Andbang-express-auth NPM

And Bang auth middleware for Express.js

World's simplest OAuth.

Sign up for an And Bang account at https://andbang.com
Register your application at https://accounts.andbang.com/developer
When setting your redirect URL, make sure your path is /auth/andbang/callback. For example: localhost:9000/auth/andbang/callback
Copy your app's client ID and secret, and insert them into the middleware's constructor, like in the example below.
Add a link or button that points to /auth somewhere on your page. You can also optionally set the "next" url to go to after successful auth all in one swoop by doing /auth?next={{some URL}}.
...
Profit!

The code below should work once you've dropped in your client ID and secret:

var express = require('express'),
    andbangAuth = require('andbang-express-auth'),
    app = express();

// config our middleware
app.use(express.cookieParser());
app.use(express.session({ secret: 'keyboard cat' }));
app.use(andbangAuth.middleware({
    app: app,
    clientId: '<< YOUR CLIENT ID>>',
    clientSecret: '<< YOUR CLIENT SECRET>>',
    defaultRedirect: '/secured'
}));

// Just re-direct people to '/auth' and the plugin does the rest.
app.get('/', function (req, res) {
    res.send('<a href="/auth">login</a>');
});

// For routes where you want to require login,
// add the middleware like this:
app.get('/secured', andbangAuth.secure(), function (req, res) {
    res.send(req.session.user);
});
