A protoc plugin that generates TypeScript declaration files (.d.ts) matching the JavaScript output of protoc's CommonJS mode. It can also emit gRPC service client definitions for grpc-web and grpc-node.

Use cases

• generate TypeScript types for protobuf messages
• add type hints to protoc-generated CommonJS JavaScript modules
• generate gRPC-Web client stubs in TypeScript
• generate service definitions for grpc-node
• integrate protocol buffers into a TypeScript build pipeline

When to choose

• you use protoc's js_out with CommonJS import style and want typed messages
• you build a browser client with grpc-web and need TypeScript service definitions
• you want typed protobuf message declarations without hand-writing .d.ts files

When to avoid

• you use protobuf-es, ts-proto, or protobuf.js instead of protoc's js_out output
• you need runtime serialization libraries rather than type declarations
• you use Closure-style or ES module protoc output instead of CommonJS
