I started with Ember when the JSON API become the default option for Ember Data.
Now, my biggest show stopper to use Ember in bigger projects is the data layer, because I do my own backends. JSON API is so great from the point of view of Ember, but preparing a nice backend, with relationships and nested objects… can become a nightmare.
I have read some interesting threads about alternatives for the backend, but having one foot in Ember and another foot in a new learned framework seems to me like running on ice.
I am thinking about start again, but using REST.
It seems to me that relationships can be easier in the backend. And also nested objects from PostgreSQL, that I use a lot.
Nobody knows about the future, but Ember is an “opinionated framework”, so it should be great to hear an opinion Im afraid of being outdated somehow in the future Ember developement.
