Protoc Gen Typescript

Compile .proto files to plain TypeScript. Supports gRPC Node and gRPC Web.

Note

As of 2024, this project has adopted Rust as its primary programming language, replacing JavaScript. See the issue for the details.

Contributing

I have limited availability to consistently maintain this project, as my time is primarily allocated to cutting new releases and implementing fixes on an ad hoc basis.
