab.com/-/graphql-explorer)
+gets all of its knowledge about our GraphQL schema to do autocompletion and provide
+its interactive `Docs` tab.
+
+Example: Get all the type names in the schema.
+
+```graphql
+{
+  __schema {
+    types {
+      name
+    }
+  }
+}
+```
+
+Example: Get all the fields associated with Issue.
+`kind` tells us the enum value for the type, like `OBJECT`, `SCALAR` or `INTERFACE`.
+
+```graphql
+query IssueTypes {
+  __type(name: "Issue") {
+    kind
+    name
+    fields {
+      name
+      description
+      type {
+        name
+      }
+    }
+  }
+}
+```
+
+More about introspection:
+[GraphQL docs](https://graphql.org/learn/introspection/)
+
+## Sorting
+
+Some of GitLab's GraphQL endpoints allow you to specify how you'd like a collection of
+objects to be sorted. You can only sort by what the schema allows you to.
+
+Example: Issues can be sorted by creation date:
+
+```graphql
+query {
+  project(fullPath: "gitlab-org/graphql-sandbox") {
+   name
+    issues(sort: created_asc) {
+      nodes {
+        title
+        createdAt
+      }
+    }
+  }
+}
+```
+
+## Pagination
+
+Pagination is a way of only asking for a subset of the records (say, the first 10).
+If we want more of them, we can make another request for the next 10 from the server
+(in the form of something like "please give me the next 10 records").
+
+By default, GitLab's GraphQL API will return only the first 100 records of any collection.
+This can be changed by using `first` or `last` arguments. Both arguments take a value,
+so `first: 10` will return the first 10 records, and `last: 10` the last 10 records.
+
+Example: Retrieve only the first 2 issues (slicing). The `cursor` field gives us a position from which
+we can retrieve further records relative to that one.
+
+```graphql
+query {
+  project(fullPath: "gitlab-org/graphql-sandbox") {
+    name
+    issues(first: 2) {
+      edges {
+        node {
+          title
+        }
+      }
+      pageInfo {
+        endCursor
+        hasNextPage
+      }
+    }
+  }
+}
+```
+
+Example: Retrieve the next 3. (The cursor value
+`eyJpZCI6IjI3MDM4OTMzIiwiY3JlYXRlZF9hdCI6IjIwMTktMTEtMTQgMDU6NTY6NDQgVVRDIn0`
+could be different, but it's the `cursor` value returned for the second issue returned above.)
+
+```graphql
+query {
+  project(fullPath: "gitlab-org/graphql-sandbox") {
+    name
+    issues(first: 3, after: "eyJpZCI6IjI3MDM4OTMzIiwiY3JlYXRlZF9hdCI6IjIwMTktMTEtMTQgMDU6NTY6NDQgVVRDIn0") {
+      edges {
+        node {
+          title
+        }
+        cursor
+      }
+      pageInfo {
+        endCursor
+        hasNextPage
+      }
+    }
+  }
+}
+```

+  Artifacts are files generated by a job which are stored and uploaded, and can then
+  be fetched and used by jobs in later stages of the **same pipeline**. This data
+  will not be available in different pipelines, but is available to be downloaded

+

+
+If you are deploying to a [Kubernetes cluster](../user/project/clusters/index.md)

+`production` Kubernetes namespace.

+NOTE: **Note:**
+Kubernetes configuration is not supported for Kubernetes clusters

 # GraphQL API
 
+## How GitLab implements GraphQL
+
+We use the [graphql-ruby gem](https://graphql-ruby.org/) written by [Robert Mosolgo](https://github.com/rmosolgo/).
+
+All GraphQL queries are directed to a single endpoint
+([`app/controllers/graphql_controller.rb#execute`](https://gitlab.com/gitlab-org/gitlab/blob/master/app%2Fcontrollers%2Fgraphql_controller.rb)),
+which is exposed as an API endpoint at `/api/graphql`.

 ## Types

+```ruby

+markdown_field :title_html, null: true
+field :description, GraphQL::STRING_TYPE, null: true
+markdown_field :description_html, null: true
+```
+
+We give each type a name (in this case `Issue`).
+
+The `iid`, `title` and `description` are _scalar_ GraphQL types.
+`iid` is a `GraphQL::ID_TYPE`, a special string type that signifies a unique ID.

+## Notes about Query flow and GraphQL infrastructure
+
+GitLab's GraphQL infrastructure can be found in `lib/gitlab/graphql`.
+
+[Instrumentation](https://graphql-ruby.org/queries/instrumentation.html) is functionality
+that wraps around a query being executed. It is implemented as a module that uses the `Instrumentation` class.
+
+Example: `Present`
+
+```ruby
+module Present
+  #... some code above...
+
+  def self.use(schema_definition)
+    schema_definition.instrument(:field, Instrumentation.new)
+  end
+end
+```
+
+A [Query Analyzer](https://graphql-ruby.org/queries/analysis.html#analyzer-api) contains a series
+of callbacks to validate queries before they are executed. Each field can pass through
+the analyzer, and the final value is also available to you.
+
+[Multiplex queries](https://graphql-ruby.org/queries/multiplex.html) enable
+multiple queries to be sent in a single request. This reduces the number of requests sent to the server.
+(there are custom Multiplex Query Analyzers and Multiplex Instrumentation provided by graphql-ruby).
+
+### Query limits
+
+Queries and mutations are limited by depth, complexity, and recursion
+to protect server resources from overly ambitious or malicious queries.
+These values can be set as defaults and overridden in specific queries as needed.
+The complexity values can be set per object as well, and the final query complexity is
+evaluated based on how many objects are being returned. This is useful
+for objects that are expensive (e.g. requiring Gitaly calls).
+
+For example, a conditional complexity method in a resolver:
+
+```ruby
+def self.resolver_complexity(args, child_complexity:)
+  complexity = super
+  complexity += 2 if args[:labelName]
+
+  complexity
+end
+```
+
+More about complexity:

 ## Documentation and Schema
 
+Our schema is located at `app/graphql/gitlab_schema.rb`.
+See the [schema reference](../api/graphql/reference/index.md) for details.

+# Cycle Analytics development guide
+
+Cycle analytics calculates the time between two arbitrary events recorded on domain objects and provides aggregated statistics about the duration.
+
+## Stage
+
+During development, events occur that move issues and merge requests through different stages of progress until they are considered finished. These stages can be expressed with the `Stage` model.
+
+Example stage:
+
+- Name: Development
+- Start event: Issue created
+- End event: Issue first mentioned in commit
+- Parent: `Group: gitlab-org`
+
+### Events
+
+Events are the smallest building blocks of the cycle analytics feature. A stage consists of two events:
+
+- Start
+- End
+
+These events play a key role in the duration calculation.
+
+Formula: `duration = end_event_time - start_event_time`
+
+To make the duration calculation flexible, each `Event` is implemented as a separate class. They're responsible for defining a timestamp expression that will be used in the calculation query.
+
+#### Implementing an `Event` class
+
+There are a few methods that are required to be implemented, the `StageEvent` base class describes them in great detail. The most important ones are:
+
+- `object_type`
+- `timestamp_projection`
+
+The `object_type` method defines which domain object will be queried for the calculation. Currently two models are allowed:
+
+- `Issue`
+- `MergeRequest`
+
+For the duration calculation the `timestamp_projection` method will be used.
+
+```ruby
+def timestamp_projection
+  # your timestamp expression comes here
+end
+
+# event will use the issue creation time in the duration calculation
+def timestamp_projection
+  Issue.arel_table[:created_at]
+end
+```
+
+NOTE: **Note:**
+More complex expressions are also possible (e.g. using `COALESCE`). Look at the existing event classes for examples.
+
+In some cases, defining the `timestamp_projection` method is not enough. The calculation query should know which table contains the timestamp expression. Each `Event` class is responsible for making modifications to the calculation query to make the `timestamp_projection` work. This usually means joining an additional table.
+
+Example for joining the `issue_metrics` table and using the `first_mentioned_in_commit_at` column as the timestamp expression:
+
+```ruby
+def object_type
+  Issue
+end
+
+def timestamp_projection
+  IssueMetrics.arel_table[:first_mentioned_in_commit_at]
+end
+
+def apply_query_customization(query)
+  # in this case the query attribute will be based on the Issue model: `Issue.where(...)`
+  query.joins(:metrics)
+end
+```
+
+### Validating start and end events
+
+Some start/end event pairs are not "compatible" with each other. For example:
+
+- "Issue created" to "Merge Request created": The event classes are defined on different  domain models, the `object_type` method is different.
+- "Issue closed" to "Issue created": Issue must be created first before it can be  closed.
+- "Issue closed" to "Issue closed": Duration is always 0.
+
+The `StageEvents` module describes the allowed `start_event` and `end_event` pairings (`PAIRING_RULES` constant). If a new event is added, it needs to be registered in this module.
+To add a new event:
+
+1. Add an entry in `ENUM_MAPPING` with a unique number, it'll be used in the `Stage` model as `enum`.
+1. Define which events are compatible with the event in the `PAIRING_RULES` hash.
+
+Supported start/end event pairings:
+
+```mermaid
+graph LR;
+  IssueCreated --> IssueClosed;
+  IssueCreated --> IssueFirstAddedToBoard;
+  IssueCreated --> IssueFirstAssociatedWithMilestone;
+  IssueCreated --> IssueFirstMentionedInCommit;
+  IssueCreated --> IssueLastEdited;

+
+### Parent
+
+Teams and organizations might define their own way of building software, thus stages can be completely different. For each stage, a parent object needs to be defined.
+
+Currently supported parents:
+
+- `Project`
+- `Group`
+
+#### How parent relationship it work
+
+1. User navigates to the cycle analytics page.
+1. User selects a group.
+1. Backend loads the defined stages for the selected group.
+1. Additions and modifications to the stages will be persisted within the selected group only.
+
+### Default stages
+
+The [original implementation](https://gitlab.com/gitlab-org/gitlab/issues/847) of cycle analytics defined 7 stages. These stages are always available for each parent, however altering these stages is not possible.
+
+To make things efficient and reduce the number of records created, the default stages are expressed as in-memory objects (not persisted). When the user creates a custom stage for the first time, all the stages will be persisted. This behaviour is implemented in the cycle analytics service objects.
+
+The reason for this was that we'd like to add the abilities to hide and order stages later on.
+
+## Data Collector
+
+`DataCollector` is the central point where the data will be queried from the database. The class always operates on a single stage and consists of the following components:
+
+- `BaseQueryBuilder`:
+  - Responsible for composing the initial query.
+  - Deals with `Stage` specific configuration: events and their query customizations.
+  - Parameters coming from the UI: date ranges.
+- `Median`: Calculates the median duration for a stage using the query from  `BaseQueryBuilder`.
+- `RecordsFetcher`: Loads relevant records for a stage using the query from  `BaseQueryBuilder` and specific `Finder` classes to apply visibility rules.
+- `DataForDurationChart`: Loads calculated durations with the finish time (end event timestamp) for the scatterplot chart.
+
+For a new calculation or a query, implement it as a new method call in the `DataCollector` class.
+
+## Database query
+
+Structure of the database query:
+
+```sql
+SELECT (customized by: Median or RecordsFetcher or DataForDurationChart)
+FROM OBJECT_TYPE (Issue or MergeRequest)
+INNER JOIN (several JOIN statements, depending on the events)
+WHERE
+  (Filter by the PARENT model, example: filter Issues from Project A)
+  (Date range filter based on the OBJECT_TYPE.created_at)
+  (Check if the START_EVENT is earlier than END_EVENT, preventing negative duration)
+```
+
+Structure of the `SELECT` statement for `Median`:
+
+```sql
+SELECT (calculate median from START_EVENT_TIME-END_EVENT_TIME)
+```
+
+Structure of the `SELECT` statement for `DataForDurationChart`:
+
+```sql
+SELECT (START_EVENT_TIME-END_EVENT_TIME) as duration, END_EVENT.timestamp
+```
+
+## High-level overview
+
+- Rails Controller (`Analytics::CycleAnalytics` module): Cycle analytics exposes its data via JSON endpoints, implemented within the `analytics` workspace. Configuring the stages are also implements JSON endpoints (CRUD).
+- Services (`Analytics::CycleAnalytics` module): All `Stage` related actions will be delegated to respective service objects.
+- Models (`Analytics::CycleAnalytics` module): Models are used to persist the `Stage` objects `ProjectStage` and `GroupStage`.
+- Feature classes (`Gitlab::Analytics::CycleAnalytics` module):
+  - Responsible for composing queries and define feature specific busines logic.
+  - `DataCollector`, `Event`, `StageEvents`, etc.
+
+## Testing
+
+Since we have a lots of events and possible pairings, testing each pairing is not possible. The rule is to have at least one test case using an `Event` class.
+
+Writing a test case for a stage using a new `Event` can be challenging since data must be created for both events. To make this a bit simpler, each test case must be implemented in the `data_collector_spec.rb` where the stage is tested through the `DataCollector`. Each test case will be turned into multiple tests, covering the following cases:
+
+- Different parents: `Group` or `Project`
+- Different calculations: `Median`, `RecordsFetcher` or `DataForDurationChart`

+# Database query comments with Marginalia
+
+The [Marginalia gem](https://github.com/basecamp/marginalia) is used to add
+query comments containing application related context information to PostgreSQL
+queries generated by ActiveRecord.
+
+It is very useful for tracing problematic queries back to the application source.
+
+An engineer during an on-call incident will have the full context of a query
+and its application source from the comments.
+
+## Metadata information in comments
+
+Queries generated from **Rails** include the following metadata in comments:
+
+- `application`
+- `controller`
+- `action`
+- `correlation_id`
+- `line`
+
+Queries generated from **Sidekiq** workers will include the following metadata
+in comments:
+
+- `application`
+- `jid`
+- `job_class`
+- `correlation_id`
+- `line`
+
+Examples of queries with comments as observed in `development.log`:
+
+1. Rails:
+
+   ```sql
+   SELECT "project_features".* FROM "project_features" WHERE "project_features"."project_id" = $1 LIMIT $2 [["project_id", 5], ["LIMIT", 1]] /*application:web,controller:jobs,action:trace,correlation_id:rYF4mey9CH3,line:/app/policies/project_policy.rb:504:in `feature_available?'*/
+   ```
+
+1. Sidekiq:
+
+   ```sql
+   SELECT "ci_pipelines".* FROM "ci_pipelines" WHERE "ci_pipelines"."id" = $1 LIMIT $2 [["id", 64], ["LIMIT", 1]] /*application:sidekiq,jid:e7d6668a39a991e323009833,job_class:ExpireJobCacheWorker,correlation_id:rYF4mey9CH3,line:/app/workers/expire_job_cache_worker.rb:14:in `perform'*/
+   ```
+
+## Enable/Disable the feature
+
+Enabling or disabling the feature requires a **restart/SIGHUP** of the Web and
+Sidekiq workers, as the feature flag's state is memoized upon starting up.
+
+The `feature_flag` for this feature is **disabled** by default. You can enable
+or disable it with:
+
+```ruby
+Feature.enable(:marginalia)

