Connect is a slim library for building browser and gRPC-compatible HTTP APIs. You write a short Protocol Buffer schema and implement your application logic, and Connect generates code to handle marshaling, routing, compression, and content type negotiation. 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. Try it with our live demo:

curl \
    --header "Content-Type: application/json" \
    --data '{"sentence": "I feel happy."}' \
