ts-proto

ts-proto transforms your .proto files into strongly-typed, idiomatic TypeScript type definitions!

Overview

ts-proto generates TypeScript types from protobuf schemas.

I.e. given a person.proto schema like:

message Person {
  string name = 1;
}

ts-proto will generate a person.ts file like:

interface Person {
  name?: string
}

QuickStart

• npm install ts-proto
• protoc --plugin=./node_modules/.bin/protoc-gen-ts_proto --ts_proto_out=. ./simple.proto
  • (Note that the output parameter name, ts_proto_out, is named based on the suffix of the plugin's name, i.e. "ts_proto" suffix in the --plugin=./node_modules/.bin/protoc-gen-ts_proto parameter becomes the _out prefix, per protoc's CLI conventions.)
  • On Windows, use protoc --plugin=protoc-gen-ts_proto=.\node_modules\.bin\protoc-gen-ts_proto.cmd --ts_proto_out=. ./simple.proto
  • Ensure you're using a modern protoc, i.e. the original protoc 3.0.0 doesn't support the _opt flag

This will generate *.ts source files for the given *.proto types.

If you want to package these source files into an npm package to distribute to clients, just run tsc on them as usual to generate the .js/.d.ts files, and deploy the output as a regular npm package.

Meta

This project is a fork of the excellent ts-proto project, but only outputs some opinionated typescript definition files.
