ember-infinity demo as Ember Twiddle for presenting issues

[openhouse]

ember-infinity forever!

Here is the ember-infinity demo as an Ember Twiddle. People could fork this to mock up their issues. This could be something for the docs? https://ember-twiddle.com/c08988c41ef999bc0ef34bb0d92c17e5

Ember Twiddle is a great JS Bin sort of thing which lets you use addons in an ember-cli style layout.

I made this on my way to mocking up an issue I'm having (HeroicEric/ember-group-by#12). I want to group items from an infinityModel. But it seems that using ember-group-by causes the DOM for whole list to redraw whenever ember-infinity adds new items to the model. This slows with each page. Any tips on how to group infinityModel items would be appreciated!

yo @openhouse ! this is a little tricky. In a situation like this, I'd try keeping the infinityModel array privately, and then creating the groups based on the data in the infinityModel, via the afterInfinityModel hook.

Check it out:

Not sure this approach would work out of the box with ember-group-by, but looking at the logic there, it shouldnt be all that hard to replicate & modify for a data source that's getting larger & larger over time.

Please re-open if this doesn't quite solve your problem!

@hhff I will try this, thanks!
