I used ember-materialize and it was quite an enjoyable experience, but it was a really small project so I don’t know how it will hold up in a complex app. It was stalled for a time but is now receiving regular updates.
ember-paper seems to be the most popular and actively maintained, but I didn’t get to use it yet.
I’ve been using semantic UI I and love it. There is an addon (semantic-ui-ember), and there is where most of the usability problems reside
- Not everything is supported
- Most of the time I end up wrapping the behavior in components myself since the addon components either don’t work as expected or there are not flexible enough, since they don’t follow DDAU.
I mean, the addon is great for doing the simple stuff, but more complex behavior in my experience usually meant rolling my own.
They recently started working on a 2.0 version, so hopefully some of the issues are addressed.
Wrapping the library in components can be challenging some times (modal for example)
