Building OAuth Strategies with passport.js Chapter 7

Adding necessary routes for LinkedIn login

Now, let's add the necessary routes for when we click on the Login button and when we

receive the callback from LinkedIn:

const User = require('../models/User.js');

const passport = require('passport');

const config = require('./../config/Config');

const Strategy = require('passport-linkedin').Strategy;

module.exports.controller = (app) => {

// linkedin strategy

passport.use(new Strategy({

consumerKey: config.LINKEDIN_APP_ID,

consumerSecret: config.LINKEDIN_APP_SECRET,

callbackURL: '/login/linkedin/return',

profileFields: ['id', 'first-name', 'last-name', 'email-address']

},

(accessToken, refreshToken, profile, cb) => {

// Handle linkedin login

}));

app.get('/login/linkedin',

passport.authenticate('linkedin'));

app.get('/login/linkedin/return',

passport.authenticate('linkedin', { failureRedirect: '/login' }),

(req, res) => {

res.redirect('/');

});

};

In the preceding code, we have added two routes. If you remember, in Login.vue, we

have added a link to http://localhost:8081/login/linkedin, which will be served

by the first route that we defined here.

Also, if you recall, in the configuration setting, we have added a callback function that will

be served by the second route, which we have defined here as well.

Now, the final thing to do is to actually log in the user using the strategy. Replace the
contents of linkedin.js with the following:

const User = require('../models/User');

const passport = require('passport');

const config = require('./../config/Config');

const Strategy = require('passport-linkedin').Strategy;
