Connect Go
Simple, reliable, interoperable. A better gRPC
...It also generates an idiomatic, type-safe client. Handlers and clients support three protocols: gRPC, gRPC-Web, and Connect's own protocol. The Connect protocol is a simple, POST-only protocol that works over HTTP/1.1 or HTTP/2. It takes the best portions of gRPC and gRPC-Web, including streaming, and packages them into a protocol that works equally well in browsers, monoliths, and microservices. Calling a Connect API is as easy as using curl. Handlers and clients also support the gRPC and gRPC-Web protocols, including streaming, headers, trailers, and error details. gRPC-compatible server reflection and health checks are available as standalone packages.