+checks a list of known words, listed in the `.markdownlint.json` file in each project,

+In general, product names should follow the exact capitalization of the official names

+- MinIO (needs capital `IO`)
+- NGINX (needs all capitals)
+- runit (needs lowercase `r`)
+
+Additionally, commands, parameters, values, filenames, etc. must be included in backticks.
+For example:
+
+- "Change the `needs` keyword in your `.gitlab.yml`..."
+  - `needs` is a parameter, and `.gitlab.yml` is a file, so both need backticks. Additionally,

-Another possible way is testing queries with mocked GraphQL schema. Read more about this way in [Vue Apollo testing documentation](https://vue-apollo.netlify.com/guide/testing.html#tests-with-mocked-graqhql-schema)
+#### Testing loading state
+
+If we need to test how our component renders when results from the GraphQL API are still loading, we can mock a loading state into respective Apollo queries/mutations:
+
+```javascript
+  function createComponent({
+    loading = false,
+  } = {}) {
+    const $apollo = {
+      queries: {
+        designs: {
+          loading,
+        },
+    };

+    });
+  }
+
+  it('renders loading icon', () => {
+  createComponent({ loading: true });
+
+  expect(wrapper.element).toMatchSnapshot();
+})
+```
+
+#### Testing Apollo components
+
+If we use `ApolloQuery` or `ApolloMutation` in our components, in order to test their functionality we need to add a stub first:
+
+```javascript
+import { ApolloMutation } from 'vue-apollo';
+
+function createComponent(props = {}) {
+  wrapper = shallowMount(MyComponent, {
+    sync: false,
+    propsData: {
+      ...props,
+    },
+    stubs: {
+      ApolloMutation,
+    },
+  });
+}
+```
+
+`ApolloMutation` component exposes `mutate` method via scoped slot. If we want to test this method, we need to add it to mocks:
+
+```javascript
+const mutate = jest.fn(() => Promise.resolve());
+const $apollo = {
+  mutate,
+};
+
+function createComponent(props = {}) {
+  wrapper = shallowMount(MyComponent, {
+    sync: false,
+    propsData: {

+    stubs: {
+      ApolloMutation,
+    },
+    mocks: {
+      $apollo:
+    }
+  });
+}
+```
+
+Then we can check if `mutate` is called with correct variables:
+
+```javascript
+const mutationVariables = {
+  mutation: createNoteMutation,
+  update: expect.anything(),
+  variables: {
+    input: {
+      noteableId: 'noteable-id',
+      body: 'test',
+      discussionId: '0',
+    },
+  },
+};
+
+it('calls mutation on submitting form ', () => {
+  createComponent()

+### Blank target
+
+Use `rel="noopener noreferrer"` whenever your links open in a new window, i.e. `target="_blank"`. This prevents a security vulnerability [documented by JitBit](https://www.jitbit.com/alexblog/256-targetblank---the-most-underestimated-vulnerability-ever/).
+
+```html
+// bad
+<a href="url" target="_blank"></a>
+
+// good
+<a href="url" target="_blank" rel="noopener noreferrer"></a>
+```
+
+### Fake links
+
+**Do not use fake links.** Use a button tag if a link only invokes JavaScript click event handlers, which is more semantic.
+
+```html
+// bad
+<a class="js-do-something" href="#"></a>
+
+// good
+<button class="js-do-something" type="button"></button>
+```

+# GitLab development style guides
+
+See below the relevant style guides, guidelines, linting, and other information for developing GitLab.
+
+## JavaScript style guide
+
+We use `eslint` to enforce our [JavaScript style guides](javascript.md). Our guide is based on
+the excellent [AirBnB](https://github.com/airbnb/javascript) style guide with a few small
+changes.
+
+## SCSS style guide
+
+Our [SCSS conventions](scss.md) which are enforced through [`scss-lint`](https://github.com/brigade/scss-lint).
+
+## HTML style guide
+
+Guidelines for writing [HTML code](html.md) consistent with the rest of the codebase.
+
+## Vue style guide
+
+Guidelines and conventions for Vue code may be found within the [Vue style guide](vue.md).

+
+# JavaScript style guide
+
+We use [Airbnb's JavaScript Style Guide](https://github.com/airbnb/javascript) and it's accompanying
+linter to manage most of our JavaScript style guidelines.
+
+In addition to the style guidelines set by Airbnb, we also have a few specific rules
+listed below.
+
+> **Tip:**
+You can run eslint locally by running `yarn eslint`
+
+## Avoid forEach
+
+Avoid forEach when mutating data. Use `map`, `reduce` or `filter` instead of `forEach`
+when mutating data. This will minimize mutations in functions,
+which aligns with [Airbnb's style guide](https://github.com/airbnb/javascript#testing--for-real).
+
+```javascript
+// bad
+users.forEach((user, index) => {
+  user.id = index;
+});
+
+// good
+const usersWithId = users.map((user, index) => {
+  return Object.assign({}, user, { id: index });
+});
+```
+
+## Limit number of parameters
+
+If your function or method has more than 3 parameters, use an object as a parameter
+instead.
+
+```javascript
+// bad
+function a(p1, p2, p3) {
+  // ...
+};
+
+// good
+function a(p) {
+  // ...
+};
+```
+
+## Avoid classes to handle DOM events
+
+If the only purpose of the class is to bind a DOM event and handle the callback, prefer
+using a function.
+
+```javascript
+// bad
+class myClass {
+  constructor(config) {
+    this.config = config;
+  }
+
+  init() {
+    document.addEventListener('click', () => {});
+  }
+}
+
+// good
+
+const myFunction = () => {
+  document.addEventListener('click', () => {
+    // handle callback here
+  });
+}
+```
+
+## Pass element container to constructor
+
+When your class manipulates the DOM, receive the element container as a parameter.
+This is more maintainable and performant.
+
+```javascript
+// bad
+class a {
+  constructor() {
+    document.querySelector('.b');
+  }
+}
+
+// good
+class a {
+  constructor(options) {
+    options.container.querySelector('.b');
+  }
+}
+```
+
+## Use ParseInt
+
+Use `ParseInt` when converting a numeric string into a number.
+
+```javascript
+// bad
+Number('10')
+
+// good
+parseInt('10', 10);
+```
+
+## CSS Selectors - Use `js-` prefix
+
+If a CSS class is only being used in JavaScript as a reference to the element, prefix
+the class name with `js-`.
+
+```html
+// bad
+<button class="add-user"></button>
+
+// good
+<button class="js-add-user"></button>
+```
+
+## ES Module Syntax
+
+Use ES module syntax to import modules:
+
+```javascript
+// bad
+const SomeClass = require('some_class');
+
+// good
+import SomeClass from 'some_class';
+
+// bad
+module.exports = SomeClass;
+
+// good
+export default SomeClass;
+```
+
+_Note:_ We still use `require` in `scripts/` and `config/` files.
+
+## Absolute vs relative paths for modules
+
+Use relative paths if the module you are importing is less than two levels up.
+
+```javascript
+// bad
+import GitLabStyleGuide from '~/guides/GitLabStyleGuide';
+
+// good
+import GitLabStyleGuide from '../GitLabStyleGuide';
+```
+
+If the module you are importing is two or more levels up, use an absolute path instead:
+
+```javascript
+// bad
+import GitLabStyleGuide from '../../../guides/GitLabStyleGuide';
+
+// good
+import GitLabStyleGuide from '~/GitLabStyleGuide';
+```
+
+Additionally, **do not add to global namespace**.
+
+## Do not use `DOMContentLoaded` in non-page modules
+
+Imported modules should act the same each time they are loaded. `DOMContentLoaded`
+events are only allowed on modules loaded in the `/pages/*` directory because those
+are loaded dynamically with webpack.
+
+## Avoid XSS
+
+Do not use `innerHTML`, `append()` or `html()` to set content. It opens up too many
+vulnerabilities.
+
+## ESLint
+
+ESLint behaviour can be found in our [tooling guide](../tooling.md).
+
+## IIFEs
+
+Avoid using IIFEs (Immediately-Invoked Function Expressions). Although
+we have a lot of examples of files which wrap their contents in IIFEs,
+this is no longer necessary after the transition from Sprockets to webpack.
+Do not use them anymore and feel free to remove them when refactoring legacy code.
+
+## Global namespace
+
+Avoid adding to the global namespace.
+
+```javascript
+// bad
+window.MyClass = class { /* ... */ };
+
+// good
+export default class MyClass { /* ... */ }
+```
+
+## Side effects
+
+### Top-level side effects
+
+Top-level side effects are forbidden in any script which contains `export`:
+
+```javascript
+// bad
+export default class MyClass { /* ... */ }
+
+document.addEventListener("DOMContentLoaded", function(event) {
+  new MyClass();
+}
+```
+
+### Avoid side effects in constructors
+
+Avoid making asynchronous calls, API requests or DOM manipulations in the `constructor`.
+Move them into separate functions instead. This will make tests easier to write and
+avoids violating the [Single Responsibility Principle](https://en.wikipedia.org/wiki/Single_responsibility_principle).
+
+```javascript
+// bad
+class myClass {
+  constructor(config) {
+    this.config = config;
+    axios.get(this.config.endpoint)
+  }
+}
+
+// good
+class myClass {
+  constructor(config) {
+    this.config = config;
+  }
+
+  makeRequest() {
+    axios.get(this.config.endpoint)
+  }
+}
+const instance = new myClass();
+instance.makeRequest();
+```
+
+## Pure Functions and Data Mutation
+
+Strive to write many small pure functions and minimize where mutations occur
+
+  ```javascript
+  // bad
+  const values = {foo: 1};
+
+  function impureFunction(items) {
+    const bar = 1;
+
+    items.foo = items.a * bar + 2;
+
+    return items.a;
+  }
+
+  const c = impureFunction(values);
+
+  // good
+  var values = {foo: 1};
+
+  function pureFunction (foo) {
+    var bar = 1;
+
+    foo = foo * bar + 2;
+
+    return foo;
+  }
+
+  var c = pureFunction(values.foo);
+  ```

+# SCSS style guide
+
+This style guide recommends best practices for SCSS to make styles easy to read,
+easy to maintain, and performant for the end-user.
+
+## Rules
+
+### Utility Classes
+
+As part of the effort for [cleaning up our CSS and moving our components into `gitlab-ui`](https://gitlab.com/groups/gitlab-org/-/epics/950)
+led by the [GitLab UI WG](https://gitlab.com/gitlab-com/www-gitlab-com/merge_requests/20623) we prefer the use of utility classes over adding new CSS. However, complex CSS can be addressed by adding component classes.
+
+#### Where are utility classes defined?
+
+- [Bootstrap's Utility Classes](https://getbootstrap.com/docs/4.3/utilities/)
+- [`common.scss`](https://gitlab.com/gitlab-org/gitlab/blob/master/app/assets/stylesheets/framework/common.scss) (old)
+- [`utilities.scss`](https://gitlab.com/gitlab-org/gitlab/blob/master/app/assets/stylesheets/utilities.scss) (new)
+
+#### Where should I put new utility classes?
+
+New utility classes should be added to [`utilities.scss`](https://gitlab.com/gitlab-org/gitlab/blob/master/app/assets/stylesheets/utilities.scss). Existing classes include:
+
+| Name | Pattern | Example |
+|------|---------|---------|
+| Background color | `.bg-{variant}-{shade}` | `.bg-warning-400` |
+| Text color | `.text-{variant}-{shade}` | `.text-success-500` |
+| Font size | `.text-{size}` | `.text-2` |
+
+- `{variant}` is one of 'primary', 'secondary', 'success', 'warning', 'error'
+- `{shade}` is one of the shades listed on [colors](https://design.gitlab.com/product-foundations/colors/)
+- `{size}` is a number from 1-6 from our [Type scale](https://design.gitlab.com/product-foundations/typography/)
+
+#### When should I create component classes?
+
+We recommend a "utility-first" approach.
+
+1. Start with utility classes.
+1. If composing utility classes into a component class removes code duplication and encapsulates a clear responsibility, do it.
+
+This encourages an organic growth of component classes and prevents the creation of one-off unreusable classes. Also, the kind of classes that emerge from "utility-first" tend to be design-centered (e.g. `.button`, `.alert`, `.card`) rather than domain-centered (e.g. `.security-report-widget`, `.commit-header-icon`).
+
+Examples of component classes that were created using "utility-first" include:
+
+- [`.circle-icon-container`](https://gitlab.com/gitlab-org/gitlab/blob/579fa8b8ec7eb38d40c96521f517c9dab8c3b97a/app/assets/stylesheets/framework/icons.scss#L85)
+- [`.d-flex-center`](https://gitlab.com/gitlab-org/gitlab/blob/900083d89cd6af391d26ab7922b3f64fa2839bef/app/assets/stylesheets/framework/common.scss#L425)
+
+Inspiration:
+
+- <https://tailwindcss.com/docs/utility-first/>
+- <https://tailwindcss.com/docs/extracting-components/>
+
+### Naming
+
+Filenames should use `snake_case`.
+
+CSS classes should use the `lowercase-hyphenated` format rather than
+`snake_case` or `camelCase`.
+
+```scss
+// Bad
+.class_name {
+  color: #fff;
+}
+
+// Bad
+.className {
+  color: #fff;
+}
+
+// Good
+.class-name {
+  color: #fff;
+}
+```
+
+### Formatting
+
+You should always use a space before a brace, braces should be on the same
+line, each property should each get its own line, and there should be a space
+between the property and its value.
+
+```scss
+// Bad
+.container-item {
+  width: 100px; height: 100px;
+  margin-top: 0;
+}
+
+// Bad
+.container-item
+{
+  width: 100px;
+  height: 100px;
+  margin-top: 0;
+}
+
+// Bad
+.container-item{
+  width:100px;
+  height:100px;
+  margin-top:0;
+}
+
+// Good
+.container-item {
+  width: 100px;
+  height: 100px;
+  margin-top: 0;
+}
+```
+
+Note that there is an exception for single-line rulesets, although these are
+not typically recommended.
+
+```scss
+p { margin: 0; padding: 0; }
+```
+
+### Colors
+
+HEX (hexadecimal) colors should use shorthand where possible, and should use
+lower case letters to differentiate between letters and numbers, e.g. `#E3E3E3`
+vs. `#e3e3e3`.
+
+```scss
+// Bad
+p {
+  color: #ffffff;
+}
+
+// Bad
+p {
+  color: #FFFFFF;
+}
+
+// Good
+p {
+  color: #fff;
+}
+```
+
+### Indentation
+
+Indentation should always use two spaces for each indentation level.
+
+```scss
+// Bad, four spaces
+p {
+    color: #f00;
+}
+
+// Good
+p {
+  color: #f00;
+}
+```
+
+### Semicolons
+
+Always include semicolons after every property. When the stylesheets are
+minified, the semicolons will be removed automatically.
+
+```scss
+// Bad
+.container-item {
+  width: 100px;
+  height: 100px
+}
+
+// Good
+.container-item {
+  width: 100px;
+  height: 100px;
+}
+```
+
+### Shorthand
+
+The shorthand form should be used for properties that support it.
+
+```scss
+// Bad
+margin: 10px 15px 10px 15px;
+padding: 10px 10px 10px 10px;
+
+// Good
+margin: 10px 15px;
+padding: 10px;
+```
+
+### Zero Units
+
+Omit length units on zero values, they're unnecessary and not including them
+is slightly more performant.
+
+```scss
+// Bad
+.item-with-padding {
+  padding: 0px;
+}
+
+// Good
+.item-with-padding {
+  padding: 0;
+}
+```
+
+### Selectors with a `js-` Prefix
+
+Do not use any selector prefixed with `js-` for styling purposes. These
+selectors are intended for use only with JavaScript to allow for removal or
+renaming without breaking styling.
+
+### IDs
+
+Don't use ID selectors in CSS.
+
+```scss
+// Bad
+#my-element {
+  padding: 0;
+}
+
+// Good
+.my-element {
+  padding: 0;
+}
+```
+
+### Variables
+
+Before adding a new variable for a color or a size, guarantee:
+
+- There isn't already one
+- There isn't a similar one we can use instead.
+
+## Linting
+
+We use [SCSS Lint](https://github.com/sds/scss-lint) to check for style guide conformity. It uses the
+ruleset in `.scss-lint.yml`, which is located in the home directory of the
+project.
+
+To check if any warnings will be produced by your changes, you can run `rake
+scss_lint` in the GitLab directory. SCSS Lint will also run in GitLab CI to
+catch any warnings.
+
+If the Rake task is throwing warnings you don't understand, SCSS Lint's
+documentation includes [a full list of their linters](https://github.com/sds/scss-lint/blob/master/lib/scss_lint/linter/README.md).
+
+### Fixing issues
+
+If you want to automate changing a large portion of the codebase to conform to
+the SCSS style guide, you can use [CSSComb][csscomb]. First install
+[Node][node] and [NPM][npm], then run `npm install csscomb -g` to install
+CSSComb globally (system-wide). Run it in the GitLab directory with
+`csscomb app/assets/stylesheets` to automatically fix issues with CSS/SCSS.
+
+Note that this won't fix every problem, but it should fix a majority.
+
+### Ignoring issues
+
+If you want a line or set of lines to be ignored by the linter, you can use
+`// scss-lint:disable RuleName` ([more info](https://github.com/sds/scss-lint#disabling-linters-via-source)):
+
+```scss
+// This lint rule is disabled because it is supported only in Chrome/Safari
+// scss-lint:disable PropertySpelling
+body {
+  text-decoration-skip: ink;
+}
+// scss-lint:enable PropertySpelling
+```
+
+Make sure a comment is added on the line above the `disable` rule, otherwise the
+linter will throw a warning. `DisableLinterReason` is enabled to make sure the
+style guide isn't being ignored, and to communicate to others why the style
+guide is ignored in this instance.

