Passport-Google-OAuth

Passport strategies for authenticating with Google using OAuth 1.0a and OAuth 2.0.

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

Install

$ npm install passport-google-oauth

Usage of OAuth 1.0

Configure Strategy

The Google OAuth 1.0 authentication strategy authenticates users using a Google 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.

passport.use(new GoogleStrategy({
    consumerKey: GOOGLE_CONSUMER_KEY,
    consumerSecret: GOOGLE_CONSUMER_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/google/callback"
  },
  function(token, tokenSecret, profile, done) {
    User.findOrCreate({ googleId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/google',
  passport.authenticate('google', { scope: 'https://www.google.com/m8/feeds' }));

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

Usage of OAuth 2.0

Configure Strategy

The Google OAuth 2.0 authentication strategy authenticates users using a Google 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 a client ID, client secret, and callback URL.

passport.use(new GoogleStrategy({
    clientID: GOOGLE_CLIENT_ID,
    clientSecret: GOOGLE_CLIENT_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/google/callback"
  },
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ googleId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

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

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

Examples

For a complete, working example, refer to the OAuth 1.0 example and the OAuth 2.0 example.
