Provide complete bidirectional example if possible?

[alexpdp7]

Can you get working a bidirectional proto using grpcwebproxy and a non-Go server? This seems to be working at https://grpcweb.jbrandhorst.com/ ?

Does #180 need to be merged?

Can you clarify the situation and possible document it? Or list the blockers?

Note: https://grpcweb.jbrandhorst.com/ uses a Go gRPC backend. The source is available at https://github.com/johanbrandhorst/grpcweb-example. For a more minimal example, you can look at https://github.com/johanbrandhorst/grpcweb-boilerplate. I haven't used the standalone proxy but I believe the websocket transport should be supported.

Yeah, I took a look at it, but was a little bit lost, really- I wonder how much GopherJS-specific magic is there or if grpc-web-client can be made to work. The use case for bidirectional streaming on a "regular" gRPC server (even if requiring a proxy) with Typescript on a browser as the client is really important to me.

The GopherJS library just wraps the grpc-web-client, it does all the actual sending of requests. You can definitely do the same thing with just the grpc-web-client. You can take a look at the tests for some examples of how to use bidirectional streaming: https://github.com/improbable-eng/grpc-web/blob/master/test/ts/src/client.websocket.spec.ts#L77

Ah, that's awesome, thanks!

Thinking egotistically, you can close the ticket, although I'd propose leaving it open so this is documented...
