TwirpScript

TwirpScript is a Protocol Buffers (Protobuf) RPC framework designed for JavaScript and TypeScript environments. It automates the generation of both client and server code from `.proto` service definitions, facilitating type-safe communication in both browser and Node.js runtimes. The package is currently at version 0.0.72 and maintains an active release cadence with frequent minor updates addressing bug fixes and improvements. A key differentiator is its adherence to the Twirp Wire Protocol (v7) and its focus on minimizing bundle sizes, especially through tree-shaking and a lightweight runtime (2KB for TwirpScript, 37KB for the underlying ProtoScript serialization runtime). This makes it an efficient alternative to larger RPC frameworks, particularly for web applications requiring lean client bundles and strict type enforcement.
