npm-config(1) -- Manage the npm configuration file
==================================================
## SYNOPSIS
npm config set <key> <value> [--global]
npm config get <key>
npm config delete <key>
npm config list
npm config edit
npm get <key>
npm set <key> <value> [--global]
## DESCRIPTION
npm gets its configuration values from 6 sources, in this priority:
### Command Line Flags
Putting `--foo bar` on the command line sets the
`foo` configuration parameter to `"bar"`. A `--` argument tells the cli
parser to stop reading flags. A `--flag` parameter that is at the *end* of
the command will be given the value of `true`.
### Environment Variables
Any environment variables that start with `npm_config_` will be interpreted
as a configuration parameter. For example, putting `npm_config_foo=bar` in
your environment will set the `foo` configuration parameter to `bar`. Any
environment configurations that are not given a value will be given the value
of `true`. Config values are case-insensitive, so `NPM_CONFIG_FOO=bar` will
work the same.
### Per-user config file
`$HOME/.npmrc` (or the `userconfig` param, if set above)
This file is an ini-file formatted list of `key = value` parameters.
### Global config file
`$PREFIX/etc/npmrc` (or the `globalconfig` param, if set above):
This file is an ini-file formatted list of `key = value` parameters
### Built-in config file
`path/to/npm/itself/npmrc`
This is an unchangeable "builtin"
configuration file that npm keeps consistent across updates. Set
fields in here using the `./configure` script that comes with npm.
This is primarily for distribution maintainers to override default
configs in a standard and consistent manner.
### Default Configs
A set of configuration parameters that are internal to npm, and are
defaults if nothing else is specified.
## Sub-commands
Config supports the following sub-commands:
### set
npm config set key value
Sets the config key to the value.
If value is omitted, then it sets it to "true".
### get
npm config get key
Echo the config value to stdout.
### list
npm config list
Show all the config settings.
### delete
npm config delete key
Deletes the key from all configuration files.
### edit
npm config edit
Opens the config file in an editor. Use the `--global` flag to edit the
global config.
## Shorthands and Other CLI Niceties
The following shorthands are parsed on the command-line:
* `-v`: `--version`
* `-h`, `-?`, `--help`, `-H`: `--usage`
* `-s`, `--silent`: `--loglevel silent`
* `-q`, `--quiet`: `--loglevel warn`
* `-d`: `--loglevel info`
* `-dd`, `--verbose`: `--loglevel verbose`
* `-ddd`: `--loglevel silly`
* `-g`: `--global`
* `-l`: `--long`
* `-m`: `--message`
* `-p`, `--porcelain`: `--parseable`
* `-reg`: `--registry`
* `-v`: `--version`
* `-f`: `--force`
* `-l`: `--long`
* `-desc`: `--description`
* `-S`: `--save`
* `-D`: `--save-dev`
* `-O`: `--save-optional`
* `-y`: `--yes`
* `-n`: `--yes false`
* `ll` and `la` commands: `ls --long`
If the specified configuration param resolves unambiguously to a known
configuration parameter, then it is expanded to that configuration
parameter. For example:
npm ls --par
# same as:
npm ls --parseable
If multiple single-character shorthands are strung together, and the
resulting combination is unambiguously not some other configuration
param, then it is expanded to its various component pieces. For
example:
npm ls -gpld
# same as:
npm ls --global --parseable --long --loglevel info
## Per-Package Config Settings
When running scripts (see `npm-scripts(1)`)
the package.json "config" keys are overwritten in the environment if
there is a config param of `<name>[@<version>]:<key>`. For example, if
the package.json has this:
{ "name" : "foo"
, "config" : { "port" : "8080" }
, "scripts" : { "start" : "node server.js" } }
and the server.js is this:
http.createServer(...).listen(process.env.npm_package_config_port)
then the user could change the behavior by doing:
npm config set foo:port 80
## Config Settings
### always-auth
* Default: false
* Type: Boolean
Force npm to always require authentication when accessing the registry,
even for `GET` requests.
### bin-publish
* Default: false
* Type: Boolean
If set to true, then binary packages will be created on publish.
This is the way to opt into the "bindist" behavior described below.
### bindist
* Default: Unstable node versions, `null`, otherwise
`"<node version>-<platform>-<os release>"`
* Type: String or `null`
Experimental: on stable versions of node, binary distributions will be
created with this tag. If a user then installs that package, and their
`bindist` tag is found in the list of binary distributions, they will
get that prebuilt version.
Pre-build node packages have their preinstall, install, and postinstall
scripts stripped (since they are run prior to publishing), and do not
have their `build` directories automatically ignored.
It's yet to be seen if this is a good idea.
### browser
* Default: OS X: `"open"`, others: `"google-chrome"`
* Type: String
The browser that is called by the `npm docs` command to open websites.
### ca
* Default: The npm CA certificate
* Type: String or null
The Certificate Authority signing certificate that is trusted for SSL
connections to the registry.
Set to `null` to only allow "known" registrars, or to a specific CA cert
to trust only that specific signing authority.
See also the `strict-ssl` config.
### cache
* Default: Windows: `%APPDATA%\npm-cache`, Posix: `~/.npm`
* Type: path
The location of npm's cache directory. See `npm-cache(1)`
### cache-max
* Default: Infinity
* Type: Number
The maximum time (in seconds) to keep items in the registry cache before
re-checking against the registry.
Note that no purging is done unless the `npm cache clean` command is
explicitly used, and that only GET requests use the cache.
### cache-min
* Default: 0
* Type: Number
The minimum time (in seconds) to keep items in the registry cache before
re-checking against the registry.
Note that no purging is done unless the `npm cache clean` command is
explicitly used, and that only GET requests use the cache.
### color
* Default: true on Posix, false on Windows
* Type: Boolean or `"always"`
If false, never shows colors. If `"always"` then always shows colors.
If true, then only prints color codes for tty file descriptors.
### coverage
* Default: false
* Type: Boolean
A flag to tell test-harness to run with their coverage options enabled,
if they respond to the `npm_config_coverage` environment variable.
### depth
* Default: Infinity
* Type: Number
The depth to go when recursing directories for `npm ls` and
`npm cache ls`.
### description
* Default: true
* Type: Boolean
Show the description in `npm search`
### dev
* Default: false
* Type: Boolean
Install `dev-dependencies` along with packages.
Note that `dev-dependencies` are also installed if the `npat` flag is
set.
### editor
* Default: `EDITOR` environment variable if set, or `"vi"` on Posix,
or `"notepad"` on Windows.
* Type: path
The command to run for `npm edit` or `npm config edit`.
### force
* Default: false
* Type: Boolean
Makes various commands more forceful.
* lifecycle script failure does not block progress.
* publishing clobbers previously published versions.
* skips cache when requesting from the registry.
* prevents checks against clobbering non-npm files.
### git
* Default: `"git"`
* Type: String
The command to use for git commands. If git is installed on the
computer, but is not in the `PATH`, then set this to the full path to
the git binary.
### global
* Default: false
* Type: Boolean
Operates in "global" mode, so that packages are installed into the
`prefix` folder instead of the current working directory. See
`npm-folders(1)` for more on the differences in behavior.
* packages are installed into the `prefix/node_modules` folder, instead of the
current working directory.
* bin files are linked to `prefix/bin`
* man pages are linked to `prefix/share/man`
### globalconfig
* Default: {prefix}/etc/npmrc
* Type: path
The config file to read for global config options.
### globalignorefile
* Default: {prefix}/etc/npmignore
* Type: path
The config file to read for global ignore patterns to apply to all users
and all projects.
If not found, but there is a "gitignore" file in the
same directory, then that will be used instead.
### group
* Default: GID of the current process
* Type: String or Number
The group to use when running package scripts in global mode as the root
user.
### https-proxy
* Default: the `HTTPS_PROXY` or `https_proxy` or `HTTP_PROXY` or
`http_proxy` environment variables.

