NodeOAuth2

Authentication for Facebook and Google using OAuth2. Authenticates the user and returns their access_token and basic user information.

NOTE: Does not provide a session system to provide a drop-in authentication solution. Most other Facebook node modules do this already; this library simply provides a way to authenticate. Session/account management is up to you to implement.

Dependencies

• underscore
• express
• redis
• connect-redis
• hashlib2

Example

NodeOAuth2 was written with the intention of being used with ExpressJS.

Initialization options

{
	// REQUIRED
	app_id:						Your facebook app secret
	app_secret:					Your facebook app secret
	app: 						Express app instance
	permissions: 				Comma seperated list of facebook permissions
	base_url: 					Base URL of your site/app
	
	// OPTIONAL
	callback_path:  			The path you want facebook to redirect to.
	oauth_complete_redirect:	Callback function OR a path (string) of where to redirect to	
	auth_path: 					Entry point to start OAuth process. Defaults to /auth/facebook
}

Authentication Flow

- User visits /auth/facebook 
- Redirects to Facebook
- User returns from facebook through /oauth/facebook
- Process success or failure
- Redirect to / or execute callback function

Full example

var express 		= require('express'),
	app 			= express(),
	nodeOAuth 		= require('NodeOAuth2'),
	redis_store		= require('connect-redis')(express);

app.configure(function(){
	app.use(express.cookieParser('somesecretkey'));
	app.use(express.session({
			secret: 'secretsessionkey',
			store: new redis_store({
				host: '127.0.0.1',
				port: '6379',
				db: 1,
				prefix: '_auth'
			})
		}
	));
});

var google_data = {
	app_id			:'google-app-id',
