[aerogear-dev] AeroGear.js without jQuery Discussion

Tue Apr 1 17:05:23 EDT 2014

I'm all for using promises that actually make sense,
but have you considered consistency?

Are you suggesting some modules will return jQuery.Deferred while others
will use ES6 promises?

I would vote for all or nothing. ;-)

What about allow a developer to override what promise will be returned?
We can pass all promises through singleton (that can be
overwritten/plugged-in by the developer),
and that will decide what promise to return.

In 1.x it can return jQuery.Deferred by default (but can be rewritten to
Promise).
In 2.x it can return Promise (as in ES6) by default (but can be rewritten
to jQuery.Deferred).
