@protobuf-ts/protoc
===================
Installs the protocol buffer compiler "protoc" for you.
Installation (not necessary if you use the [protobuf-ts plugin](https://github.com/timostamm/protobuf-ts/tree/master/packages/plugin)):
```shell script
# with npm:
npm install @protobuf-ts/protoc
# with yarn:
yarn add @protobuf-ts/protoc
```
Now you can run protoc as usual, you just have to prefix your command with
`npx` or `yarn`:
```shell script
# with npm:
npx protoc --version
# with yarn:
yarn protoc --version
```
If you do not already have protoc in your `$PATH`, this will automatically
download the latest release of protoc for your platform from the github
release page, then run the executable with your arguments.
#### Yarn berry
This package is not compatible with Yarn berry. Please use
[node-protoc](https://www.npmjs.com/package/node-protoc).
#### Installing a specific version
Add the following to your package json:
```
"config": {
"protocVersion": "3.11.0"
}
```
#### Prevent using protoc from `$PATH`
Add a `protocVersion` to your package json, see above.
#### Added arguments
The script passes all given arguments to protoc and adds the
following arguments:
1. `--proto_path` that points to the `include/` directory of the
downloaded release (skipped when found on `$PATH`)
2. `--plugin` argument for all plugins found in `node_modules/.bin/`
3. `--proto_path` argument for `node_modules/@protobuf-ts/plugin`
