Well I guess I figured out username is required - not super obvious.
And then chat messages that I sent usually don’t show up until I refresh the page.
Also things are just very slow (not sure if that’s Hologram itself right now, or something else).
Overall I would spend some more time polishing this up if it’s intended to show off Hologram.
Same here. looks like the SSE part is not working. I am not on mobile; desktop Firefox.
It is quite snappy for me; but then I have a <20ms ping time to the server.
Cool stuff, congrats!
If you open the browser console there are a few errors (a FunctionClauseError among them) that I suspect are behind the funky behaviour, so that’s probably where I’d start. (Happy to help if you get stuck)
One separate note: the broadcasting goes through Hologram.Realtime.* directly, which is meant more as an escape hatch. For chat it’s better to use put_broadcast from inside a handler - it’s transactional, so the send is tied to the handler succeeding. It’s usually a small change too: if whatever does the broadcast is reachable from a handler that carries the server struct (like init/3 or command/3), you just thread that server struct down to it and call put_broadcast there.
fwiw, I see the same occasionally. Sometimes they appear just fine, albeit a bit delayed (not sure where the app is hosted it but I’m in Texas). Not sure what the underlying issue is. The only error I see in the console is:
[Error] Failed to save page snapshot to OPFS:
TypeError: (await(await navigator.storage.getDirectory()).getFileHandle(i,{create:!0})).createWritable is not a function. (In '(await(await navigator.storage.getDirectory()).getFileHandle(i,{create:!0})).createWritable()', '(await(await navigator.storage.getDirectory()).getFileHandle(i,{create:!0})).createWritable' is undefined)

But I don’t think that is related necessarily.
Cool stuff!
Here are some bugs I found:
