Wish List - Get rid of promises

[sethbrasile]

I would love it if it was possible to open/close modals in quick succession without using promises. I believe this may be possible with ember-concurrency, but I don't want to add another dependency to the consuming app since this is, in fact, just a modal addon. Please leave a suggestion if you have one!

I'm curious how ember-concurrency could help? Promises or co-routines the two would have the same issue. Aside from cancellation support which you could implement a simple case here if you assume you only want one modal open at a time. I'd like to hear more thoughts on how you feel e-c would help. And then discuss how you could accomplish the same thing with some fancy promise-chain footwork to avoid adding a dependency.

@sukima this was a very long time ago (sorry, been away from developer-land for a few years...) so I could be misremembering:

From what I recall, I was wanting to internally track state so that the user didn't need to worry about it. I wonder if there was a reason I didn't think promises were the right route? I don't see why we couldn't internally track state with promises..

You know, I think I tried and maybe ran into issues stacking promises. I think I could get an open-close succession to work, but not open-close-open, so I ended up just returning the promise and letting the user handle it.

I'm sorry that I don't remember! If I get a chance, I can dive back into this, but I'm not sure.

@sethbrasile You might be right. I cannot remember either. However I did do a lot of study into the remodal and ember-remodal code and developed a wrapper for it that I think handles the open-close-open for you. My ember add on ember-confirmed has a ember-remodal-redux component that moves the management of modals to the user via a manager API. Here is an example of such a use case: https://ember-twiddle.com/64bc114b4ba5b3ff6a2fb770d1946fed

The basic idea is that the ember-remodal-redux component handles the open and close promises for you the API you see as a developer is simply a Confirmer object. The addon offers a Manager object to open and close the modal programmatically.
