Passport.js Tokenerror After Deployment To Production

I have a MERN stack app which uses Passport.js for Facebook/Twitter/Google authentication. In the development environment, everything works well and we are able to authenticate the

Solution 1:

use passport-twitter-token instead of passport-twitter library that contains a strategy for Twitter authentication, but this library is not suitable for RESTful API. It is better suited for Express.js applications which are used with some server rendering The code for initialization of Passport with Twitter strategy looks like this:

'use strict';

var passport = require('passport'),
  TwitterTokenStrategy = require('passport-twitter-token'),
  User = require('mongoose').model('User');

module.exports = function () {

  passport.use(newTwitterTokenStrategy({
      consumerKey: 'KEY',
      consumerSecret: 'SECRET',
      includeEmail: true
    },
    function (token, tokenSecret, profile, done) {
      User.upsertTwitterUser(token, tokenSecret, profile, 
function(err, user) {
        returndone(err, user);
      });
    }));

};
