grpc-express

An Express middleware that reverse-proxies HTTP 1.1 REST requests into HTTP 2.0 gRPC requests and back, making gRPC services accessible to browsers without additional client or server modifications. Version 1.0.1-beta is the latest and only release. It is Node.js only, supports unary and server-side streaming calls, and requires an existing gRPC client connection. Alternative solutions like gRPC-web require TypeScript or Go, while grpc-express integrates seamlessly with Express apps.
