protobufjs-loader

Webpack loader for translating .proto definitions into protobuf.js modules, equivalent to running the pbjs CLI at build time. Current stable version is 3.1.1, released January 2025 with async/await refactor and custom TypeScript output locations. Requires webpack ^5.0.0 (breaking change from v2 to v3 dropped webpack 4 support). Supports both static-module and json-module targets, and optional pbts TypeScript declaration generation. Alternatives: grpc-tools or manual pbjs invocation. Release cadence irregular, maintained by kmontag.
