Ask HN: What tool do you suggest for Websocket development?

Good question, I'm interested in hearing other people's suggestions.

I don't use go, but I've worked with websockets in Elixir + Phoenix, and one thing that's been really helpful is being able to open up the REPL and broadcast directly to the websocket. Would you be able to do something like this in go?

I dont think so, I haven't seen anything like that

Charlie proxy has great support for viewing web sockets traffic live, which has been a great help for me. Not sure if it can inject traffic though.

You can run a Websocket client in a test suite that tests your server. Have you considered this strategy?

"Currently I'm using Dark Websocket Terminal, and it leaves much to desire for"

What are things you recommend exist in this type of application ?
