Using Nodemailer in an Ember.js app

I am currently building a website with ember-cli. It’s fun and I make progress and learn this framework.

Now I want to use Nodemailer for sending an contact form. I figured it out how to send a mail with nodemailer from my terminal, but I don’t have a clue how it should work in combination with Ember. I simply don’t know how to connect the front-end to the back-end. And do I need to set up a server?

I haven’t build any Node.js apps yet, so please be so kind and give me a hint where I can find some advice without making an nodeschool.io course.

Thank you in advance!
