Ask HN: Suggestions for an opinionated Node.js framework with ES2016 syntax?

I am about to start a new project and have been evaluating the various NodeJS frameworks out there. As everyone knows, its sort of "choose your own adventure" right now and the sheer scope of choices are insane. My hope is to find something with the following attributes:

- Well suited to creating a RESTful API - Node V4.x and above support - ES2015 syntax support (no Babel transpiling) - Stable, good documentation and community (this is a big one) - Opinionated. For example, we’ve been using SailsJS and its great except doesn't support ES2015 and can be a little slow - ORM support. Preferably with a MongoDB connection option. - client side support is unnecessary

So far the most promising one I've found is AdonisJS. Any other suggestions would be appreciated
