Integrate passport.js from node server file to routes file - node.js

Question

I'm currently trying to utilize passport in my node server for twitter auth on a project. When I have all the code in one server file passport functions as expected. Below is an excerpt from the server file with all the routes in it:
passport.use(new TwitterStrategy({
consumerKey: config.twitter.consumer_key,
consumerSecret: config.twitter.consumer_secret,
callbackURL: config.twitter.callback_url.dev
}, (token, tokenSecret, profile, done) => {
console.log(token, tokenSecret, profile, done);
process.nextTick(() => {
return done(null, profile);
});
}));
app.use(session({ secret: 'SOMESECRET' }));
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(path.join(__dirname, '../public')));
app.set('view engine', 'ejs');
// expose to routes
app.all('*', (request, response, next) => {
request.log = log;
next();
});
app.get('/', (req, res) => {
res.render('pages/index.ejs');
});
// twitter auth endpoint
app.get('/auth/twitter', passport.authenticate('twitter'));
// twitter auth callback endpoint
app.get('/auth/twitter/callback', passport.authenticate('twitter', { failureRedirect: '/' }), (req, res) => {
res.redirect('/');
});
However, when I try to expose passport from the server file to the routes file the authentication never occurs. I've searched most of the questions here and went back to the doc but all the tutorials show one server file with all the routes in it.
Server file:
passport.use(new TwitterStrategy({
consumerKey: config.twitter.consumer_key,
consumerSecret: config.twitter.consumer_secret,
callbackURL: config.twitter.callback_url.dev
}, (token, tokenSecret, profile, done) => {
console.log(token, tokenSecret, profile, done);
process.nextTick(() => {
return done(null, profile);
});
}));
app.use(session({ secret: 'SECRET' })); // session secret
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(path.join(__dirname, '../public')));
app.set('view engine', 'ejs');
// expose to routes
app.all('*', (request, response, next) => {
request.log = log;
request.passport = passport;
next();
});
// routes
app.use('/', routes);
Routes file:
import express from 'express';
const routes = express.Router();
import config from '../config.js';
// main
routes.get('/', (req, res) => {
res.render('pages/index.ejs');
});
// twitter auth endpoint
routes.get('/auth/twitter', (req, res) => {
const passport = req.passport;
passport.authenticate('twitter');
});
// twitter auth callback endpoint
routes.get('/auth/twitter/callback', (req, res) => {
const passport = req.passport;
passport.authenticate('twitter', {
failureRedirect: '/'
});
res.redirect('/');
});
module.exports = routes;
What am I missing here? I'm guessing I cannot use passport.authenticate inside the function for the route. I'm still trying to figure out how to get the version using the routes file working. Any help is appreciated!!

You can require Passport normally no need to get passport by let passport = req.passport. Here is my small demo for Google Oauth by passport
Routes.js
const router = require('express').Router();
const passport = require('passport');
router.get(
'/google',
passport.authenticate('google', {
scope: ['profile', 'email'],
session: false
})
);
router.get(
'/google/callback',
passport.authenticate('google', {
session: false
})
);
Server.js
// passort config
app.use(passport.initialize());
require('./services/passport'); // contains the passport google strategy
// routes
require('./routes')(app);
