A protoc plugin to generate Go server and Javascript client Protocol Buffer files to be used for service calls across WebSockets rather than gRPC. (See jnordberg/wsrpc for a pure Javascript solution.)
The first release will generate a TypeScript client to avoid the need for type validations in libraries like dcodeIO/protobuf.js. Which flavor of Javascript client to generate will be implemented as a secondary plugin per the Plugin interface in the protoc-gen-go generator.
