Questions tagged [grpc-web]

gRPC-Web provides a JavaScript library that lets browser clients access a gRPC service.

gRPC is an open source remote procedure call (RPC) system initially developed at Google. It uses HTTP/2 for transport, Protocol Buffers as the interface description language, and provides features such as authentication, bidirectional streaming and flow control, blocking or nonblocking bindings, and cancellation and timeouts.
