ts-protoc-gen

A protoc plugin for generating TypeScript declarations and service definitions from Protocol Buffers (proto3). Version 0.15.0 is the latest stable release. It works alongside protoc to produce .ts files (including gRPC service stubs) and has been widely used but is now in maintenance mode, with alternatives like protobuf-ts or buf's protoc-gen-es recommended. Key differentiator: direct integration with protoc for TypeScript/JavaScript projects.
