passport-twitch

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

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

Install

$ npm install passport-twitch

Usage

Configure Strategy

The Twitch OAuth 2.0 authentication strategy authenticates users using a Twitch account and OAuth 2.0 tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifiying a client ID, client secret, and callback URL.

passport.use(new TwitchStrategy({
    clientID: TWITCH_CLIENT_ID,
    clientSecret: TWITCH_CLIENT_SECRET,
    callbackURL: 'http://localhost:3000/auth/twitch/callback',
    scope: 'user:read:email analytics:read:games'
  },
  function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({ twitchId: profile.id }, function (err, user) {
      return cb(err, user);
    });
  }
));

Authentication Requests

Use passport.authenticate(), and specify the twitch strategy to authenticate requests.

For example, as a route middleware in an Express application:

app.get('/auth/twitch', passport.authenticate('twitch'));
app.get('/auth/twitch/callback', passport.authenticate('twitch', { failiureRedirect: '/login' }), function(req, res) {
  res.redirect('/');
});

Optionally, the forceVerify option can be set to true to indicate that the user should be re-prompted for authorization:

app.get('/auth/twitch', passport.authenticate('twitch', { forceVerify : true }));