+# Vue.js style guide
+
+## Linting
+
+We default to [eslint-vue-plugin](https://github.com/vuejs/eslint-plugin-vue), with the `plugin:vue/recommended`.
+Please check this [rules](https://github.com/vuejs/eslint-plugin-vue#bulb-rules) for more documentation.
+
+## Basic Rules
+
+1. The service has it's own file
+1. The store has it's own file
+1. Use a function in the bundle file to instantiate the Vue component:
+
+   ```javascript
+   // bad
+   class {
+     init() {
+       new Component({})
+     }
+   }
+
+   // good
+   document.addEventListener('DOMContentLoaded', () => new Vue({
+     el: '#element',
+     components: {
+       componentName
+     },
+     render: createElement => createElement('component-name'),
+   }));
+   ```
+
+1. Do not use a singleton for the service or the store
+
+   ```javascript
+   // bad
+   class Store {
+     constructor() {
+       if (!this.prototype.singleton) {
+         // do something
+       }
+     }
+   }
+
+   // good
+   class Store {
+     constructor() {
+       // do something
+     }
+   }
+   ```
+
+1. Use `.vue` for Vue templates. Do not use `%template` in HAML.
+
+## Naming
+
+1. **Extensions**: Use `.vue` extension for Vue components. Do not use `.js` as file extension ([#34371]).
+1. **Reference Naming**: Use PascalCase for their instances:
+
+   ```javascript
+   // bad
+   import cardBoard from 'cardBoard.vue'
+
+   components: {
+     cardBoard,
+   };
+
+   // good
+   import CardBoard from 'cardBoard.vue'
+
+   components: {
+     CardBoard,
+   };
+   ```
+
+1. **Props Naming:**  Avoid using DOM component prop names.
+1. **Props Naming:** Use kebab-case instead of camelCase to provide props in templates.
+
+   ```javascript
+   // bad
+   <component class="btn">
+
+   // good
+   <component css-class="btn">
+
+   // bad
+   <component myProp="prop" />
+
+   // good
+   <component my-prop="prop" />
+   ```
+
+[#34371]: https://gitlab.com/gitlab-org/gitlab-foss/issues/34371
+
+## Alignment
+
+1. Follow these alignment styles for the template method:
+
+   1. With more than one attribute, all attributes should be on a new line:
+
+      ```javascript
+      // bad
+      <component v-if="bar"
+          param="baz" />
+
+      <button class="btn">Click me</button>
+
+      // good
+      <component
+        v-if="bar"
+        param="baz"
+      />
+
+      <button class="btn">
+        Click me
+      </button>
+      ```
+
+   1. The tag can be inline if there is only one attribute:
+
+      ```javascript
+      // good
+        <component bar="bar" />
+
+      // good
+        <component
+          bar="bar"
+          />
+
+      // bad
+       <component
+          bar="bar" />
+      ```
+
+## Quotes
+
+1. Always use double quotes `"` inside templates and single quotes `'` for all other JS.
+
+   ```javascript
+   // bad
+   template: `
+     <button :class='style'>Button</button>
+   `
+
+   // good
+   template: `
+     <button :class="style">Button</button>
+   `
+   ```
+
+## Props
+
+1. Props should be declared as an object
+
+   ```javascript
+   // bad
+   props: ['foo']
+
+   // good
+   props: {
+     foo: {
+       type: String,
+       required: false,
+       default: 'bar'
+     }
+   }
+   ```
+
+1. Required key should always be provided when declaring a prop
+
+   ```javascript
+   // bad
+   props: {
+     foo: {
+       type: String,
+     }
+   }
+
+   // good
+   props: {
+     foo: {
+       type: String,
+       required: false,
+       default: 'bar'
+     }
+   }
+   ```
+
+1. Default key should be provided if the prop is not required.
+   _Note:_ There are some scenarios where we need to check for the existence of the property.
+   On those a default key should not be provided.
+
+   ```javascript
+   // good
+   props: {
+     foo: {
+       type: String,
+       required: false,
+     }
+   }
+
+   // good
+   props: {
+     foo: {
+       type: String,
+       required: false,
+       default: 'bar'
+     }
+   }
+
+   // good
+   props: {
+     foo: {
+       type: String,
+       required: true
+     }
+   }
+   ```
+
+## Data
+
+1. `data` method should always be a function
+
+   ```javascript
+   // bad
+   data: {
+     foo: 'foo'
+   }
+
+   // good
+   data() {
+     return {
+       foo: 'foo'
+     };
+   }
+   ```
+
+## Directives
+
+1. Shorthand `@` is preferable over `v-on`
+
+   ```javascript
+   // bad
+   <component v-on:click="eventHandler"/>
+
+   // good
+   <component @click="eventHandler"/>
+   ```
+
+1. Shorthand `:` is preferable over `v-bind`
+
+   ```javascript
+   // bad
+   <component v-bind:class="btn"/>
+
+   // good
+   <component :class="btn"/>
+   ```
+
+1. Shorthand `#` is preferable over `v-slot`
+
+   ```javascript
+   // bad
+   <template v-slot:header></template>
+
+   // good
+   <template #header></template>
+   ```
+
+## Closing tags
+
+1. Prefer self closing component tags
+
+   ```javascript
+   // bad
+   <component></component>
+
+   // good
+   <component />
+   ```
+
+## Component usage within templates
+
+1. Prefer a component's kebab-cased name over other styles when using it in a template
+
+   ```javascript
+   // bad
+   <MyComponent />
+
+   // good
+   <my-component />
+   ```
+
+## Ordering
+
+1. Tag order in `.vue` file
+
+   ```
+   <script>
+     // ...
+   </script>
+
+   <template>
+     // ...
+   </template>
+
+   // We don't use scoped styles but there are few instances of this
+   <style>
+     // ...
+   </style>
+   ```
+
+1. Properties in a Vue Component:
+   Check [order of properties in components rule](https://github.com/vuejs/eslint-plugin-vue/blob/master/docs/rules/order-in-components.md).
+
+## `:key`
+
+When using `v-for` you need to provide a *unique* `:key` attribute for each item.
+
+1. If the elements of the array being iterated have an unique `id` it is advised to use it:
+
+   ```html
+   <div
+     v-for="item in items"
+     :key="item.id"
+   >
+     <!-- content -->
+   </div>
+   ```
+
+1. When the elements being iterated don't have a unique id, you can use the array index as the `:key` attribute
+
+   ```html
+   <div
+     v-for="(item, index) in items"
+     :key="index"
+   >
+     <!-- content -->
+   </div>
+   ```
+
+1. When using `v-for` with `template` and there is more than one child element, the `:key` values must be unique. It's advised to use `kebab-case` namespaces.
+
+   ```html
+   <template v-for="(item, index) in items">
+     <span :key="`span-${index}`"></span>
+     <button :key="`button-${index}`"></button>
+   </template>
+   ```
+
+1. When dealing with nested `v-for` use the same guidelines as above.
+
+   ```html
+   <div
+     v-for="item in items"
+     :key="item.id"
+   >
+     <span
+       v-for="element in array"
+       :key="element.id"
+     >
+       <!-- content -->
+     </span>
+   </div>
+   ```
+

+1. [Vue Style Guide: Keyed v-for](https://vuejs.org/v2/style-guide/#Keyed-v-for-essential )
+
+## Vue and Bootstrap
+
+1. Tooltips: Do not rely on `has-tooltip` class name for Vue components
+
+   ```javascript
+   // bad
+   <span
+     class="has-tooltip"
+     title="Some tooltip text">
+     Text
+   </span>
+
+   // good
+   <span
+     v-tooltip
+     title="Some tooltip text">
+     Text
+   </span>
+   ```
+
+1. Tooltips: When using a tooltip, include the tooltip directive, `./app/assets/javascripts/vue_shared/directives/tooltip.js`
+
+1. Don't change `data-original-title`.
+
+   ```javascript
+   // bad
+   <span data-original-title="tooltip text">Foo</span>
+
+   // good
+   <span title="tooltip text">Foo</span>
+
+   $('span').tooltip('_fixTitle');
+   ```
+
+## The JavaScript/Vue Accord
+
+The goal of this accord is to make sure we are all on the same page.
+
+1. When writing Vue, you may not use jQuery in your application.
+   1. If you need to grab data from the DOM, you may query the DOM 1 time while bootstrapping your application to grab data attributes using `dataset`. You can do this without jQuery.
+   1. You may use a jQuery dependency in Vue.js following [this example from the docs](https://vuejs.org/v2/examples/select2.html).
+   1. If an outside jQuery Event needs to be listen to inside the Vue application, you may use jQuery event listeners.
+   1. We will avoid adding new jQuery events when they are not required. Instead of adding new jQuery events take a look at [different methods to do the same task](https://vuejs.org/v2/api/#vm-emit).
+1. You may query the `window` object 1 time, while bootstrapping your application for application specific data (e.g. `scrollTo` is ok to access anytime). Do this access during the bootstrapping of your application.
+1. You may have a temporary but immediate need to create technical debt by writing code that does not follow our standards, to be refactored later. Maintainers need to be ok with the tech debt in the first place. An issue should be created for that tech debt to evaluate it further and discuss. In the coming months you should fix that tech debt, with it's priority to be determined by maintainers.
+1. When creating tech debt you must write the tests for that code before hand and those tests may not be rewritten. e.g. jQuery tests rewritten to Vue tests.
+1. You may choose to use VueX as a centralized state management. If you choose not to use VueX, you must use the *store pattern* which can be found in the [Vue.js documentation](https://vuejs.org/v2/guide/state-management.html#Simple-State-Management-from-Scratch).
+1. Once you have chosen a centralized state management solution you must use it for your entire application. i.e. Don't mix and match your state management solutions.

