There is a good chance that I'll run into Ember's warts later on but just how easy it was to get started made me so happy. If I do come to the conclusion that it's something to hate, then I hope something comes along to replace it. I've heard great things about Vue.
I couldn't find anything well written and long about Ember from the ten minutes that I googled. Everything mostly seemed to be hot debates in comment sections. I think that as far as full time JavaScript developers, it's a good idea to aim for a React dominant ecosystem. But as a filthy and uncouth back end programmer, I really just want something easy to hook up. I'm not building something super complex and Ember, while it is probably terrible in sections, solves what I need it to do.
Paging data results to increase performance is what I'm working on right now. I want to feed it into a table.
Getting jQuery stuff like datatables working can be annoying and has led me to look at ember addons.
Basically, you're right on the money. I like Ember CLI because it's the closest thing to replicating the ease of Rails development in the Javascript world that I've seen thus far. I'm keeping a keen eye on Angular CLI, but it's not ready for primetime yet.
Most former Ember devs I know have moved onto React. When I mention Ember to them, I often get the response "you're STILL using ember?"
I could spend an hour explaining on all the issues with Ember's execution (it's been blogged about before, many times). I have no problems with "The Framework Approach", but when the happy path tends to always end up in the same bad destination, the community has to stop and think if they're on the right ship.
Source: I'm a full-time EmberJS dev for past 3yrs, dabbler for a couple years before that. If you'd like to discuss exactly what issues I run into daily with Ember, just contact me (my email is on my profile).
