Example suggestion

[noprompt]

It would be great if there were a minimal working example using chord with http-kit. The current example uses a lot of tools from several libraries, which is fine, but makes it difficult to understand at a basic level how to use this library. I'd be happy to send you a pull request of such an example but I'm having difficulty hooking it up. :wink:

Would also be great if the example included an example of broadcasting through websocket to all clients

Hi Simen - I'm pretty sure I've got an example of that kicking around somewhere - will see what I can find.

I've managed to do the broadcasting by having the server hold a reference to a mult and tapping with a dropping buffer for each new web socket channel. I'm unsure how to avoid leaking channels. I have regular updates sent from the server, so how do I clean up when a client leaves? The dropping buffer was a workaround to avoid holding up the mult.

Any luck finding that example @james-henderson ? I'm running into trouble using mults to distribute to clients. When I hit refresh in a client's browser, it seems to hang on to the tap (never untapped) and therefore holds the mult up indefinitely. There must be a better way I'm missing! Dropping-buffer just seems to lose important events.

I couldn't find it, I'm afraid - I've moved companies since so it is probably in an old proprietary codebase :( Will take a look at your code snippets when I get a moment :)

Alright no worries. You may find I switched to another popular library ;)

Strewth that was quick. Sorry.

@dxlr8r @camelpunch I've updated the example app to be a 'multiplayer chat' app - have a look here for the handler code.

Let me know what you think :)

[camelpunch]

Looks good. What's the thing I'm likely to be missing if, say, dead clients cause future ones to be unresponsive? As an aside, switching to Sente removed the problem, but then Sente does all sorts of reconnecting magic and wraps all sends in a function.

[jarohen]

As a guess, I'd say probably the call to untap - if you don't untap from a mult, then every time you send a message to the mult, it waits for all tapped channels to take the message before accepting the next message.