-# Style guides and linting
+---
+redirect_to: 'style/javascript.md'
+---
 
-See the relevant style guides for our guidelines and for information on linting:
-
-## JavaScript
-
-We defer to [Airbnb][airbnb-js-style-guide] on most style-related
-conventions and enforce them with eslint.
-
-See [our current .eslintrc](https://gitlab.com/gitlab-org/gitlab/blob/master/.eslintrc.yml) for specific rules and patterns.
-
-### Common
-
-#### ESlint
-
-1. **Never** disable eslint rules unless you have a good reason.
-   You may see a lot of legacy files with `/* eslint-disable some-rule, some-other-rule */`
-   at the top, but legacy files are a special case.  Any time you develop a new feature or
-   refactor an existing one, you should abide by the eslint rules.
-
-1. **Never Ever EVER** disable eslint globally for a file
-
-   ```javascript
-   // bad
-   /* eslint-disable */
-
-   // better
-   /* eslint-disable some-rule, some-other-rule */
-
-   // best
-   // nothing :)
-   ```
-
-1. If you do need to disable a rule for a single violation, try to do it as locally as possible
-
-   ```javascript
-   // bad
-   /* eslint-disable no-new */
-
-   import Foo from 'foo';
-
-   new Foo();
-
-   // better
-   import Foo from 'foo';
-
-   // eslint-disable-next-line no-new
-   new Foo();
-   ```
-
-1. There are few rules that we need to disable due to technical debt. Which are:
-   1. [no-new](https://eslint.org/docs/rules/no-new)
-   1. [class-methods-use-this](https://eslint.org/docs/rules/class-methods-use-this)
-
-1. When they are needed _always_ place ESlint directive comment blocks on the first line of a script,
-   followed by any global declarations, then a blank newline prior to any imports or code.
-
-   ```javascript
-   // bad
-   /* global Foo */
-   /* eslint-disable no-new */
-   import Bar from './bar';
-
-   // good
-   /* eslint-disable no-new */
-   /* global Foo */
-
-   import Bar from './bar';
-   ```
-
-1. **Never** disable the `no-undef` rule. Declare globals with `/* global Foo */` instead.
-
-1. When declaring multiple globals, always use one `/* global [name] */` line per variable.
-
-   ```javascript
-   // bad
-   /* globals Flash, Cookies, jQuery */
-
-   // good
-   /* global Flash */
-   /* global Cookies */
-   /* global jQuery */
-   ```
-
-1. Use up to 3 parameters for a function or class. If you need more accept an Object instead.
-
-   ```javascript
-   // bad
-   fn(p1, p2, p3, p4) {}
-
-   // good
-   fn(options) {}
-   ```
-
-#### Modules, Imports, and Exports
-
-1. Use ES module syntax to import modules
-
-   ```javascript
-   // bad
-   const SomeClass = require('some_class');
-
-   // good
-   import SomeClass from 'some_class';
-
-   // bad
-   module.exports = SomeClass;
-
-   // good
-   export default SomeClass;
-   ```
-
-   Import statements are following usual naming guidelines, for example object literals use camel case:
-
-   ```javascript
-   // some_object file
-   export default {
-     key: 'value',
-   };
-
-   // bad
-   import ObjectLiteral from 'some_object';
-
-   // good
-   import objectLiteral from 'some_object';
-   ```
-
-1. Relative paths: when importing a module in the same directory, a child
-   directory, or an immediate parent directory prefer relative paths.  When
-   importing a module which is two or more levels up, prefer either `~/` or `ee/`.
-
-   In **app/assets/javascripts/my-feature/subdir**:
-
-   ```javascript
-   // bad
-   import Foo from '~/my-feature/foo';
-   import Bar from '~/my-feature/subdir/bar';
-   import Bin from '~/my-feature/subdir/lib/bin';
-
-   // good
-   import Foo from '../foo';
-   import Bar from './bar';
-   import Bin from './lib/bin';
-   ```
-
-   In **spec/javascripts**:
-
-   ```javascript
-   // bad
-   import Foo from '../../app/assets/javascripts/my-feature/foo';
-
-   // good
-   import Foo from '~/my-feature/foo';
-   ```
-
-   When referencing an **EE component**:
-
-   ```javascript
-   // bad
-   import Foo from '../../../../../ee/app/assets/javascripts/my-feature/ee-foo';
-
-   // good
-   import Foo from 'ee/my-feature/foo';
-   ```
-
-1. Avoid using IIFE. Although we have a lot of examples of files which wrap their
-   contents in IIFEs (immediately-invoked function expressions),
-   this is no longer necessary after the transition from Sprockets to webpack.
-   Do not use them anymore and feel free to remove them when refactoring legacy code.
-
-1. Avoid adding to the global namespace.
-
-   ```javascript
-   // bad
-   window.MyClass = class { /* ... */ };
-
-   // good
-   export default class MyClass { /* ... */ }
-   ```
-
-1. Side effects are forbidden in any script which contains export
-
-   ```javascript
-   // bad
-   export default class MyClass { /* ... */ }
-
-   document.addEventListener("DOMContentLoaded", function(event) {
-     new MyClass();
-   }
-   ```
-
-#### Data Mutation and Pure functions
-
-1. Strive to write many small pure functions, and minimize where mutations occur.
-
-   ```javascript
-   // bad
-   const values = {foo: 1};
-
-   function impureFunction(items) {
-     const bar = 1;
-
-     items.foo = items.a * bar + 2;
-
-     return items.a;
-   }
-
-   const c = impureFunction(values);
-
-   // good
-   var values = {foo: 1};
-
-   function pureFunction (foo) {
-     var bar = 1;
-
-     foo = foo * bar + 2;
-
-     return foo;
-   }
-
-   var c = pureFunction(values.foo);
-    ```
-
-1. Avoid constructors with side-effects.
-   Although we aim for code without side-effects we need some side-effects for our code to run.
-
-   If the class won't do anything if we only instantiate it, it's ok to add side effects into the constructor (_Note:_ The following is just an example. If the only purpose of the class is to add an event listener and handle the callback a function will be more suitable.)
-
-   ```javascript
-   // Bad
-   export class Foo {
-     constructor() {
-       this.init();
-     }
-     init() {
-       document.addEventListener('click', this.handleCallback)
-     },
-     handleCallback() {
-
-     }
-   }
-
-   // Good
-   export class Foo {
-     constructor() {
-       document.addEventListener()
-     }
-     handleCallback() {
-     }
-   }
-   ```
-
-   On the other hand, if a class only needs to extend a third party/add event listeners in some specific cases, they should be initialized outside of the constructor.
-
-1. Prefer `.map`, `.reduce` or `.filter` over `.forEach`
-   A forEach will most likely cause side effects, it will be mutating the array being iterated. Prefer using `.map`,
-   `.reduce` or `.filter`
-
-   ```javascript
-   const users = [ { name: 'Foo' }, { name: 'Bar' } ];
-
-   // bad
-   users.forEach((user, index) => {
-     user.id = index;
-   });
-
-   // good
-   const usersWithId = users.map((user, index) => {
-     return Object.assign({}, user, { id: index });
-   });
-   ```
-
-#### Parse Strings into Numbers
-
-1. `parseInt()` is preferable over `Number()` or `+`
-
-   ```javascript
-   // bad
-   +'10' // 10
-
-   // good
-   Number('10') // 10
-
-   // better
-   parseInt('10', 10);
-   ```
-
-#### CSS classes used for JavaScript
-
-1. If the class is being used in JavaScript it needs to be prepend with `js-`
-
-   ```html
-   // bad
-   <button class="add-user">
-     Add User
-   </button>
-
-   // good
-   <button class="js-add-user">
-     Add User
-   </button>
-   ```
-
-### Vue.js
-
-#### `eslint-vue-plugin`
-
-We default to [eslint-vue-plugin][eslint-plugin-vue], with the `plugin:vue/recommended`.
-Please check this [rules][eslint-plugin-vue-rules] for more documentation.
-
-#### Basic Rules
-
-1. The service has it's own file
-1. The store has it's own file
-1. Use a function in the bundle file to instantiate the Vue component:
-
-   ```javascript
-   // bad
-   class {
-     init() {
-       new Component({})
-     }
-   }
-
-   // good
-   document.addEventListener('DOMContentLoaded', () => new Vue({
-     el: '#element',
-     components: {
-       componentName
-     },
-     render: createElement => createElement('component-name'),
-   }));
-   ```
-
-1. Do not use a singleton for the service or the store
-
-   ```javascript
-   // bad
-   class Store {
-     constructor() {
-       if (!this.prototype.singleton) {
-         // do something
-       }
-     }
-   }
-
-   // good
-   class Store {
-     constructor() {
-       // do something
-     }
-   }
-   ```
-
-1. Use `.vue` for Vue templates. Do not use `%template` in HAML.
-
-#### Naming
-
-1. **Extensions**: Use `.vue` extension for Vue components. Do not use `.js` as file extension ([#34371]).
-1. **Reference Naming**: Use PascalCase for their instances:
-
-   ```javascript
-   // bad
-   import cardBoard from 'cardBoard.vue'
-
-   components: {
-     cardBoard,
-   };
-
-   // good
-   import CardBoard from 'cardBoard.vue'
-
-   components: {
-     CardBoard,
-   };
-   ```
-
-1. **Props Naming:**  Avoid using DOM component prop names.
-1. **Props Naming:** Use kebab-case instead of camelCase to provide props in templates.
-
-   ```javascript
-   // bad
-   <component class="btn">
-
-   // good
-   <component css-class="btn">
-
-   // bad
-   <component myProp="prop" />
-
-   // good
-   <component my-prop="prop" />
-   ```
-
-[#34371]: https://gitlab.com/gitlab-org/gitlab-foss/issues/34371
-
-#### Alignment
-
-1. Follow these alignment styles for the template method:
-
-   1. With more than one attribute, all attributes should be on a new line:
-
-      ```javascript
-      // bad
-      <component v-if="bar"
-          param="baz" />
-
-      <button class="btn">Click me</button>
-
-      // good
-      <component
-        v-if="bar"
-        param="baz"
-      />
-
-      <button class="btn">
-        Click me
-      </button>
-      ```
-
-   1. The tag can be inline if there is only one attribute:
-
-      ```javascript
-      // good
-        <component bar="bar" />
-
-      // good
-        <component
-          bar="bar"
-          />
-
-      // bad
-       <component
-          bar="bar" />
-      ```
-
-#### Quotes
-
-1. Always use double quotes `"` inside templates and single quotes `'` for all other JS.
-
-   ```javascript
-   // bad
-   template: `
-     <button :class='style'>Button</button>
-   `
-
-   // good
-   template: `
-     <button :class="style">Button</button>
-   `
-   ```
-
-#### Props
-
-1. Props should be declared as an object
-
-   ```javascript
-   // bad
-   props: ['foo']
-
-   // good
-   props: {
-     foo: {
-       type: String,
-       required: false,
-       default: 'bar'
-     }
-   }
-   ```
-
-1. Required key should always be provided when declaring a prop
-
-   ```javascript
-   // bad
-   props: {
-     foo: {
-       type: String,
-     }
-   }
-
-   // good
-   props: {
-     foo: {
-       type: String,
-       required: false,
-       default: 'bar'
-     }
-   }
-   ```
-
-1. Default key should be provided if the prop is not required.
-   _Note:_ There are some scenarios where we need to check for the existence of the property.
-   On those a default key should not be provided.
-
-   ```javascript
-   // good
-   props: {
-     foo: {
-       type: String,
-       required: false,
-     }
-   }
-
-   // good
-   props: {
-     foo: {
-       type: String,
-       required: false,
-       default: 'bar'
-     }
-   }
-
-   // good
-   props: {
-     foo: {
-       type: String,
-       required: true
-     }
-   }
-   ```
-
-#### Data
-
-1. `data` method should always be a function
-
-   ```javascript
-   // bad
-   data: {
-     foo: 'foo'
-   }
-
-   // good
-   data() {
-     return {
-       foo: 'foo'
-     };
-   }
-   ```
-
-#### Directives
-
-1. Shorthand `@` is preferable over `v-on`
-
-   ```javascript
-   // bad
-   <component v-on:click="eventHandler"/>
-
-   // good
-   <component @click="eventHandler"/>
-   ```
-
-1. Shorthand `:` is preferable over `v-bind`
-
-   ```javascript
-   // bad
-   <component v-bind:class="btn"/>
-
-   // good
-   <component :class="btn"/>
-   ```
-
-1. Shorthand `#` is preferable over `v-slot`
-
-   ```javascript
-   // bad
-   <template v-slot:header></template>
-
-   // good
-   <template #header></template>
-   ```
-
-#### Closing tags
-
-1. Prefer self closing component tags
-
-   ```javascript
-   // bad
-   <component></component>
-
-   // good
-   <component />
-   ```
-
-#### Component usage within templates
-
-1. Prefer a component's kebab-cased name over other styles when using it in a template
-
-   ```javascript
-   // bad
-   <MyComponent />
-
-   // good
-   <my-component />
-   ```
-
-#### Ordering
-
-1. Tag order in `.vue` file
-
-   ```
-   <script>
-     // ...
-   </script>
-
-   <template>
-     // ...
-   </template>
-
-   // We don't use scoped styles but there are few instances of this
-   <style>
-     // ...
-   </style>
-   ```
-
-1. Properties in a Vue Component:
-   Check [order of properties in components rule][vue-order].
-
-#### `:key`
-
-When using `v-for` you need to provide a *unique* `:key` attribute for each item.
-
-1. If the elements of the array being iterated have an unique `id` it is advised to use it:
-
-   ```html
-   <div
-     v-for="item in items"
-     :key="item.id"
-   >
-     <!-- content -->
-   </div>
-   ```
-
-1. When the elements being iterated don't have a unique id, you can use the array index as the `:key` attribute
-
-   ```html
-   <div
-     v-for="(item, index) in items"
-     :key="index"
-   >
-     <!-- content -->
-   </div>
-   ```
-
-1. When using `v-for` with `template` and there is more than one child element, the `:key` values must be unique. It's advised to use `kebab-case` namespaces.
-
-   ```html
-   <template v-for="(item, index) in items">
-     <span :key="`span-${index}`"></span>
-     <button :key="`button-${index}`"></button>
-   </template>
-   ```
-
-1. When dealing with nested `v-for` use the same guidelines as above.

