+# passport-google-oauth20
+
+[Passport](http://passportjs.org/) strategy for authenticating with [Google](http://www.google.com/)
+using the OAuth 2.0 API.
+
+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](http://www.senchalabs.org/connect/)-style middleware, including
+[Express](http://expressjs.com/).

+
+## Install
+
+```bash
+$ npm install passport-google-oauth20
+```
+
+## Usage
+
+#### Create an Application
+
+Before using `passport-google-oauth20`, you must register an application with
+Google.  If you have not already done so, a new project can be created in the
+[Google Developers Console](https://console.developers.google.com/).
+Your application will be issued a client ID and client secret, which need to be
+provided to the strategy.  You will also need to configure a redirect URI which
+matches the route in your application.
+
+#### Configure Strategy
+
+The Google authentication strategy authenticates users using a Google account
+and OAuth 2.0 tokens.  The client ID and secret obtained when creating an
+application are supplied as options when creating the strategy.  The strategy
+also requires a `verify` callback, which receives the access token and optional
+refresh token, as well as `profile` which contains the authenticated user's
+Google profile.  The `verify` callback must call `cb` providing a user to
+complete authentication.
+
+```javascript
+var GoogleStrategy = require('passport-google-oauth20').Strategy;
+
+passport.use(new GoogleStrategy({
+    clientID: GOOGLE_CLIENT_ID,
+    clientSecret: GOOGLE_CLIENT_SECRET,
+    callbackURL: "http://www.example.com/auth/google/callback"
+  },
+  function(accessToken, refreshToken, profile, cb) {
+    User.findOrCreate({ googleId: profile.id }, function (err, user) {
+      return cb(err, user);
+    });
+  }
+));
+```
+
+#### Authenticate Requests
+
+Use `passport.authenticate()`, specifying the `'google'` strategy, to
+authenticate requests.
+
+For example, as route middleware in an [Express](http://expressjs.com/)
+application:
+
+```javascript
+app.get('/auth/google',
+  passport.authenticate('google', { scope: ['profile'] }));
+
+app.get('/auth/google/callback', 
+  passport.authenticate('google', { failureRedirect: '/login' }),
+  function(req, res) {
+    // Successful authentication, redirect home.
+    res.redirect('/');
+  });
+  ```
+
+## Examples
+
+Developers using the popular [Express](http://expressjs.com/) web framework can
+refer to an [example](https://github.com/passport/express-4.x-facebook-example)
+as a starting point for their own web applications.  The example shows how to
+authenticate users using Facebook.  However, because both Facebook and Google
+use OAuth 2.0, the code is similar.  Simply replace references to Facebook with
+corresponding references to Google.
