app.import() works with
node_modules now! As of Ember 2.15. Previously it only worked with
app.import are here:
This method (vendor-shim) wraps the global export into an es6 module (but the global one is still present). It doesn't use an es6 interface even if the library offers one, but that's okay for my use case.
Things could still be easier, see this thread for the current state of that.
