node-red-contrib-grpc

A gRPC wrapper for Node-RED providing both server and client nodes (grpc-server, grpc-register-function, grpc-response, grpc-call). Version 1.2.5 is the latest stable release as of 2024, with moderate release cadence. It allows building gRPC services within Node-RED flows, supporting protocol buffer definitions and bidirectional streaming. Key differentiator: no custom coding required for gRPC integration within Node-RED, unlike using raw grpc-js packages.
