CoffeeScript2: SyntaxError: Cannot use import statement outside a module

I'm working on a express server. I can develop faster using CoffeeScript2 ("write less do more"). The code

import { Sequelize, Model, DataTypes } from 'sequelize'

gives me the error:

SyntaxError: Cannot use import statement outside a module

I guess I have to use babel? How can I set it up?
