`grpcweb` implements the gRPC-Web spec as a wrapper around a gRPC-Go Server.
|
|
|
|
It allows web clients (see companion JS library) to talk to gRPC-Go servers over the gRPC-Web spec. It supports
|
|
HTTP/1.1 and HTTP2 encoding of a gRPC stream and supports unary and server-side streaming RPCs. Bi-di and client
|
|
streams are unsupported due to limitations in browser protocol support.
|
|
|
|
See https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-WEB.md for the protocol specification.
|
|
|
|
Here's an example of how to use it inside an existing gRPC Go server on a separate http.Server that serves over TLS:
|
|
|
|
grpcServer := grpc.Server()
|
|
wrappedGrpc := grpcweb.WrapServer(grpcServer)
|
|
tlsHttpServer.Handler = http.HandlerFunc(func(resp http.ResponseWriter, req *http.Request) {
|
|
if wrappedGrpc.IsGrpcWebRequest(req) {
|
|
wrappedGrpc.ServeHTTP(resp, req)
|
|
}
|
|
// Fall back to other servers.
|
|
http.DefaultServeMux.ServeHTTP(resp, req)
|
|
})
|
|
|
|
If you'd like to have a standalone binary, please take a look at `grpcwebproxy`.
