usable

Hey

i am a golang programmer, but for the last 2 months been working on flutter and angular 2 in dart.

i am seriously needing a way for Dart to interoperate with golang.
GRPC really seems like the way forward i feel.

But this is the only library i have found.
Is this stable / usable yet ?

Hi Joe,

as I described in the readme file, this is a proof-of-concept. One thing missing is grpc compression. The http2 implementation it uses is missing stream prioritization.

That being said, one goal of the grpc team was that it should be very easy adapt to new languages (given an http2 implementation). So it might not take much more code than this proof of concept.

sounds like i can try it out.

I doubt it wil work in a browser, because of the lack of header / framing support in the browsers.
Normally you put a gateway in front. See grpc gateway - https://github.com/grpc-ecosystem/grpc-gateway.
Did you try using it in a browser ?

But it looks like it will work server to server

[mkustermann]

I agree, it won't work inside a browser due to the lack of normal socket support. It's the first time I hear of grpc-gateway, so I don't know how it works. But I doubt that it will be fully compatible with normal grpc due to the lack of streaming.

thanks for the answer.

I am thinking now of a better way to get dart to talk to golang that is low friction.
stdio is pretty horrible.

Here are my scenarios:
This scenarios i know how to do:
I have a Dart client (web thing wrapped in electron).
I have a golang server, that is just publishing web sockets and restful json

This scenario i dont knwo how to do:
I have a Dart client (web thing wrapped in electron).
I have a dart server, that is publishing web sockets and restful json. I woudl prefer a nice RPC JSON though :)
I have a golang application server, that is called by the dart server. No idea how to allow them to do RPC.

If you have any ideas please let me know. I will close this issue if i am bugging you too much of course...

here is the link for you:

The gateway is in there

websocket support:

@mkustermann There is now an agreed spec for GRPC-web

So a Dart implementation is now doable that will work on FLutter and Dart web.

grpc/grpc#8682
See the top link for the link to the Spec.

I would like to help on Te Dart code.
