# Protobuf & gRPC Stub Generator

Compiles Protocol Buffer definitions into language-specific gRPC client and server stubs using buf CLI and protoc plugins. Validates proto files against Buf lint rules and detects breaking changes.

## Installation

Use the upstream install or setup path that matches your environment:
- npm package: [@grpc/grpc-js](https://www.npmjs.com/package/@grpc/grpc-js)
- npm package: [grpc](https://www.npmjs.com/package/grpc).
- npm package: [@grpc/proto-loader](https://www.npmjs.com/package/@grpc/proto-loader)
- npm package: [grpc-tools](https://www.npmjs.com/package/grpc-tools)

Requirements and caveats from upstream:
- # gRPC on Node.js
- For a comparison of the features available in these two libraries, see [this document](https://github.com/grpc/grpc-node/tree/master/PACKAGE-COMPARISON.md)
- Directory: [packages/grpc-js](https://github.com/grpc/grpc-node/tree/master/packages/grpc-js)
