# Nanopb: Bazel build
The Bazel build system, is designed to be fast and correct. Nanopb provides a
set of plugins for the Bazel build system allowing Nanopb to be integrated
into the build.
## Getting started
Add the following to your WORKSPACE file.
``` py
# WORKSPACE
git_repository(
name = "com_github_nanopb_nanopb",
remote = "https://github.com/nanopb/nanopb.git"
commit = "<TODO:Enter your desired commit>",
)
load("@com_github_nanopb_nanopb//extra/bazel:nanopb_deps.bzl", "nanopb_deps")
nanopb_deps()
load("@com_github_nanopb_nanopb//extra/bazel:python_deps.bzl",
"nanopb_python_deps")
nanopb_python_deps()
load("@com_github_nanopb_nanopb//extra/bazel:nanopb_workspace.bzl",
"nanopb_workspace")
nanopb_workspace()
```
To use the Nanopb rules with in your build you can use the
`cc_nanopb_proto_library` which works in a similar way to the native
`cc_proto_library` rule.
``` py
# BUILD.bazel
load("@com_github_nanopb_nanopb//extra/bazel:nanopb_cc_proto_library.bzl",
"nanopb_cc_proto_library")
# Your native proto_library.
proto_library(
name = "descriptor",
srcs = [
"generator/proto/google/protobuf/descriptor.proto",
],
)
# Generated library.
cc_nanopb_proto_library(
name = "descriptor_nanopb",
protos = [":descriptor"],
visibility = ["//visibility:private"],
)
# Depend directly on the generated code using a cc_library.
cc_library(
name = "uses_generated_descriptors",
deps = [":descriptor_nanopb"],
hdrs = ["my_header.h"],
)
```
If you have a custom nanopb options file, use the `nanopb_options_files` argument shown below.
``` py
# Generated library with options.
cc_nanopb_proto_library(
name = "descriptor_nanopb",
protos = [":descriptor"],
nanopb_options_files = ["descriptor.options"],
visibility = ["//visibility:private"],
)
```