-   </span>
-   ```
-
-1. Tooltips: When using a tooltip, include the tooltip directive, `./app/assets/javascripts/vue_shared/directives/tooltip.js`
-
-1. Don't change `data-original-title`.
-
-   ```javascript
-   // bad
-   <span data-original-title="tooltip text">Foo</span>
-
-   // good
-   <span title="tooltip text">Foo</span>
-
-   $('span').tooltip('_fixTitle');
-   ```
-
-### The JavaScript/Vue Accord
-
-The goal of this accord is to make sure we are all on the same page.
-
-1. When writing Vue, you may not use jQuery in your application.
-   1. If you need to grab data from the DOM, you may query the DOM 1 time while bootstrapping your application to grab data attributes using `dataset`. You can do this without jQuery.
-   1. You may use a jQuery dependency in Vue.js following [this example from the docs](https://vuejs.org/v2/examples/select2.html).
-   1. If an outside jQuery Event needs to be listen to inside the Vue application, you may use jQuery event listeners.
-   1. We will avoid adding new jQuery events when they are not required. Instead of adding new jQuery events take a look at [different methods to do the same task](https://vuejs.org/v2/api/#vm-emit).
-1. You may query the `window` object 1 time, while bootstrapping your application for application specific data (e.g. `scrollTo` is ok to access anytime). Do this access during the bootstrapping of your application.
-1. You may have a temporary but immediate need to create technical debt by writing code that does not follow our standards, to be refactored later. Maintainers need to be ok with the tech debt in the first place. An issue should be created for that tech debt to evaluate it further and discuss. In the coming months you should fix that tech debt, with it's priority to be determined by maintainers.
-1. When creating tech debt you must write the tests for that code before hand and those tests may not be rewritten. e.g. jQuery tests rewritten to Vue tests.
-1. You may choose to use VueX as a centralized state management. If you choose not to use VueX, you must use the *store pattern* which can be found in the [Vue.js documentation](https://vuejs.org/v2/guide/state-management.html#Simple-State-Management-from-Scratch).
-1. Once you have chosen a centralized state management solution you must use it for your entire application. i.e. Don't mix and match your state management solutions.

-This style guide recommends best practices for SCSS to make styles easy to read,
-easy to maintain, and performant for the end-user.

-## Rules
-
-### Utility Classes
-
-As part of the effort for [cleaning up our CSS and moving our components into GitLab-UI](https://gitlab.com/groups/gitlab-org/-/epics/950)
-led by the [GitLab UI WG](https://gitlab.com/gitlab-com/www-gitlab-com/merge_requests/20623) we prefer the use of utility classes over adding new CSS. However, complex CSS can be addressed by adding component classes.
-
-#### Where are utility classes defined?
-
-- [Bootstrap's Utility Classes](https://getbootstrap.com/docs/4.3/utilities/)
-- [`common.scss`](https://gitlab.com/gitlab-org/gitlab/blob/master/app/assets/stylesheets/framework/common.scss) (old)
-- [`utilities.scss`](https://gitlab.com/gitlab-org/gitlab/blob/master/app/assets/stylesheets/utilities.scss) (new)
-
-#### Where should I put new utility classes?
-
-New utility classes should be added to [`utilities.scss`](https://gitlab.com/gitlab-org/gitlab/blob/master/app/assets/stylesheets/utilities.scss). Existing classes include:
-
-| Name | Pattern | Example |
-|------|---------|---------|
-| Background color | `.bg-{variant}-{shade}` | `.bg-warning-400` |
-| Text color | `.text-{variant}-{shade}` | `.text-success-500` |
-| Font size | `.text-{size}` | `.text-2` |
-
-- `{variant}` is one of 'primary', 'secondary', 'success', 'warning', 'error'
-- `{shade}` is one of the shades listed on [colors](https://design.gitlab.com/product-foundations/colors/)
-- `{size}` is a number from 1-6 from our [Type scale](https://design.gitlab.com/product-foundations/typography)
-
-#### When should I create component classes?
-
-We recommend a "utility-first" approach.
-
-1. Start with utility classes.
-1. If composing utility classes into a component class removes code duplication and encapsulates a clear responsibility, do it.
-
-This encourages an organic growth of component classes and prevents the creation of one-off unreusable classes. Also, the kind of classes that emerge from "utility-first" tend to be design-centered (e.g. `.button`, `.alert`, `.card`) rather than domain-centered (e.g. `.security-report-widget`, `.commit-header-icon`).
-
-Examples of component classes that were created using "utility-first" include:
-
-- [`.circle-icon-container`](https://gitlab.com/gitlab-org/gitlab/blob/579fa8b8ec7eb38d40c96521f517c9dab8c3b97a/app/assets/stylesheets/framework/icons.scss#L85)
-- [`.d-flex-center`](https://gitlab.com/gitlab-org/gitlab/blob/900083d89cd6af391d26ab7922b3f64fa2839bef/app/assets/stylesheets/framework/common.scss#L425)
-
-Inspiration:
-
-- <https://tailwindcss.com/docs/utility-first/>
-- <https://tailwindcss.com/docs/extracting-components/>
-
-### Naming
-
-Filenames should use `snake_case`.
-
-CSS classes should use the `lowercase-hyphenated` format rather than
-`snake_case` or `camelCase`.
-
-```scss
-// Bad
-.class_name {
-  color: #fff;
-}
-
-// Bad
-.className {
-  color: #fff;
-}
-
-// Good
-.class-name {
-  color: #fff;
-}
-```
-
-### Formatting
-
-You should always use a space before a brace, braces should be on the same
-line, each property should each get its own line, and there should be a space
-between the property and its value.
-
-```scss
-// Bad
-.container-item {
-  width: 100px; height: 100px;
-  margin-top: 0;
-}
-
-// Bad
-.container-item
-{
-  width: 100px;
-  height: 100px;
-  margin-top: 0;
-}
-
-// Bad
-.container-item{
-  width:100px;
-  height:100px;
-  margin-top:0;
-}
-
-// Good
-.container-item {
-  width: 100px;
-  height: 100px;
-  margin-top: 0;
-}
-```
-
-Note that there is an exception for single-line rulesets, although these are
-not typically recommended.
-
-```scss
-p { margin: 0; padding: 0; }
-```
-
-### Colors
-
-HEX (hexadecimal) colors should use shorthand where possible, and should use
-lower case letters to differentiate between letters and numbers, e.g. `#E3E3E3`
-vs. `#e3e3e3`.
-
-```scss
-// Bad
-p {
-  color: #ffffff;
-}
-
-// Bad
-p {
-  color: #FFFFFF;
-}
-
-// Good
-p {
-  color: #fff;
-}
-```
-
-### Indentation
-
-Indentation should always use two spaces for each indentation level.
-
-```scss
-// Bad, four spaces
-p {
-    color: #f00;
-}
-
-// Good
-p {
-  color: #f00;
-}
-```
-
-### Semicolons
-
-Always include semicolons after every property. When the stylesheets are
-minified, the semicolons will be removed automatically.
-
-```scss
-// Bad
-.container-item {
-  width: 100px;
-  height: 100px
-}
-
-// Good
-.container-item {
-  width: 100px;
-  height: 100px;
-}
-```
-
-### Shorthand
-
-The shorthand form should be used for properties that support it.
-
-```scss
-// Bad
-margin: 10px 15px 10px 15px;
-padding: 10px 10px 10px 10px;
-
-// Good
-margin: 10px 15px;
-padding: 10px;
-```
-
-### Zero Units
-
-Omit length units on zero values, they're unnecessary and not including them
-is slightly more performant.
-
-```scss
-// Bad
-.item-with-padding {
-  padding: 0px;
-}
-
-// Good
-.item-with-padding {
-  padding: 0;
-}
-```
-
-### Selectors with a `js-` Prefix
-
-Do not use any selector prefixed with `js-` for styling purposes. These
-selectors are intended for use only with JavaScript to allow for removal or
-renaming without breaking styling.
-
-### IDs
-
-Don't use ID selectors in CSS.
-
-```scss
-// Bad
-#my-element {
-  padding: 0;
-}
-
-// Good
-.my-element {
-  padding: 0;
-}
-```
-
-### Variables
-
-Before adding a new variable for a color or a size, guarantee:
-
-- There isn't already one
-- There isn't a similar one we can use instead.
-
-## Linting
-
-We use [SCSS Lint](https://github.com/sds/scss-lint) to check for style guide conformity. It uses the
-ruleset in `.scss-lint.yml`, which is located in the home directory of the
-project.
-
-To check if any warnings will be produced by your changes, you can run `rake
-scss_lint` in the GitLab directory. SCSS Lint will also run in GitLab CI to
-catch any warnings.
-
-If the Rake task is throwing warnings you don't understand, SCSS Lint's
-documentation includes [a full list of their linters][scss-lint-documentation](https://github.com/sds/scss-lint/blob/master/lib/scss_lint/linter/README.md).
-
-### Fixing issues
-
-If you want to automate changing a large portion of the codebase to conform to
-the SCSS style guide, you can use [CSSComb][csscomb]. First install
-[Node][node] and [NPM][npm], then run `npm install csscomb -g` to install
-CSSComb globally (system-wide). Run it in the GitLab directory with
-`csscomb app/assets/stylesheets` to automatically fix issues with CSS/SCSS.
-
-Note that this won't fix every problem, but it should fix a majority.
-
-### Ignoring issues
-
-If you want a line or set of lines to be ignored by the linter, you can use
-`// scss-lint:disable RuleName` ([more info](https://github.com/sds/scss-lint#disabling-linters-via-source)):
-
-```scss
-// This lint rule is disabled because it is supported only in Chrome/Safari
-// scss-lint:disable PropertySpelling
-body {
-  text-decoration-skip: ink;
-}
-// scss-lint:enable PropertySpelling
-```
-
-Make sure a comment is added on the line above the `disable` rule, otherwise the
-linter will throw a warning. `DisableLinterReason` is enabled to make sure the
-style guide isn't being ignored, and to communicate to others why the style
-guide is ignored in this instance.

+# Tooling
+
+## ESLint
+
+We use ESLint to encapsulate and enforce frontend code standards. Our configuration may be found in the [`gitlab-eslint-config`](https://gitlab.com/gitlab-org/gitlab-eslint-config) project.
+
+### Disabling ESLint in new files
+
+Do not disable ESLint when creating new files. Existing files may have existing rules
+disabled due to legacy compatibility reasons but they are in the process of being refactored.
+
+Do not disable specific ESLint rules. To avoid introducing technical debt, you may disable the following
+rules only if you are invoking/instantiating existing code modules.
+
+- [`no-new`](https://eslint.org/docs/rules/no-new)
+- [`class-method-use-this`](https://eslint.org/docs/rules/class-methods-use-this)
+
+NOTE: **Note:**
+Disable these rules on a per-line basis. This makes it easier to refactor
+in the future. E.g. use `eslint-disable-next-line` or `eslint-disable-line`.
+
+### Disabling ESLint for a single violation
+
+If you do need to disable a rule for a single violation, disable it for the smallest amount of code necessary:
+
+```javascript
+// bad
+/* eslint-disable no-new */
+
+import Foo from 'foo';
+
+new Foo();
+
+// better
+import Foo from 'foo';
+
+// eslint-disable-next-line no-new
+new Foo();
+```
+
+### The `no-undef` rule and declaring globals
+
+**Never** disable the `no-undef` rule. Declare globals with `/* global Foo */` instead.
+
+When declaring multiple globals, always use one `/* global [name] */` line per variable.
+
+```javascript
+// bad
+/* globals Flash, Cookies, jQuery */
+
+// good
+/* global Flash */
+/* global Cookies */
+/* global jQuery */
+```
+
+## Formatting with Prettier
+
+Our code is automatically formatted with [Prettier](https://prettier.io) to follow our style guides. Prettier is taking care of formatting .js, .vue, and .scss files based on the standard prettier rules. You can find all settings for Prettier in `.prettierrc`.
+
+### Editor
+
+The easiest way to include prettier in your workflow is by setting up your preferred editor (all major editors are supported) accordingly. We suggest setting up prettier to run automatically when each file is saved. Find [here](https://prettier.io/docs/en/editors.html) the best way to set it up in your preferred editor.
+
+Please take care that you only let Prettier format the same file types as the global Yarn script does (.js, .vue, and .scss). In VSCode by example you can easily exclude file formats in your settings file:
+
+```
+  "prettier.disableLanguages": [
+      "json",
+      "markdown"
+  ],
+```
+
+### Yarn Script
+
+The following yarn scripts are available to do global formatting:
+
+```
+yarn prettier-staged-save
+```
+
+Updates all currently staged files (based on `git diff`) with Prettier and saves the needed changes.
+
+```
+yarn prettier-staged
+```
+
+Checks all currently staged files (based on `git diff`) with Prettier and log which files would need manual updating to the console.
+
+```
+yarn prettier-all
+```
+
+Checks all files with Prettier and logs which files need manual updating to the console.
+
+```
+yarn prettier-all-save
+```
+
+Formats all files in the repository with Prettier. (This should only be used to test global rule updates otherwise you would end up with huge MR's).
+
+The source of these Yarn scripts can be found in `/scripts/frontend/prettier.js`.
+
+#### Scripts during Conversion period
+
+```
+node ./scripts/frontend/prettier.js check-all ./vendor/
+```
+
+This will go over all files in a specific folder check it.
+
+```
+node ./scripts/frontend/prettier.js save-all ./vendor/
+```
+
+This will go over all files in a specific folder and save it.
+
+### VSCode Settings
+
+#### Select Prettier as default formatter
+
+To select Prettier as a formatter, add the following properties to your User or Workspace Settings:
+
+```javascript
+{
+  "[html]": {
+    "editor.defaultFormatter": "esbenp.prettier-vscode"
+  },
+  "[javascript]": {
+    "editor.defaultFormatter": "esbenp.prettier-vscode"
+  },
+  "[vue]": {
+    "editor.defaultFormatter": "esbenp.prettier-vscode"
+  }
+}
+```
+
+#### Format on Save
+
+To automatically format your files with Prettier, add the following properties to your User or Workspace Settings:
+
+```javascript
+{
+  "[html]": {
+    "editor.formatOnSave": true
+  },
+  "[javascript]": {
+    "editor.formatOnSave": true
+  },
+  "[vue]": {

+### Testing with GDK
+
+To be sure that the flag is set correctly and it goes into Gitaly, you can check
+the integration by using GDK:
+
+1. The state of the flag must be observable. To check it, you need to enable it
+   by fetching the Prometheus metrics:
+   1. Navigate to GDK's root directory.
+   1. Make sure you have the proper branch checked out for Gitaly.
+   1. Recompile it with `make gitaly-setup` and restart the service with `gdk restart gitaly`.
+   1. Make sure your setup is runnig: `gdk status | grep praefect`.
+   1. Check what config file is used: `cat ./services/praefect/run | grep praefect` value of the `-config` flag
+   1. Uncomment `prometheus_listen_addr` in the configuration file and run `gdk restart gitaly`.
+
+1. Make sure that the flag is not enabled yet:
+   1. Perform whatever action is required to trigger your changes (project creation,
+      submitting commit, observing history, etc.).
+   1. Check that the list of current metrics has the new counter for the feature flag:
+
+      ```sh
+      curl --silent http://localhost:9236/metrics | grep go_find_all_tags
+      ```
+
+1. Once you observe the metrics for the new feature flag and it increments, you
+   can enable the new feature:
+   1. Navigate to GDK's root directory.
+   1. Start a Rails console:
+
+      ```sh
+      bundle install && bundle exec rails console
+      ```
+
+   1. Check the list of feature flags:
+
+      ```ruby
+      Feature::Gitaly.server_feature_flags
+      ```
+
+      It should be disabled `"gitaly-feature-go-find-all-tags"=>"false"`.
+   1. Enable it:
+
+      ```ruby
+      Feature.enable('gitaly_go_find_all_tags')
+      ```
+
+   1. Exit the Rails console and perform whatever action is required to trigger
+      your changes (project creation, submitting commit, observing history, etc.).
+   1. Verify the feature is on by observing the metrics for it:
+
+      ```sh
+      curl --silent http://localhost:9236/metrics | grep go_find_all_tags
+      ```

+## Distributing Go binaries
+
+With the exception of [GitLab Runner](https://gitlab.com/gitlab-org/gitlab-runner),
+which publishes its own binaries, our Go binaries are created by projects
+managed by the [Distribution group](https://about.gitlab.com/handbook/product/categories/#distribution-group).
+
+The [Omnibus GitLab](https://gitlab.com/gitlab-org/omnibus-gitlab) project creates a
+single, monolithic operating system package containing all the binaries, while
+the [Cloud-Native GitLab (CNG)](https://gitlab.com/gitlab-org/build/CNG) project
+publishes a set of Docker images and Helm charts to glue them together.
+
+Both approaches use the same version of Go for all projects, so it's important
+to ensure all our Go-using projects have at least one Go version in common in
+their test matrices. You can check the version of Go currently being used by
+[Omnibus](https://gitlab.com/gitlab-org/gitlab-omnibus-builder/blob/master/docker/Dockerfile_debian_10#L59),
+and the version being used for [CNG](https://gitlab.com/gitlab-org/build/cng/blob/master/ci_files/variables.yml#L12).
+
+### Updating Go version
+
+We should always use a [supported version](https://golang.org/doc/devel/release.html#policy)
+of Go, i.e., one of the three most recent minor releases, and should always use
+the most recent patch-level for that version, as it may contain security fixes.
+
+Changing the version affects every project being compiled, so it's important to
+ensure that all projects have been updated to test against the new Go version
+before changing the package builders to use it. Despite [Go's compatibility promise](https://golang.org/doc/go1compat),
+changes between minor versions can expose bugs or cause problems in our projects.
+
+Once you've picked a new Go version to use, the steps to update Omnibus and CNG
+are:
+
+- [Create a merge request in the CNG project](https://gitlab.com/gitlab-org/build/CNG/edit/master/ci_files/variables.yml?branch_name=update-go-version),
+   updating the `GO_VERSION` in `ci_files/variables.yml`.
+- Create a merge request in the [`gitlab-omnibus-builder` project](https://gitlab.com/gitlab-org/gitlab-omnibus-builder),
+   updating every file in the `docker/` directory so the `GO_VERSION` is set
+   appropriately. [Here's an example](https://gitlab.com/gitlab-org/gitlab-omnibus-builder/merge_requests/125/diffs).
+- Tag a new release of `gitlab-omnibus-builder` containing the change.
+- [Create a merge request in the `gitlab-omnibus` project](https://gitlab.com/gitlab-org/omnibus-gitlab/edit/master/.gitlab-ci.yml?branch_name=update-gitlab-omnibus-builder-version),
+   updating the `BUILDER_IMAGE_REVISION` to match the newly-created tag.
+
+To reduce unnecessary differences between two distribution methods, Omnibus and
+CNG **should always use the same Go version**.

+##### Vue components interpolation
+
+When translating UI text in Vue components, you might want to include child components inside
+the translation string.
