Updating playing? variable about so-nice HOT 7 CLOSED

Hi @irosenb!

How do you use this @playing variable on the page?

I have tried the same and this variable works when you reload the page. If you want to update the page when the song info updates you need to update this via JavaScript. Check out the lines just below which render the JSON response and check out how the page is updated in JavaScript:

// public/script.js:85
$('#title' ).text(title)

Hey @irosenb, any luck with what you were trying?

@irosenb, did you manage to make it work? Any code that could be added to so-nice?

No I didn't. The problem was that I wanted to pause the music and have the icons change without latency. It seemed almost impossible. When it got pretty smooth, it would mess up if you paused and played very fast. I haven't worked on it in a while so I'm faintly recalling the problem.

Interesting problem: because of the latency and network errors they can get out of sync.
A way to solve this would be to remove the fact that ajax events are asynchronous by queuing all the callbacks somehow, but that isn't trivial.

Another thing that could help would be to reduce the latency by removing one ajax request. Right now the buttons do two Ajax requests: one to PUT the action and another to GET the information. If the PUT returned the new information, it would feel 2x faster!

Another way that comes to mind is to always send and use the current playing state, at every request. So if it does get out of sync it could fall back into place quite quickly.

Closing this for now. Let me know if you're still fiddling with it and we can reopen.
