I've a side project (web application) I’ve done a few years back for a family member (Java 6, JBoss 4, using an obscure java web framework based on JSF + ExtJS... it was really productive at the time, but the framework is mostly unmaintained and so is my app). It’s mostly CRUD, but lots of it.

I’m thinking of throwing it all away and starting from scratch as I feel the task to bring it “up do date” is just to much work. I do have the legacy data to deal with, that’s what been holding me back (it’s very coupled with the framework).

The stack I’m most comfortable with is Java 8, Play Framework (for REST API) and EmberJS for the front-end, so I’m tempted to go with that as I would like to be as productive as possible, but I was wondering if there was something out there that I should consider (even if making me slower in the beginning).

Ideally something with lot’s of community addons/plugins and open-source and probably conventions. I’m very fond of EmberJS because of the amount of decisions that I don’t have to make and all of the things I don't have to implement/glue myself.

Thanks for any input.