+You could not use a JavaScript-only solution to render the translation,
+because Vue would not be aware of the child components and would render them as plain text.
+
+For this use case, you should use the `gl-sprintf` component which is maintained
+in **GitLab UI**.
+
+The `gl-sprintf` component accepts a `message` property, which is the translatable string,
+and it exposes a named slot for every placeholder in the string, which lets you include Vue
+components easily.
+
+Assume you want to print the translatable string
+`Pipeline %{pipelineId} triggered %{timeago} by %{author}`. To replace the `%{timeago}` and
+`%{author}` placeholders with Vue components, here's how you would do that with `gl-sprintf`:
+
+```html
+<template>
+  <div>
+    <gl-sprintf :message="__('Pipeline %{pipelineId} triggered %{timeago} by %{author}')">
+      <template #pipelineId>{{ pipeline.id }}</template>
+      <template #timeago>
+        <timeago :time="pipeline.triggerTime" />
+      </template>
+      <template #author>
+        <gl-avatar-labeled
+          :src="pipeline.triggeredBy.avatarPath"
+          :label="pipeline.triggeredBy.name"
+        />
+      </template>
+    </gl-sprintf>
+  </div>
+</template>
+```
+
+For more information, see the [`gl-sprintf`](https://gitlab-org.gitlab.io/gitlab-ui/?path=/story/base-sprintf--default) documentation.

+## Exception Handling
+
+It often happens that you catch the exception and want to track it.
+
+It should be noted that manual logging of exceptions is not allowed, as:
+
+1. Manual logged exceptions can leak confidential data,
+1. Manual logged exception very often require to clean backtrace
+   which reduces the boilerplate,
+1. Very often manually logged exception needs to be tracked to Sentry as well,
+1. Manually logged exceptions does not use `correlation_id`, which makes hard
+   to pin them to request, user and context in which this exception was raised,
+1. It is very likely that manually logged exceptions will end-up across
+   multiple files, which increases burden scraping all logging files.
+
+To avoid duplicating and having consistent behavior the `Gitlab::ErrorTracking`
+provides helper methods to track exceptions:
+
+1. `Gitlab::ErrorTracking.track_and_raise_exception`: this method logs,
+   sends exception to Sentry (if configured) and re-raises the exception,
+1. `Gitlab::ErrorTracking.track_exception`: this method only logs
+   and sends exception to Sentry (if configured),
+1. `Gitlab::ErrorTracking.log_exception`: this method only logs the exception,
+   and DOES NOT send the exception to Sentry,
+1. `Gitlab::ErrorTracking.track_and_raise_for_dev_exception`: this method logs,
+   sends exception to Sentry (if configured) and re-raises the exception
+  for development and test enviroments.
+
+It is advised to only use `Gitlab::ErrorTracking.track_and_raise_exception`
+and `Gitlab::ErrorTracking.track_exception` as presented on below examples.
+
+Consider adding additional extra parameters to provide more context
+for each tracked exception.
+
+### Example

+class MyService < ::BaseService
+  def execute
+    project.perform_expensive_operation
+
+    success

 There are some cases where this may be needed. If this is the case this should
 be clearly mentioned in the merge request description.
 
+## Batch process
+
+**Summary:** Iterating a single process to external services (e.g. PostgreSQL, Redis, Object Storage, etc)
+should be executed in a **batch-style** in order to reduce connection overheads.
+
+For fetching rows from various tables in a batch-style, please see [Eager Loading](#eager-loading) section.
+
+### Example: Delete multiple files from Object Storage
+
+When you delete multiple files from object storage (e.g. GCS),
+executing a single REST API call multiple times is a quite expensive
+process. Ideally, this should be done in a batch-style, for example, S3 provides
+[batch deletion API](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObjects.html),
+so it'd be a good idea to consider such an approach.
+
+The `FastDestroyAll` module might help this situation. It's a
+small framework when you remove a bunch of database rows and its associated data
+in a batch style.
+
+## Timeout
+
+**Summary:** You should set a reasonable timeout when the system invokes HTTP calls
+to external services (e.g. Kubernetes), and it should be executed in Sidekiq, not
+in Puma/Unicorn threads.
+
+Often, GitLab needs to communicate with an external service such as Kubernetes
+clusters. In this case, it's hard to estimate when the external service finishes
+the requested process, for example, if it's a user-owned cluster that is inactive for some reason,
+GitLab might wait for the response forever ([Example](https://gitlab.com/gitlab-org/gitlab/issues/31475)).
+This could result in Puma/Unicorn timeout and should be avoided at all cost.
+
+You should set a reasonable timeout, gracefully handle exceptions and surface the
+errors in UI or logging internally.
+
+Using [`ReactiveCaching`](https://docs.gitlab.com/ee/development/utilities.html#reactivecaching) is one of the best solutions to fetch external data.
+
+## Keep database transaction minimal
+
+**Summary:** You should avoid accessing to external services (e.g. Gitaly) during database
+transactions, otherwise it leads to severe contention problems
+as an open transaction basically blocks the release of a Postgres backend connection.
+
+For keeping transaction as minimal as possible, please consider using `AfterCommitQueue`
+module or `after_commit` AR hook.
+
+Here is [an example](https://gitlab.com/gitlab-org/gitlab/issues/36154#note_247228859)
+that one request to Gitaly instance during transaction triggered a P1 issue.

-## Buttons
-
-### Button type
-
-Button tags requires a `type` attribute according to the [W3C HTML specification](https://www.w3.org/TR/2011/WD-html5-20110525/the-button-element.html#dom-button-type).
-
-```html
-// bad
-<button></button>
-
-// good
-<button type="button"></button>
-```
-
-### Button role
-
-If an HTML element has an `onClick` handler but is not a button, it should have `role="button"`. This is [more accessible](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/button_role).
-
-```html
-// bad
-<div onClick="doSomething"></div>
-
-// good
-<div role="button" onClick="doSomething"></div>
-```
-
-## Links
-
-### Blank target
-
-Use `rel="noopener noreferrer"` whenever your links open in a new window, i.e. `target="_blank"`. This prevents a security vulnerability [documented by JitBit](https://www.jitbit.com/alexblog/256-targetblank---the-most-underestimated-vulnerability-ever/).
-
-```html
-// bad
-<a href="url" target="_blank"></a>
-
-// good
-<a href="url" target="_blank" rel="noopener noreferrer"></a>
-```
-
-### Fake links
-
-**Do not use fake links.** Use a button tag if a link only invokes JavaScript click event handlers, which is more semantic.
-
-```html
-// bad
-<a class="js-do-something" href="#"></a>
-
-// good
-<button class="js-do-something" type="button"></button>
-```

-# JavaScript style guide
+---

+---
 
-We use [Airbnb's JavaScript Style Guide](https://github.com/airbnb/javascript) and it's accompanying
-linter to manage most of our JavaScript style guidelines.
-
-In addition to the style guidelines set by Airbnb, we also have a few specific rules
-listed below.
-
-> **Tip:**
-You can run eslint locally by running `yarn eslint`
-
-## Avoid forEach
-
-Avoid forEach when mutating data. Use `map`, `reduce` or `filter` instead of `forEach`
-when mutating data. This will minimize mutations in functions,
-which aligns with [Airbnb's style guide](https://github.com/airbnb/javascript#testing--for-real).
-
-```javascript
-// bad
-users.forEach((user, index) => {
-  user.id = index;
-});
-
-// good
-const usersWithId = users.map((user, index) => {
-  return Object.assign({}, user, { id: index });
-});
-```
-
-## Limit number of parameters
-
-If your function or method has more than 3 parameters, use an object as a parameter
-instead.
-
-```javascript
-// bad
-function a(p1, p2, p3) {
-  // ...
-};
-
-// good
-function a(p) {
-  // ...
-};
-```
-
-## Avoid side effects in constructors
-
-Avoid making asynchronous calls, API requests or DOM manipulations in the `constructor`.
-Move them into separate functions instead. This will make tests easier to write and
-code easier to maintain.
-
-```javascript
-// bad
-class myClass {
-  constructor(config) {
-    this.config = config;
-    axios.get(this.config.endpoint)
-  }
-}
-
-// good
-class myClass {
-  constructor(config) {
-    this.config = config;
-  }
-
-  makeRequest() {
-    axios.get(this.config.endpoint)
-  }
-}
-const instance = new myClass();
-instance.makeRequest();
-```
-
-## Avoid classes to handle DOM events
-
-If the only purpose of the class is to bind a DOM event and handle the callback, prefer
-using a function.
-
-```javascript
-// bad
-class myClass {
-  constructor(config) {
-    this.config = config;
-  }
-
-  init() {
-    document.addEventListener('click', () => {});
-  }
-}
-
-// good
-
-const myFunction = () => {
-  document.addEventListener('click', () => {
-    // handle callback here
-  });
-}
-```
-
-## Pass element container to constructor
-
-When your class manipulates the DOM, receive the element container as a parameter.
-This is more maintainable and performant.
-
-```javascript
-// bad
-class a {
-  constructor() {
-    document.querySelector('.b');
-  }
-}
-
-// good
-class a {
-  constructor(options) {
-    options.container.querySelector('.b');
-  }
-}
-```
-
-## Use ParseInt
-
-Use `ParseInt` when converting a numeric string into a number.
-
-```javascript
-// bad
-Number('10')
-
-// good
-parseInt('10', 10);
-```
-
-## CSS Selectors - Use `js-` prefix
-
-If a CSS class is only being used in JavaScript as a reference to the element, prefix
-the class name with `js-`.
-
-```html
-// bad
-<button class="add-user"></button>
-
-// good
-<button class="js-add-user"></button>
-```
-
-## Absolute vs relative paths for modules
-
-Use relative paths if the module you are importing is less than two levels up.
-
-```javascript
-// bad
-import GitLabStyleGuide from '~/guides/GitLabStyleGuide';
-
-// good
-import GitLabStyleGuide from '../GitLabStyleGuide';
-```
-
-If the module you are importing is two or more levels up, use an absolute path instead:
-
-```javascript
-// bad
-import GitLabStyleGuide from '../../../guides/GitLabStyleGuide';
-
-// good
-import GitLabStyleGuide from '~/GitLabStyleGuide';
-```
-
-Additionally, **do not add to global namespace**.
-
-## Do not use `DOMContentLoaded` in non-page modules
-
-Imported modules should act the same each time they are loaded. `DOMContentLoaded`
-events are only allowed on modules loaded in the `/pages/*` directory because those
-are loaded dynamically with webpack.
-
-## Avoid XSS
-
-Do not use `innerHTML`, `append()` or `html()` to set content. It opens up too many
-vulnerabilities.
-
-## Disabling ESLint in new files
-
-Do not disable ESLint when creating new files. Existing files may have existing rules
-disabled due to legacy compatibility reasons but they are in the process of being refactored.
-
-Do not disable specific ESLint rules. Due to technical debt, you may disable the following
-rules only if you are invoking/instantiating existing code modules.
-
-- [no-new](https://eslint.org/docs/rules/no-new)
-- [class-method-use-this](https://eslint.org/docs/rules/class-methods-use-this)
-
-> Note: Disable these rules on a per line basis. This makes it easier to refactor
-> in the future. E.g. use `eslint-disable-next-line` or `eslint-disable-line`.

-# Formatting with Prettier
+---
+redirect_to: '../../fe_guide/tooling.md#formatting-with-prettier'
+---
 
-Our code is automatically formatted with [Prettier](https://prettier.io) to follow our style guides. Prettier is taking care of formatting .js, .vue, and .scss files based on the standard prettier rules. You can find all settings for Prettier in `.prettierrc`.
-
-## Editor
-
-The easiest way to include prettier in your workflow is by setting up your preferred editor (all major editors are supported) accordingly. We suggest setting up prettier to run automatically when each file is saved. Find [here](https://prettier.io/docs/en/editors.html) the best way to set it up in your preferred editor.
-
-Please take care that you only let Prettier format the same file types as the global Yarn script does (.js, .vue, and .scss). In VSCode by example you can easily exclude file formats in your settings file:
-
-```
-  "prettier.disableLanguages": [
-      "json",
-      "markdown"
-  ],
-```
-
-## Yarn Script
-
-The following yarn scripts are available to do global formatting:
-
-```
-yarn prettier-staged-save
-```
-
-Updates all currently staged files (based on `git diff`) with Prettier and saves the needed changes.
-
-```
-yarn prettier-staged
-```
-
-Checks all currently staged files (based on `git diff`) with Prettier and log which files would need manual updating to the console.
-
-```
-yarn prettier-all
-```
-
-Checks all files with Prettier and logs which files need manual updating to the console.
-
-```
-yarn prettier-all-save
-```
-
-Formats all files in the repository with Prettier. (This should only be used to test global rule updates otherwise you would end up with huge MR's).
-
-The source of these Yarn scripts can be found in `/scripts/frontend/prettier.js`.
-
-### Scripts during Conversion period
-
-```
-node ./scripts/frontend/prettier.js check-all ./vendor/
-```
-
-This will go over all files in a specific folder check it.
-
-```
-node ./scripts/frontend/prettier.js save-all ./vendor/
-```
-
-This will go over all files in a specific folder and save it.
-
-## VSCode Settings
-
-### Select Prettier as default formatter
-
-To select Prettier as a formatter, add the following properties to your User or Workspace Settings:
-
-```javascript
-{
-  "[html]": {
-    "editor.defaultFormatter": "esbenp.prettier-vscode"
-  },
-  "[javascript]": {

-  },
-  "[vue]": {
-    "editor.defaultFormatter": "esbenp.prettier-vscode"
-  }
-}
-```
-
-### Format on Save
-
-To automatically format your files with Prettier, add the following properties to your User or Workspace Settings:
-
-```javascript
-{
-  "[html]": {
-    "editor.formatOnSave": true
-  },
-  "[javascript]": {

 Group-level and instance-level endpoints are good to have but are optional.
 
+### Remote hierarchy
+
+Packages are scoped within various levels of access, which is generally configured by setting your remote. A
+remote endpoint may be set at the project level, meaning when installing packages, only packages belonging to that
+project will be visible. Alternatively, a group-level endpoint may be used to allow visibility to all packages
+within a given group. Lastly, an instance-level endpoint can be used to allow visibility to all packages within an

+## Reliably referencing database columns
+
+ActiveRecord by default returns all columns from the queried database table. In some cases the returned rows might need to be customized, for example:
+
+- Specify only a few columns to reduce the amount of data returned from the database.
+- Include columns from `JOIN` relations.
+- Perform calculations (`SUM`, `COUNT`).
+
+In this example we specify the columns, but not their tables:
+
+- `path` from the `projects` table
+- `user_id` from the `merge_requests` table
+
+The query:
+
+```ruby
+# bad, avoid
+Project.select("path, user_id").joins(:merge_requests) # SELECT path, user_id FROM "projects" ...
+```
+
+Later on, a new feature adds an extra column to the `projects` table: `user_id`. During deployment there might be a short time window where the database migration is already executed, but the new version of the application code is not deployed yet. When the query mentioned above executes during this period, the query will fail with the following error message: `PG::AmbiguousColumn: ERROR: column reference "user_id" is ambiguous`
+
+The problem is caused by the way the attributes are selected from the database. The `user_id` column is present in both the `users` and `merge_requests` tables. The query planner cannot decide which table to use when looking up the `user_id` column.
+
+When writing a customized `SELECT` statement, it's better to **explicitly specify the columns with the table name**.
+
+### Good (prefer)
+
+```ruby
+Project.select(:path, 'merge_requests.user_id').joins(:merge_requests)
+
+# SELECT "projects"."path", merge_requests.user_id as user_id FROM "projects" ...
+```
+
+```ruby
+Project.select(:path, :'merge_requests.user_id').joins(:merge_requests)
+
+# SELECT "projects"."path", "merge_requests"."id" as user_id FROM "projects" ...
+```
+
+Example using Arel (`arel_table`):
+
+```ruby
+Project.select(:path, MergeRequest.arel_table[:user_id]).joins(:merge_requests)
+
+# SELECT "projects"."path", "merge_requests"."user_id" FROM "projects" ...
+```
+
+When writing raw SQL query:
+
+```sql
+SELECT projects.path, merge_requests.user_id FROM "projects"...
+```
+
+When the raw SQL query is parameterized (needs escaping):
+
+```ruby
+include ActiveRecord::ConnectionAdapters::Quoting
+
+"""
+SELECT
+  #{quote_table_name('projects')}.#{quote_column_name('path')},
+  #{quote_table_name('merge_requests')}.#{quote_column_name('user_id')}
+FROM ...
+"""
+```
+
+### Bad (avoid)
+
+```ruby
+Project.select('id, path, user_id').joins(:merge_requests).to_sql
+
+# SELECT id, path, user_id FROM "projects" ...
+```
+
+```ruby
+Project.select("path", "user_id").joins(:merge_requests)
+# SELECT "projects"."path", "user_id" FROM "projects" ...
+
+# or
+
+Project.select(:path, :user_id).joins(:merge_requests)
+# SELECT "projects"."path", "user_id" FROM "projects" ...
+```
+
+When a column list is given, ActiveRecord tries to match the arguments against the columns defined in the `projects` table and prepend the table name automatically. In this case, the `id` column is not going to be a problem, but the `user_id` column could return unexpected data:
+
+```ruby
+Project.select(:id, :user_id).joins(:merge_requests)
+
+# Before deployment (user_id is taken from the merge_requests table):
+# SELECT "projects"."id", "user_id" FROM "projects" ...
+
+# After deployment (user_id is taken from the projects table):
+# SELECT "projects"."id", "projects"."user_id" FROM "projects" ...
+```

-### Step 1: Ignoring The Column
+1. Ignoring the column (release M)
+1. Dropping the column (release M+1)
+1. Removing the ignore rule (release M+2)
+
+The reason we spread this out across three releases is that dropping a column is
+a destructive operation that can't be rolled back easily.
+
+Following this procedure helps us to make sure there are no deployments to GitLab.com
+and upgrade processes for self-hosted installations that lump together any of these steps.
+
+### Step 1: Ignoring the column (release M)
 
 The first step is to ignore the column in the application code. This is
 necessary because Rails caches the columns and re-uses this cache in various

+  ignore_column :updated_at, remove_with: '12.7', remove_after: '2019-12-22'

