This is an unofficial client library for interacting with Udacity courses and users. It is made up of two parts:

• Catalog
  • A wrapper for Udacity's public Catalog API
• User
  • Log into your Udacity account, see user info, and check course progress

Warning

Note that this is not an official Udacity product. They are allowed to change their internal API at any time, and I will try my best to make sure this library gets updated as well.

In the end, be sure to use this only for personal purposes, not any serious application with a lot of users.

Installation

It's on npm! Just install it from the terminal:

$ npm install udacity-api

You can then include it in your application:

var Catalog = require('udacity-api').Catalog;
var User = require('udacity-api').User;

User

The User object can be used to view a user's account info and see their progress in courses. It includes a lot of convenience functions.

I accept pull requests! Between school, work, and life I can only put in so much time on this project, so all help is appreciated.

Check out TODO.md for some things I've been meaning to get done but haven't.
