[RFE] Support websockets

[amitsaha]

Would you be interested in implementing support for web sockets? I can take a shot.

Not sure about how to test WebSockets. Why don't you take a shot 👍

This is a missing feature kemalcr/kemal#301

Have been just wondering around and I actually have an answer for this, @adamtrilling

1. The server doesn't bind to a port in the TEST environment
2. If you force it to do so, it blocks the entire process, so the test doesn't continue.
   Any ideas how to get around this? I suppose I could run the test and the server in two separate shells, but that won't work in CI.

You could possibly run the server in another Fiber as described here:

# ws_spec.cr

spawn do
  Kemal.run
end

sleep 1 # Give a time for the server to load up

I may not be right, but anyway.

any updates on this? I'm also stuck with this currently :/

specifically how I can simulate multiple clients connecting and talking with each other through my application
