passport-token-facebook v1.0.6

passport-token-facebook

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

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

Install

$ npm install passport-token-facebook

Usage

Configure Strategy

The Facebook authentication strategy authenticates users using a Facebook 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 specifying an app ID, app secret, and optionally enabling appsecret_proof.

passport.use(new TokenFacebookStrategy({
    clientID: FACEBOOK_APP_ID,
    clientSecret: FACEBOOK_APP_SECRET,
    enableProof: false
  },
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ facebookId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'token-facebook' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/auth/token-facebook',
  passport.authenticate('token-facebook'),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('/');
  });

Profile Fields

The Facebook profile is very rich, and may contain a lot of information. The strategy can be configured with a profileFields parameter which specifies a list of fields (named by Portable Contacts convention) your application needs. For example, to fetch only user's facebook ID, name, and picture, configure strategy like this.

passport.use(new TokenFacebookStrategy({
    // clientID and clientSecret
    profileFields: ['id', 'displayName', 'photos']
  },
  // verify callback
));

If profileFields is not specified, the default fields supplied by Facebook will be parsed.
