Passport-Twitter

Passport strategy for authenticating with Twitter using the OAuth 1.0a API.

This module lets you authenticate using Twitter in your Node.js applications. By plugging into Passport, Twitter authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-twitter

Usage

Configure Strategy

The Twitter authentication strategy authenticates users using a Twitter account and OAuth tokens. The strategy requires a verify callback, which receives the access token and corresponding secret as arguments, as well as profile which contains the authenticated user's Twitter profile. The verify callback must call done providing a user to complete authentication.

In order to identify your application to Twitter, specify the consumer key, consumer secret, and callback URL within options. The consumer key and secret are obtained by creating an application at Twitter's developer site.

passport.use(new TwitterStrategy({
    consumerKey: TWITTER_CONSUMER_KEY,
    consumerSecret: TWITTER_CONSUMER_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/twitter/callback"
  },
  function(token, tokenSecret, profile, done) {
    User.findOrCreate({ twitterId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'twitter' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/auth/twitter',
  passport.authenticate('twitter'));

app.get('/auth/twitter/callback', 
  passport.authenticate('twitter', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('/');
  });
