Usage of OAuth2-Meetup

Configure Strategy

This authentication strategy authenticates users using their meetup account. Users have to be logged on to Meetup.com to complete the process. Meetup API does not supply username or email for its user profile. This strategy has been tweaked to include auto generation of username. The username will be identified as meetup_<meetupID>. The auto generation can be disabled. If there is no username generated, there will be nothing to identify the user unless the user has already logged on. Passport.connect function has to be modified to continue the process even when there are no username or email provided.

// If neither an email or a username was available in the profile, we don't
// have a way of identifying the user in the future. Throw an error and let
// whoever's next in the line take care of it.
if (!user.username && !user.email) {
  if(!req.user || provider != 'meetup') return next(new Error('Neither a username nor email was available'));
}

If username is auto generated, the process should carry on smoothly.

var MeetupOAuth2Strategy = require('passport-oauth2-meetup').Strategy;

passport.use(new MeetupOAuth2Strategy({
  clientID: MEETUP_KEY,
  clientSecret: MEETUP_SECRET,
  callbackURL: "http://127.0.0.1:3000/auth/meetup/callback",
  autoGenerateUsername: true
}, function(accessToken, refreshToken, profile, done) {
    return done(null, profile);
}));

Authenticate Requests

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

app.get('/auth/meetup',
  passport.authenticate('meetup', { session: false }),
  function(req, res) {
    res.json(req.user);
  });
