protoc-gen-grpc-js

A protoc plugin that generates gRPC client and server service definitions for Node.js from Protocol Buffers. Version 0.4.0 targets gRPC-js (not grpc) and requires google-protobuf ^3.14.0. Outputs TypeScript-compatible JavaScript modules (ESM/CJS). Different from grpc-tools in that it generates idiomatic JS/TS service objects compatible with the @grpc/grpc-js library. Release cadence is irregular, currently stable but may have breaking changes before 1.0.
