Sketch RelMeAuth strategy for Passport

gistfile1.txt

// mapping relmeauth provider support to local URLs for initiating
// authentication, using OAuth, OAuth 2.0, or just about anything else
passport.use(new RelmeStrategy({
    'twitter.com': '/auth/twitter'
    'facebook.com': '/auth/facebook'
  },
  function(token, profile, done) {
    // relme auth is mostly a discovery mechanism, which redirects
    // the the highest-priority, supported provider.  The verify
    // callback would likely be handled best by the configured
    // FacebookStrategy, TwitterStrategy, etc.  Having a verify
    // callback here is debatable, and likely not needed
  }
));

passport.use(new TwitterStrategy({
    consumerKey: TWITTER_CONSUMER_KEY,
    consumerSecret: TWITTER_CONSUMER_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/twitter/callback"
  },
  associateOAuthUser
));

passport.use(new FacebookStrategy({
    clientID: FACEBOOK_APP_ID,
    clientSecret: FACEBOOK_APP_SECRET,
    callbackURL: "http://localhost:3000/auth/facebook/callback"
  },
  associateOAuth2User
));


// Mount the protocol routes.  This can be trivially wrapped in a single
// function if it seems too boilerplate.
app.get('/auth/facebook', passport.authenticate('facebook'));
app.get('/auth/facebook/callback', passport.authenticate('facebook', { successRedirect: '/',
                                                                       failureRedirect: '/login' }));
