JavaScript

Rules for generating JavaScript protobuf, gRPC-node and gRPC-Web .js and .d.ts files using standard Protocol Buffers and gRPC.

Note

You must add the required dependencies to your package.json file:

"dependencies": {
  "@grpc/grpc-js": "1.3.7",
  "google-protobuf": "3.18.0",
  "grpc-tools": "1.11.2",
  "grpc-web": "1.2.1",
  "ts-protoc-gen": "0.15.0"
}

Name

Type

Mandatory

Default

Description

protos

label_list

true

List of labels that provide the ProtoInfo provider (such as proto_library from rules_proto)

options

string_list_dict

false

[]

Extra options to pass to plugins, as a dict of plugin label -> list of strings. The key * can be used exclusively to apply to all plugins

verbose

int

false

0

The verbosity level. Supported values and results are 0: Show nothing, 1: Show command, 2: Show command and sandbox after running protoc, 3: Show command and sandbox before and after running protoc, 4. Show env, command, expected outputs and sandbox before and after running protoc

prefix_path

string

false

""

Path to prefix to the generated files in the output directory

extra_protoc_args

string_list

false

[]

A list of extra args to pass directly to protoc, not as plugin options

extra_protoc_files

label_list

false

[]

List of labels that provide extra files to be available during protoc execution

output_mode

string

false

PREFIXED

The output mode for the target. PREFIXED (the default) will output to a directory named by the target within the current package root, NO_PREFIX will output directly to the current package. Using NO_PREFIX may lead to conflicting writes
