A pure TypeScript Protocol Buffers implementation with a protoc code-generation plugin and RPC client/server support. It generates typed message classes with binary/JSON serialization, reflection, and clients for gRPC, gRPC-Web, and Twirp.

Use cases

• serialize protobuf messages in TypeScript
• generate TypeScript code from .proto files
• call gRPC services from a browser
• build a Twirp or gRPC server in Node.js with TypeScript
• handle 64-bit integers with bigint in protobuf
• use proto3 JSON format with strict conformance

When to choose

• You want type-safe protobuf serialization in pure TypeScript
• You need gRPC, gRPC-Web, or Twirp clients/servers in Node.js or the browser
• You need strict protobuf conformance, reflection, or well-known types support

When to avoid

• You use JavaScript without TypeScript and don't want generated typed code
• You need protobuf support for languages other than TypeScript
• You need a runtime-only schema-less protobuf decoder without code generation
