    Generate Typescript definitions for type safe gRPC with a modern API

    A fork of grpc_tools_node_protoc_ts

    This package is under active development and feedback is appreciated

    What is this?

    This package generates Typescript definitions for the Javascript protos produced by the (poorly documented) grpc-tools npm package.

    Why would I use this?

    If you want to use protos and gRPC in Javascript code, you could use the @grpc/proto-loader package. It parses the protos to Javacript at runtime. If you need flexibily, this may be the best option. However, if you've gotten this far, you're probably looking for type safety, and for that we need to generate code.

    grpc-tools includes a binary (protoc) and plugin to generate Node implementations of protos, and this package is a plugin for protoc which generates Typescript definitions for those implementations.

    How do I use this?

    Follow the example app!


    The Javascript protobuf implementations generated by grpc-tools use a callback pattern. Unfortunately, this code doesn't fit in well with modern async/await code.

    To get a Promise API you may use the grpc-promise-ts package. It's still under development, but currently can convert the gRPC client produced by grpc-tools into a client with a Promise API. The Typescript definitions produced by this package include the Promise Client (optionally they can be supressed).
