NodeJs Rules

Rule	Description
node_proto_repositories	Load workspace dependencies.
node_proto_compile	Generate node js protobuf source files.
node_proto_library	Generate a node module packaged with protobuf sources.

node_proto_repositories

Enable node support by loading the dependencies in your workspace.

This should occur after loading rules_node. See the WORKSPACE file for the appropriate commit to use from that repo.

load("@org_pubref_rules_protobuf//node:rules.bzl", "node_proto_repositories")
node_proto_repositories()

node_proto_compile

This is a thin wrapper over the proto_compile rule having language @org_pubref_rules_protobuf//node (common js output of the --js_out protoc option.

load("@org_pubref_rules_protobuf//node:rules.bzl", "node_proto_compile")

node_proto_compile(
  name = "protos",
  protos = ["message.proto"],
  with_grpc = True,
)

$ bazel build :protos
Target //:protos up-to-date:
  bazel-genfiles/message_pb.js
  bazel-genfiles/message_grpc_pb.js

node_proto_library

Load the requisite external node modules via the yarn_modules repository rule in your WORKSPACE:

# WORKSPACE
load("@org_pubref_rules_node//node:rules.bzl", "yarn_modules")

yarn_modules(
    name = "yarn_modules",
    deps = {
        "google-protobuf": "3.4.0",
        "grpc": "1.6.0"
    },
)

Then, in your BUILD file:

load("@org_pubref_rules_node//node:rules.bzl", "node_binary")
load("//node:rules.bzl", "node_proto_library")

node_proto_library(
    name = "api",
    protos = ["api.proto"],
    verbose = 0,
    with_grpc = True,
)

node_binary(
    name = "server",
    main = "server.js",
    deps = [
        ":api",
        "@yarn_modules//:_all_",
    ],
)
