Passport-Twitter-Token

Passport strategy for authenticating with Twitter tokens 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.

Installation

$ npm install passport-twitter-token

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 TwitterTokenStrategy({
    consumerKey: TWITTER_CONSUMER_KEY,
    consumerSecret: TWITTER_CONSUMER_SECRET
  },
  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-token' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.post('/auth/twitter/token',
  passport.authenticate('twitter-token'),
  function (req, res) {
    // do something with req.user
    res.send(req.user? 200 : 401);
  }
);

Performing Twitter Reverse Auth Step 1 Server-Side

To remove the need to embed the consumer secret in your client application, you can setup a route to perform step 1 on the server-side.

For example, as route in an Express application using the request module:

var request = require('request');

app.post('/auth/twitter/reverse', function(req, res) {
  var self = this;

  request.post({
      url: 'https://api.twitter.com/oauth/request_token'
    , oauth: { 
          consumer_key: app.set('twitter client key')
        , consumer_secret: app.set('twitter client secret')
      }
    , form: { x_auth_mode: 'reverse_auth' }
  }, function (err, r, body) {
    if (err) {
      return res.send(500, { message: e.message });
    }

    if (body.indexOf('OAuth') !== 0) {
      return res.send(500, { message: 'Malformed response from Twitter' });
    }

    res.send({ x_reverse_auth_parameters: body });
  });
};