A proxy to use for outgoing https requests.
### user-agent
* Default: npm/{npm.version} node/{process.version}
* Type: String
Sets a User-Agent to the request header
### ignore
* Default: ""
* Type: string
A white-space separated list of glob patterns of files to always exclude
from packages when building tarballs.
### init.version
* Default: "0.0.0"
* Type: semver
The value `npm init` should use by default for the package version.
### init.author.name
* Default: ""
* Type: String
The value `npm init` should use by default for the package author's name.
### init.author.email
* Default: ""
* Type: String
The value `npm init` should use by default for the package author's email.
### init.author.url
* Default: ""
* Type: String
The value `npm init` should use by default for the package author's homepage.
### json
* Default: false
* Type: Boolean
Whether or not to output JSON data, rather than the normal output.
This feature is currently experimental, and the output data structures
for many commands is either not implemented in JSON yet, or subject to
change. Only the output from `npm ls --json` is currently valid.
### link
* Default: false
* Type: Boolean
If true, then local installs will link if there is a suitable globally
installed package.
Note that this means that local installs can cause things to be
installed into the global space at the same time. The link is only done
if one of the two conditions are met:
* The package is not already installed globally, or
* the globally installed version is identical to the version that is
being installed locally.

* Values: "silent", "win", "error", "warn", "http", "info", "verbose", "silly"
What level of logs to report. On failure, *all* logs are written to
`npm-debug.log` in the current working directory.
Any logs of a higher level than the setting are shown.
The default is "http", which shows http, warn, and error output.
### logprefix

* Type: Boolean
Whether or not to prefix log messages with "npm" and the log level. See
also "color" and "loglevel".

* Type: path
A node module to `require()` when npm loads. Useful for programmatic
usage.

* Type: Number or Stream
Where to write "normal" output. This has no effect on log output.
### parseable
* Default: false
* Type: Boolean
Output parseable results from commands that write to
standard output.
