I built a product and we bet on Ember back when it, angular and react all looked like top choices. I’d say one of the biggest failures was that it didn’t provide clean upgrades We got stuck with 3.something and no clear path forward. Second, it wanted everything to be Emberized. I forget what exactly it was, but we struggled to wrap other tools in service containers so that they could be injected into our code. I think it was probably Google JS APIs like Maps, which at the time wanted you to load the toolkit their way. Ember-data probably was the biggest mistake to adopt. The amount of time I spent trying to fool some outdated JSON serializer in Rails into embedding something the way ember data wanted was a huge waste. The only other JS I’ve used seriously is Backbone, and once I was waste deep in ember I had major regrets that I didn’t choose it instead.