 ```
 
-Once added you should create a _post-deployment_ migration that removes the
-column. Both these changes should be submitted in the same merge request.
+Multiple columns can be ignored, too:
+
+```ruby
+ignore_columns %i[updated_at created_at], remove_with: '12.7', remove_after: '2019-12-22'
+```
+
+We require indication of when it is safe to remove the column ignore with:
+
+- `remove_with`: set to a GitLab release typically two releases (M+2) after adding the
+  column ignore.
+- `remove_after`: set to a date after which we consider it safe to remove the column
+  ignore, typically within the development cycle of release M+2.
+
+This information allows us to reason better about column ignores and makes sure we
+don't remove column ignores too early for both regular releases and deployments to GitLab.com. For
+example, this avoids a situation where we deploy a bulk of changes that include both changes
+to ignore the column and subsequently remove the column ignore (which would result in a downtime).
+
+In this example, the change to ignore the column went into release 12.5.
+
+### Step 2: Dropping the column (release M+1)
+
+Continuing our example, dropping the column goes into a _post-deployment_ migration in release 12.6:
+
+```ruby
+ remove_column :user, :updated_at
+```
+
+### Step 3: Removing the ignore rule (release M+2)
 
-### Step 2: Removing The Ignore Rule
+With the next release, in this example 12.7, we set up another merge request to remove the ignore rule.
+This removes the `ignore_column` line and - if not needed anymore - also the inclusion of `IgnoreableColumns`.
 
-Once the changes from step 1 have been released & deployed you can set up a
-separate merge request that removes the ignore rule. This merge request can
-simply remove the `self.ignored_columns` line.
+This should only get merged with the release indicated with `remove_with` and once
+the `remove_after` date has passed.

+Check the [`production.log`](../administration/logs.md#productionlog)
+on your GitLab server to obtain further details. If you are getting the error like
+`Faraday::ConnectionFailed (execution expired)` in the log, there may be a connectivity issue
+between your GitLab instance and GitHub Enterprise. To verify it, [start the rails console](https://docs.gitlab.com/omnibus/maintenance/#starting-a-rails-console-session)
+and run the commands below replacing `<github_url>` with the URL of your GitHub Enterprise instance:
+
+```ruby
+uri = URI.parse("https://<github_url>") # replace `GitHub-URL` with the real one here
+http = Net::HTTP.new(uri.host, uri.port)
+http.use_ssl = true
+http.verify_mode = 1
+response = http.request(Net::HTTP::Get.new(uri.request_uri))
+```
+
+If you are getting a similar `execution expired` error, it confirms the theory about the
+network connectivity. In that case, make sure that the GitLab server is able to reach your
+GitHub enterprise instance.

+# Vault Authentication with GitLab OpenID Connect
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/issues/22323) in GitLab 9.0
+
+[Vault](https://www.vaultproject.io/) is a secrets management application offered by HashiCorp.
+It allows you to store and manage sensitive information such secret environment variables, encryption keys, and authentication tokens.
+Vault offers Identity-based Access, which means Vault users can authenticate through several of their preferred cloud providers.
+
+In this document, we'll explain how Vault users can authenticate themselves through GitLab by utilizing our OpenID authentication feature.
+The following assumes you already have Vault installed and running.
+
+1. **Get the OpenID Connect client ID and secret from GitLab:**
+
+    First you'll need to create a GitLab application to obtain an application ID and secret for authenticating into Vault. To do this, sign in to GitLab and follow these steps:
+
+    1. On GitLab, click your avatar on the top-right corner, and select your user **Settings > Applications**.
+    1. Fill out the application **Name** and [**Redirect URI**](https://www.vaultproject.io/docs/auth/jwt.html#redirect-uris),
+       making sure to select the **OpenID** scope.
+    1. Save application.
+    1. Copy client ID and secret, or keep the page open for reference.
+    ![GitLab OAuth provider](img/gitlab_oauth_vault_v12_6.png)
+
+1. **Enable OIDC auth on Vault:**
+
+    OpenID Connect is not enabled in Vault by default. This needs to be enabled in the terminal.
+
+    Open a terminal session and run the following command to enable the OpenID Connect authentication provider in Vault:
+
+    ```bash
+    vault auth enable oidc
+    ```
+
+    You should see the following output in the terminal:
+
+    ```bash
+    Success! Enabled oidc auth method at: oidc/
+    ```
+
+1. **Write the OIDC config:**
+
+    Next, Vault needs to be given the application ID and secret generated by GitLab.
+
+    In the terminal session, run the following command to give Vault access to the GitLab application you've just created with an OpenID scope. This allows Vault to authenticate through GitLab.
+
+    Replace `your_application_id` and `your_secret` in the example below with the application ID and secret generated for your app:
+
+    ```bash
+    $ vault write auth/oidc/config \
+        oidc_discovery_url="https://gitlab.com" \
+        oidc_client_id="your_application_id" \
+        oidc_client_secret="your_secret" \
+        default_role="demo" \
+        bound_issuer="localhost"
+    ```
+
+    You should see the following output in the terminal:
+
+    ```bash
+    Success! Data written to: auth/oidc/config
+    ```
+
+1. **Write the OIDC Role Config:**
+
+    Now that Vault has a GitLab application ID and secret, it needs to know the [**Redirect URIs**](https://www.vaultproject.io/docs/auth/jwt.html#redirect-uris) and scopes given to GitLab during the application creation process. The redirect URIs need to match where your Vault instance is running. The `oidc_scopes` field needs to include the `openid`.  Similarly to the previous step, replace `your_application_id` with the generated application ID from GitLab:
+
+    This configuration is saved under the name of the role you are creating. In this case, we are creating a `demo` role. Later, we'll show how you can access this role through the Vault CLI.
+
+    ```bash
+    vault write auth/oidc/role/demo \
+          user_claim="sub" \
+          allowed_redirect_uris="http://localhost:8250/oidc/callback,http://127.0.0.1:8200/ui/vault/auth/oidc/oidc/callback" \
+          bound_audiences="your_application_id" \
+          role_type="oidc" \
+          oidc_scopes="openid" \
+          policies=demo \
+          ttl=1h
+    ```
+
+1. **Sign in to Vault:**
+
+    1. Go to your Vault UI (example: [http://127.0.0.1:8200/ui/vault/auth?with=oidc](http://127.0.0.1:8200/ui/vault/auth?with=oidc)).
+    1. If the `OIDC` method is not currently selected, open the dropdown and select it.
+    1. Click the **Sign in With GitLab** button, which will open a modal window:
+    ![Sign into Vault with GitLab](img/sign_into_vault_with_gitlab_v12_6.png)
+
+    1. Click **Authorize** on the modal to allow Vault to sign in through GitLab. This will redirect you back to your Vault UI as a signed-in user.
+    ![Authorize Vault to connect with GitLab](img/authorize_vault_with_gitlab_v12_6.png)
+
+1. **Sign in using the Vault CLI** (optional):
+
+    Vault also allows you to sign in via their CLI.
+
+    After writing the same configurations from above, you can run the command below in your terminal to sign in with the role configuration created in step 4 above:
+
+    ```bash
+    vault login -method=oidc port=8250 role=demo
+    ```
+
+    Here is a short explaination of what this command does:
+
+    1. In the **Write the OIDC Role Config** (step 4), we created a role called `demo`. We set `role=demo` so Vault knows which configuration we'd like to login in with.
+    1. To set Vault to use the `OIDC` sign-in method, we set `-method=oidc`.
+    1. To set the port that GitLab should redirect to, we set `port=8250` or another port number that matches the port given to GitLab when listing [Redirect URIs](https://www.vaultproject.io/docs/auth/jwt.html#redirect-uris).
+
+    Once you run the command above, it will present a link in the terminal.
+    Click the link in the terminal and a tab will open in the browser confirming you're signed into Vault via OIDC:
+
+    ![Signed into Vault via OIDC](img/signed_into_vault_via_oidc_v12_6.png)
+
+    The terminal will output:
+
+    ```
+    Success! You are now authenticated. The token information displayed below
+    is already stored in the token helper. You do NOT need to run "vault login"
+    again. Future Vault requests will automatically use this token.
+    ```

 This will not use the SSH Agent and requires at least Git 2.10.
 
