The current release is a Pre-Alpha release, mainly for early adopters to provide feedback on the JS API (both gRPC and Protobuf). The JS client library has been used by Google (Alphabet) projects with Closure compiler and its TypeScript generator (not yet open-sourced). The use of Closure compiler may or may not fit your JS development environment.
The gateway that connects the client to the server uses Nginx. However, Nginx still doesn't support HTTP/2 (to backends) as of Q2/2017, and therefore the gateway can't be used as a reverse proxy (for load balancing). We have also added the gRPC-Web support to Envoy. In future, we expect gRPC-Web to be supported in language-specific Web frameworks, such as Go, Java, Node, which will eliminate the need to deploy a gateway.
We expect to ship an alpha version in Q3/2017. Stay tuned! Sign-up form.
