chat.io

A Real-Time Chat Application built using Node.js, Express, Mongoose, Socket.io, Passport, & Redis. The configurations on production will be assigned from Environment Variables on Heroku, while the development configurations reside inside app/config/config.json file. You need to create a database on MongoLab, then create a database user, get the MongoDB URI, and assign it to dbURI. You need to register a new application on both Facebook and Twitter to get your tokens by which users can grant access to your application, and log in using their social accounts. The session needs a random string to make sure the session id in the browser is random. That random string is used to encrypt the session id in the browser, Why? To prevent session id guessing. Each user has a username, password, social Id, and picture. If the user is logged in via username and password, then the social Id has to be null, and the if logged in via a social account, then the password will be null.