+## Multiple accounts on a single GitLab instance
+
+The [per-repository](#per-repository-ssh-keys) method also works for using
+multiple accounts within a single GitLab instance.
+
+Alternatively, it is possible to directly assign aliases to hosts in
+`~.ssh/config`. SSH and, by extension, Git will fail to log in if there is
+an `IdentityFile` set outside of a `Host` block in `.ssh/config`. This is
+due to how SSH assembles `IdentityFile` entries and is not changed by
+setting `IdentitiesOnly` to `yes`. `IdentityFile` entries should point to
+the private key of an SSH key pair.
+
+NOTE: **Note:**
+Private and public keys should be readable by the user only. Accomplish this
+on Linux and macOS by running: `chmod 0400 ~/.ssh/<example_ssh_key>` and
+`chmod 0400 ~/.ssh/<example_sh_key.pub>`.
+
+```conf
+# User1 Account Identity
+Host <user_1.gitlab.com>
+  Hostname gitlab.com
+  PreferredAuthentications publickey
+  IdentityFile ~/.ssh/<example_ssh_key1>
+
+# User2 Account Identity
+Host <user_2.gitlab.com>
+  Hostname gitlab.com
+  PreferredAuthentications publickey
+  IdentityFile ~/.ssh/<example_ssh_key2>
+```
+
+NOTE: **Note:**
+The example `Host` aliases are defined as `user_1.gitlab.com` and
+`user_2.gitlab.com` for efficiency and transparency. Advanced configurations
+are more difficult to maintain; using this type of alias makes it easier to
+understand when using other tools such as `git remote` subcommands. SSH
+would understand any string as a `Host` alias thus `Tanuki1` and `Tanuki2`,
+despite giving very little context as to where they point, would also work.
+
+Cloning the `gitlab` repository normally looks like this:
+
+```sh
+git clone git@gitlab.com:gitlab-org/gitlab.git
+```
+
+To clone it for `user_1`, replace `gitlab.com` with the SSH alias `user_1.gitlab.com`:
+
+```sh
+git clone git@<user_1.gitlab.com>:gitlab-org/gitlab.git
+```
+
+Fix a previously cloned repository using the `git remote` command.
+
+The example below assumes the remote repository is aliased as `origin`.
+
+```sh
+git remote set-url origin git@<user_1.gitlab.com>:gitlab-org/gitlab.git
+```

+#### CI pipeline minutes
+
+CI pipeline minutes are the execution time for your [pipelines](../ci/pipelines.md) on our shared runners. Each [GitLab.com tier](https://about.gitlab.com/pricing/) includes a monthly quota of CI pipeline minutes. The quota is applied per group, shared across all members of that group, its subgroups and nested projects. To view the usage, navigate to the group's page, then **Settings > Usage Quotas**.
+
+Only pipeline minutes for our shared runners are restricted. If you have a specific runner setup for your projects, there is no limit to your build time on GitLab.com.
+
+The minutes limit only applies to private projects. The available quota is reset on the first of each calendar month at midnight UTC.
+
+If you reach your limit, you can [purchase additional CI minutes](#extra-shared-runners-pipeline-minutes), or upgrade your account to [Silver or Gold](https://about.gitlab.com/pricing/). Note, your own runners can still be used even if you reach your limits.
+
+##### How pipeline quota usage is calculated
+
+Pipeline quota usage is calculated as the sum of the duration of each individual job. This is slightly different to how pipeline _duration_ is [calculated](https://docs.gitlab.com/ee/ci/pipelines.html#how-pipeline-duration-is-calculated). Pipeline quota usage doesn't consider the intersection of jobs.
+
+A simple example is:
+
+A (1, 3)
+B (2, 4)
+C (6, 7)
+
+In the example:
+
+A begins at 1 and ends at 3.
+B begins at 2 and ends at 4.
+C begins at 6 and ends at 7.
+Visually, it can be viewed as:
+
+```
+0  1  2  3  4  5  6  7
+   AAAAAAA
+      BBBBBBB
+                  CCCC
+```
+
+The sum of each individual job is being calculated therefore in this example, `8` runner minutes would be used for this pipeline:
+
+```
+A + B + C = 3 + 3 + 2 => 8
+```
+
 #### Extra Shared Runners pipeline minutes

+## Overview
+
+GitLab administrators are responsible for the overall security of their instance. To assist, GitLab provides a Credentials inventory to keep track of all the credentials that can be used to access their self-managed instance.
+
+Using Credentials inventory, GitLab administrators can see all the personal access tokens and SSH keys that exist in their instance and:
+
+- Who they belong to.
+- Their access scope.
+- Their usage pattern.
+
+To access the Credentials inventory, navigate to **Admin Area > Credentials**.

+## Limiting lifetime of personal access tokens **(ULTIMATE ONLY)**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/3649) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.6.
+
+Users can optionally specify an expiration date for
+[personal access tokens](../../profile/personal_access_tokens.md).
+This expiration date is not a requirement, and can be set to any arbitrary date.
+
+Since personal access tokens are the only token needed for programmatic access to GitLab,
+organizations with security requirements may want to enforce more protection to require
+regular rotation of these tokens.
+
+### Setting a limit
+
+Only a GitLab administrator can set a limit. Leaving it empty means
+there are no restrictions.
+
+To set a limit on how long personal access tokens are valid:
+
+1. Navigate to **Admin Area > Settings > General**.
+1. Expand the **Account and limit** section.
+1. Fill in the **Maximun allowable lifetime for personal access tokens (days)** field.
+1. Click **Save changes**.
+
+Once a lifetime for personal access tokens is set, GitLab will:
+
+- Apply the lifetime for new personal access tokens, and require users to set an expiration date
+  and a date no later than the allowed lifetime.
+- After three hours, revoke old tokens with no expiration date or with a lifetime longer than the
+  allowed lifetime. Three hours is given to allow administrators to change the allowed lifetime,
+  or remove it, before revocation takes place.

+# Security Configuration **(ULTIMATE)**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/merge_requests/20711) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.6.
+
+## Overview
+
+The security configuration page displays the configuration state of each of the security
+features and can be accessed through a project's sidebar nav.
+
+![Screenshot of security configuration page](../img/security_configuration_page_v12_6.png)
+
+The page uses the project's latest default branch [CI pipeline](../../../ci/pipelines.md) to determine the configuration
+state of each feature. If a job with the expected security report artifact exists in the pipeline,
+the feature is considered configured.
+
+NOTE: **Note:** if the latest pipeline used [Auto DevOps](../../../topics/autodevops/index.md),
+all security features will be configured by default.
+
+## Limitations
+
+It is not possible to enable or disable a feature using the configuration page.
+However, instructions on how to enable or disable a feature can be found through
+the links next to each feature on that page.

+## Install using GitLab CI (alpha)
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/merge_requests/20822) in GitLab 12.6.
+
+CAUTION: **Warning:**
+This is an _alpha_ feature, and it is subject to change at any time without
+prior notice.
+
+This alternative method allows users to install GitLab-managed
+applications using GitLab CI. It also allows customization of the
+install using Helm `values.yaml` files.
+
+Supported applications:
+
+- [Ingress](#install-ingress-using-gitlab-ci)
+- [Sentry](#install-sentry-using-gitlab-ci)
+
+### Usage
+
+To install applications using GitLab CI:
+
+1. Connect the cluster to a [cluster management project](management_project.md).
+1. In that project, add a `.gitlab-ci.yml` file with the following content:
+
+    ```yaml
+    include:
+      - template: Managed-Cluster-Applications.gitlab-ci.yml
+    ```
+
+1. Add a `.gitlab/managed-apps/config.yaml` file to define which
+  applications you would like to install. Define the `installed` key as
+  `true` to install the application and `false` to uninstall the
+  application. For example, to install Ingress:
+
+    ```yaml
+    ingress:
+      installed: true
+    ```
+
+1. Optionally, define `.gitlab/managed-apps/<application>/values.yaml` file to
+   customize values for the installed application.
+
+A GitLab CI pipeline will then run on the `master` branch to install the
+applications you have configured.
+
+### Install Ingress using GitLab CI
+
+To install Ingress, define the `.gitlab/managed-apps/config.yaml` file
+with:
+
+```yaml
+ingress:
+  installed: true
+```
+
+Ingress will then be installed into the `gitlab-managed-apps` namespace
+of your cluster.
+
+You can customize the installation of Ingress by defining
+`.gitlab/managed-apps/ingress/values.yaml` file in your cluster
+management project. Refer to the
+[chart](https://github.com/helm/charts/tree/master/stable/nginx-ingress)
+for the available configuration options.
+
+### Install Sentry using GitLab CI
+
+NOTE: **Note:**
+The Sentry Helm chart [recommends](https://github.com/helm/charts/blob/f6e5784f265dd459c5a77430185d0302ed372665/stable/sentry/values.yaml#L284-L285) at least 3GB of available RAM for database migrations.
+
+To install Sentry, define the `.gitlab/managed-apps/config.yaml` file
+with:
+
+```yaml
+sentry:
+  installed: true
+```
+
+Sentry will then be installed into the `gitlab-managed-apps` namespace
+of your cluster.
+
+You can customize the installation of Sentry by defining
+`.gitlab/managed-apps/sentry/values.yaml` file in your cluster
+management project. Refer to the
+[chart](https://github.com/helm/charts/tree/master/stable/sentry)
+for the available configuration options.
+
+We recommend you pay close attention to the following configuration options:
+
+- `email`. Needed to invite users to your Sentry instance and to send error emails.
+- `user`. Where you can set the login credentials for the default admin user.
+- `postgresql`. For a PostgreSQL password that can be used when running future updates.
+
+NOTE: **Note:**
+When upgrading it is important to provide the existing PostgreSQL password (given using the `postgresql.postgresqlPassword` key) or you will receive authentication errors. See the [PostgreSQL chart documentation](https://github.com/helm/charts/tree/master/stable/postgresql#upgrade) for more information.
+
+Here is an example configuration for Sentry:
+
+```yaml
+# Admin user to create
+user:
+  # Indicated to create the admin user or not,
+  # Default is true as the initial installation.
+  create: true
+  email: "<your email>"
+  password: "<your password>"
+
+email:
+  from_address: "<your from email>"
+  host: smtp
+  port: 25
+  use_tls: false
+  user: "<your email username>"
+  password: "<your email password>"
+  enable_replies: false
+
+ingress:
+  enabled: true
+  hostname: "<sentry.example.com>"
+
+# Needs to be here between runs.
+# See https://github.com/helm/charts/tree/master/stable/postgresql#upgrade for more info
+postgresql:
+  postgresqlPassword: example-postgresql-password

 SAML on GitLab.com allows users to be automatically added to a group, and then allows those users to sign into GitLab.com. Users should already have an account on the GitLab instance, or can create one when logging in for the first time.
 
 User synchronization for GitLab.com is partially supported using [SCIM](scim_setup.md).
 
-NOTE: **Note:**
-SAML SSO for GitLab.com groups does not sync users between providers without using SCIM. If a group is not using SCIM, group Owners will still need to manage user accounts (for example, removing users when necessary).

 When testing the connection, you may encounter an error: **You appear to have entered invalid credentials. Please confirm you are using the correct information for an administrative account**. If `Tenant URL` and `secret token` are correct, check whether your group path contains characters that may be considered invalid JSON primitives (such as `.`). Removing such characters from the group path typically resolves the error.

-## Example code
+## How To
+
+In this section, we show you how to build on the basic example to:
+
+- Run the function locally.
+- Set up secret variables.
+- Set up CORS.
+
+### Running function locally
+
+The `serverless-offline` plugin allows to run your code locally. To run your code locally:
+
+1. Add the following to your `serverless.yml`:
+
+   ```yaml
+   plugins:
+     - serverless-offline
+   ```
+
+1. Start the service by running the following command:
+
+   ```shell
+   serverless offline
+   ```
+
+Running the following `curl` command should trigger your function.
+
+```sh
+curl http://localhost:3000/hello
+```
+
+It should output:
+
+```json
+{
+  "message": "Your function executed successfully!"
+}
+```
+
+### Secret variables
+
+Secrets are injected into your functions using environment variables.
+
+By defining variables in the provider section of the `serverless.yml`, you add them to
+the environment of the deployed function:
+
+```yaml
+provider:
+  ...
+  environment:
+    A_VARIABLE: ${env:A_VARIABLE}
+```
+
+From there, you can reference them in your functions as well.
+Remember to add `A_VARIABLE` to your GitLab CI variables under **Settings > CI/CD > Variables**, and it will get picked up and deployed with your function.
+
+NOTE: **Note:**
+Anyone with access to the AWS environemnt may be able to see the values of those
+variables persisted in the lambda definition.
+
+### Setting up CORS
+
+If you want to set up a web page that makes calls to your function, like we have done in the [template](https://gitlab.com/gitlab-org/project-templates/serverless-framework/), you need to deal with the Cross-Origin Resource Sharing (CORS).
+
+The quick way to do that is to add the `cors: true` flag to the HTTP endpoint in your `serverless.yml`:
+
+```yaml
+functions:
+  hello:
+    handler: src/handler.hello
+    events:
+      - http: # Rewrite this part to enable CORS
+          path: hello
+          method: get
+          cors: true # <-- CORS here
+```
+
+You also need to return CORS specific headers in your function response:
+
+```javascript
+'use strict';
+
+module.exports.hello = async event => {
+  return {
+    statusCode: 200,
+    headers: {
+      // Uncomment the line below if you need access to cookies or authentication
+      // 'Access-Control-Allow-Credentials': true,
+      'Access-Control-Allow-Origin': '*'
+    },
+    body: JSON.stringify(
+      {
+        message: 'Your function executed successfully!'
+      },
+      null,
+      2
+    ),
+  };
+};
+```
+
+For more information, see the [Your CORS and API Gateway survival guide](https://serverless.com/blog/cors-api-gateway-survival-guide/)
+blog post written by the Serverless Framework team.
+
+### Writing automated tests
+
+The [Serverless Framework](https://gitlab.com/gitlab-org/project-templates/serverless-framework/)
+example project shows how to use Jest, Axios, and `serverless-offline` plugin to do
+automated testing of both local and deployed serverless function.

+The body of an MR contains its description, along with its widget (displaying information

+collaborating with that MR.
+
+MRs also contain navigation tabs from which you can see the discussion happening on the thread,

+So far, the navigation tabs present in merge requests to display **Discussion**,

+widget.

+To facilitate this navigation without having to scroll up and down through the page
+to find these tabs, based on user feedback, we are experimenting with a new positioning
+of these tabs. They are now located at the top of the merge request, with a new
+**Overview** tab, containing the description of the merge request followed by the
+widget. Next to **Overview**, you can find **Pipelines**, **Commits**, and **Changes**.
