Passport-Twitch.tv

Passport strategy for authenticating with Twtich.tv using the OAuth 2.0 API.

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

Install

$ npm install passport-twitchtv

Usage

Configure Strategy

The Twitch.tv authentication strategy authenticates users using a Twitch.tv account and OAuth tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifying a consumer key, consumer secret, and callback URL.

A scope is required, all scopes are available here

passport.use(new TwitchtvStrategy({
    clientID: TWITCHTV_CLIENT_ID,
    clientSecret: TWITCHTV_CLIENT_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/twitchtv/callback",
    scope: "user_read"
  },
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ twitchtvId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

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

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

Examples

For a complete, working example, refer to the login example.
