Any Ionic Framework users here? How has your experience been so far?

Good for prototyping, bad for large projects !

Ive used it to develop one app so not very experienced. Its quite nice, quick and slick, to work with. Whats not so nice however is startup time for the resulting app(!). I've managed to get it down to something like 4secs but would really liked to see it a little "snappier" than that. Still, its pretty amazing what can be done with a minimum amount of work.

Pretty much what @JohanO said. It's nice, app feels nice to use and development is fast. However startup times can get out of hand, and it can easily devolve into depency hell. Careful with all the cordova/capacitor plugins

Very subjective and dated opinion ahead.

Tried it a few years ago on a hackathon. I instantly hated it, because of angular and the dependency injection crap everywhere.

Would not try it again.

Good for small projects, micro projects.
Bad for everything else, flexibility is zero, cordova and older android, ios versions cause a lot, A LOT of headache. The dependencies break often.
It's nice, until you hit a wall, and that wall is the size of the great wall from GOT. Every F*** time.
