We're a community of busy people learning to code by collaborating on projects for nonprofits. We learn, then use, the JavaScript MEAN stack - MongoDB, Express.js, Angular.js and Node.js.

This app is live at FreeCodeCamp.com, and we have a chat room, blog and forum, too. Join us!

• MongoDB
• Node.js

The easiest way to get started is to clone the repository:

# Get the latest snapshot
git clone --depth=1 https://github.com/freecodecamp/freecodecamp.git freecodecamp

cd freecodecamp

# Install NPM dependencies
npm install

# Create a .env file and populate it with the necessary API keys and secrets:
touch .env

Edit your .env file with the following API keys accordingly (if you only use email login, only the MONGOHQ_URL, SESSION_SECRET, MANDRILL_USER and MANDRILL_PASSWORD fields are necessary:

MONGOHQ_URL='mongodb://localhost:27017/freecodecamp'
SESSION_SECRET='ANY ENGLISH PHRASE'
MANDRILL_USER='THE EMAIL ADDRESS FROM YOUR MANDRILL ACCOUNT'
MANDRILL_PASSWORD='YOUR MANDRILL PASSWORD'
FACEBOOK_ID='FACEBOOK APP API KEY'
FACEBOOK_SECRET='FACEBOOK SECRET'
GITHUB_ID='GITHUB APP API KEY'
GITHUB_SECRET='GITHUB APP SECRET'
TWITTER_KEY='TWITTER APP API KEY'
TWITTER_SECRET='TWITTER APP SECRET'
GOOGLE_ID='GOOGLE APP API KEY'
GOOGLE_SECRET='GOOGLE APP SECRET'
LINKEDIN_ID='LINKEDIN APP API KEY'
LINKEDIN_SECRET='LINKEDIN APP SECRET'

# Seed your database with the challenges
node seed_data/seed_challenges.js                                                                                  

# start the application
gulp

• Improved how unique emails and usernames are handled (with Express-validator)
• Added a tweet button to challenge completion model
• Refactored all views to get rid of any hard-coded challenge information (to make for a better forking experience)
• Installed Helmet to maximize security of application
• Added .env and removed all trace of API keys from git history

We welcome pull requests from Free Code Camp "Code Campers" (our students) and seasoned JavaScript developers alike!

1. Check our public Trello Board
2. If your issue or feature isn't on the board, either open an issue on this GitHub repo or message Quincy Larson to request to be added to the Trello board.
3. Once your code is ready, submit the pull request. We'll do a quick code review and give you feedback, and iterate from there.

This project uses Airbnb JavaScript Style Guide with a few minor exceptions. If you are submitting a pull request that involves Jade templates, please make sure you are using spaces, not tabs.
