Add chat example

[svycka]

Hello @nhooyr,
maybe you could add chat example something like https://github.com/gorilla/websocket/tree/master/examples/chat would be easier to compare both implementations and also would serve as documentation.

https://github.com/gorilla/websocket/tree/master/examples/chat would be easier to compare both implementations and also would serve as documentation.

I feel like the echo example covers the library well while still being light weight. The gorilla chat example is much more involved.

If you feel the echo example along with the comparison in the README does not suffice, then we can explore this.

I think chat example covers a lot more. And yes echo example shows basic usage quite well. But still something like chat example as this a common use case for websocket and easy to understand.

[nhooyr]

Fair enough.

[nhooyr]

My plan is to just remove the echo example and turn it into a full fledged chat example.

[svycka]

@nhooyr not sure why you want to remove it. Why it's bad keeping both? But if you think this way just remove it.

Hi!!

For the past days, I have been working on a chat CLI written in go and using this WebSocket library. I'm not a very experience go developer, but I wanted to learn more and also use WebSockets, which I haven't had the chance to do at my work.

I'm more than happy to go over my example, and if it's good, we can port it as documentation to the library.
Also, I'm happy to work on improving so any issue or PR is welcome.

Here is the repo https://github.com/GustavoCaso/go-chat-websockets

Is missing a README and how to use it, but I plan on keep adding more logic into it. Also, I plan on writing a blog post to help other developers.

Congrats on the library @nhooyr 🎉

I wrote a wrapper using nhooyr/websocket as well - sockparty which is very easy to turn into a chat with a few lines.

That's awesome, please do.

I'll take care of this issue myself though soon as I have similar code already written. I'll add a link to your code and @izzymg's though in the README or wiki.
