For becoming a Front-End Developer you'll have to learn:
- HTML5
- CSS3 and the preprocessors
- JavaScript
From JavaScript you have to learn also it's frameworks and libraries like:
Angular, Ember, Meteor, React, Vue... (I wrote them in alphabetical order).
Meteor.js is both front and back end.

And they work perfect with MongoDB.
