passport-twitter-oauth2

Passport strategy for authenticating with Twitter using the OAuth 2.0 API.

This Strategy was modifed directly from Jared Hanson's passport-facebook OAuth 2.0 Strategy and passport-twitter OAuth 1.0a Strategy modules. This project was taken and modified and released to support Twitter OAuth 2.0 pipelines

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-oauth2

Usage

Create an Application

Before using passport-twitter-oauth2, you must register an application with Twitter. If you have not already done so, a new application can be created at Twitter Apps. Your application will be issued an app ID and app secret, which need to be provided to the strategy. You will also need to configure a redirect URI which matches the route in your application.

Configure Strategy

The Twitter authentication strategy authenticates users using a Twitter account and OAuth 2.0 tokens. The app ID and secret obtained when creating an application are supplied as options when creating the strategy. The strategy also requires a verify callback, which receives the access token and optional refresh token, as well as profile which contains the authenticated user's Twitter profile. The verify callback must call cb providing a user to complete authentication.

passport.use(new FacebookStrategy({ clientID: TWITTER_APP_ID, clientSecret: TWITTER_APP_SECRET, callbackURL: "http://localhost:3000/auth/twitter/callback" }, function(accessToken, refreshToken, profile, cb) { User.findOrCreate({ twitterId: profile.id }, function (err, user) { return cb(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('/'); });

Examples

Developers using the popular Express web framework can refer to an example as a starting point for their own web applications.

FAQ

How do I ask a user for additional permissions?

If you need additional permissions from the user, the permissions can be requested via the scope option to passport.authenticate().

app.get('/auth/twitter', passport.authenticate('twitter', { scope: ['user_friends', 'manage_pages'] }));

Refer to permissions with Twitter Login for further details.

How do I re-ask for for declined permissions?

Set the authType option to rerequest when authenticating.

app.get('/auth/twitter', passport.authenticate('twitter', { authType: 'rerequest', scope: ['user_friends', 'manage_pages'] }));
How do I obtain a user profile with specific fields?

The Twitter profile contains a lot of information about a user. By default, not all the fields in a profile are returned. The fields needed by an application can be indicated by setting the profileFields option.

new TwitterStrategy({ clientID: TWITTER_APP_ID, clientSecret: TWITTER_APP_SECRET, callbackURL: "http://localhost:3000/auth/twitter/callback", profileFields: ['id', 'displayName', 'photos', 'email'] }), ...)
How do I obtain a user's email address?

Set the includeEmail option when creating the strategy.

new TwitterStrategy({ clientID: TWITTER_APP_ID, clientSecret: TWITTER_APP_SECRET, callbackURL: "http://localhost:3000/auth/twitter/callback", includeEmail: true }, ...)
