Create a websockets library #8994

Open buddha314 opened 6 years ago

I know this will probably get picked up by the community, but I thought I'd throw it out there.

Perusing the Wikipedia Comparision of WebSockets page I came across libwebsockets which might be a nice base line.

The most compelling use case (for me) is moving real time simulation visualization into HTML5 applications using technology like D3 or whatever the new hotness is.

@buddha314 , I can work on a version for libwebsocket. My issue is that I could not integrate libwebsocket socket handler with the Chrest. Now I can create an exclusive websocket class with libwebsocket, but the port cannot be the same port where Chrest http is running. I recognize that this is not the ideal solution, but it is what I am figuring out. The problem is: 1)Chrest has an async event loop. 2) libwebsocket has it own async event loop. I do not know how to share the socket descriptor with both loops.

But if you do not mind to connect with WebSocket service with a different port than the Chrest http rest server. I can create special Class that to handles websocket connections.

I don't honestly know the best architecture. In looking around, it looks like Flask uses separate packages to handle websockets: https://stackoverflow.com/questions/32935877/best-option-currently-available-for-websockets-with-flask-on-python3#32936484 So that might be the correct direction.. I think ...?

I am exploring libwebsocket. As soon as possible I will inform my experiments results.
