passport-oauth2

General-purpose OAuth 2.0 authentication strategy for Passport.

This module lets you authenticate using OAuth 2.0 in your Node.js applications. By plugging into Passport, OAuth 2.0-based sign in can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Note that this strategy provides generic OAuth 2.0 support. In many cases, a provider-specific strategy can be used instead, which cuts down on unnecessary configuration, and accommodates any provider-specific quirks. See the list for supported providers.

Developers who need to implement authentication against an OAuth 2.0 provider that is not already supported are encouraged to sub-class this strategy. If you choose to open source the new provider-specific strategy, please add it to the list so other people can find it.

Usage

Configure Strategy

The OAuth 2.0 authentication strategy authenticates users using a third-party account and OAuth 2.0 tokens. The provider's OAuth 2.0 endpoints, as well as the client identifer and secret, are specified as options. The strategy requires a verify callback, which receives an access token and profile, and calls cb providing a user.

passport.use(new OAuth2Strategy({
    authorizationURL: 'https://www.example.com/oauth2/authorize',
    tokenURL: 'https://www.example.com/oauth2/token',
    clientID: EXAMPLE_CLIENT_ID,
    clientSecret: EXAMPLE_CLIENT_SECRET,
    callbackURL: "http://localhost:3000/auth/example/callback"
  },
  function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({ exampleId: profile.id }, function (err, user) {
      return cb(err, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'oauth2' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/auth/example',
  passport.authenticate('oauth2'));

app.get('/auth/example/callback',
  passport.authenticate('oauth2', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('/');
  });
