[aerogear-dev] UnifiedPush Node sender move to Promises

Hello people, I think i would like to move the unifiedpush-node-sender, https://github.com/aerogear/aerogear-unifiedpush-nodejs-client , to be Promise based. Currently it uses callback pattern that many node.js packages use as well as emitting events. When i first created this 3 years ago, that was sort of the standard way of doing things, but Promises have become very popular(i know i love them :)) and have been a native feature since node 0.12.x considering we have not yet hit a 1.0.0, we can pretty much just make this change and we will be ok. If this is to big of a change all at once, we could always do both callbacks and Promises. I think we did this for Datamanager in the past. Perhaps once we fully move to promises, then we can hit a 1.0.0 My only concern is other projects that might be using the sender that are not yet on node 0.12 or above, since this is when promises became native. I would really like to not have to include the polyfill. i suppose those users would need to stick to the previous versions then. anyway, would like to hear some thoughts. -Luke
