# grpc-tools
This package distributes the Protocol Buffers compiler `protoc` along with the
plugin for generating client and service objects for use with the Node gRPC
libraries.
## Usage
This library exports the `grpc_tools_node_protoc` executable, which accepts all
of the same arguments as `protoc` itself. For use with Node, you most likely
want to use CommonJS-style imports. An example of generating code this way can
be found in [this guide](https://github.com/protocolbuffers/protobuf-javascript/blob/main/docs/index.md).
The `grpc_tools_node_protoc` automatically includes the Node gRPC plugin, so
it also accepts the `--grpc_out=[option:]path` argument. The option can be
one of the following:
- `grpc_js`: Generates code with `require('@grpc/grpc-js')` instead of
`require('grpc')`
- `generate_package_definition`: Generates code that does not `require` any
gRPC library, and instead generates `PackageDefinition` objects that can
be passed to the `loadPackageDefinition` function provided by both the
`grpc` and `@grpc/grpc-js` libraries.
