passport-google-oauth-offline

Google (OAuth) authentication strategies for Passport.

Passport-Google-OAuth

Passport strategies for authenticating with Google using OAuth 1.0a and OAuth 2.0, with offline access to user data.

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.

$ npm install passport-google-oauth-offline

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.

var GoogleStrategy = require('passport-google-oauth').OAuthStrategy;

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);
    });
  }
));

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('/');
  });

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.

var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;

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);
    });
  }
));

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('/');
  });

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