  },
  auth: {

    tokenPath: '/oauth/access_token'
  }
});

router.get('/auth/facebook', (req, res) => {
  const authorizationUri = oauth2.authorizationCode.authorizeURL({
    redirect_uri: 'http://localhost:3000/auth/facebook/callback',
    scope: ['email']
  });

  res.redirect(authorizationUri);
});

router.get('/auth/facebook/callback', async(req, res) => {
  const code = req.query.code;
  const options = {
    code,
    redirect_uri: 'http://localhost:3000/auth/facebook/callback'
  };

  try {
    // The resulting token.
    const result = await oauth2.authorizationCode.getToken(options);

    // Exchange for the access token.
    const token = oauth2.accessToken.create(result);

    return res.status(200).json(token);
  } catch (error) {
    console.error('Access Token Error', error.message);
    return res.status(500).json('Authentication failed');

// Ask the user to authorize.
router.get('/auth/facebook', facebook.authorize);
