Passport authentication won't pass - node.js

Question

I am trying to use passport authentication with a local strategy but the authentication fails every time and doesn't move on to the local strategy.
I have added a couple console logs to see where the code is derailed but nothing at all is logged.
users.js(router)
var express = require('express');
var router = express.Router();
var User = require('../models/user');
var multer=require('multer');
var passport=require('passport');
var LocalStrategy=require('passport-local').Strategy;
/* GET users listing. */
router.get('/', function(req, res, next) {
res.send('respond with a resource');
});
router.get('/register', function(req, res, next) {
res.render('register',{
'title':'Register'
});
});
router.get('/login', function(req, res, next) {
res.render('login',{
'title':'Login'
});
});
passport.use(new LocalStrategy(
function(username,password,done){
console.log('words');
User.getUserByUsername(username,function(err,user){
if (err) throw err;
if(!user){
console.log('Unknown user');
return done(null,false);
}
});
}
));
router.post('/login',passport.authenticate('local',{failureRedirect:'/users/register'}),function(req,res){
console.log('Authentication succesful');
req.flash('success','You are logged in');
res.redirect('/');
});
module.exports = router;

Answer 1

Did you set the session and added passport to the router? I don't know if setting the initialize and session method in two different spots will work.
This is how I made it work: All set in in a router
let express = require('express');
let session = require('express-session');
let passport = require('passport');
let LocalStrategy = require('passport-local').Strategy;
let router = express.Router();
passport.use(new LocalStrategy(
function(username, password, done) {
User.findOne({username: username}, function (err, user) {
if (err) { return done(err); }
if (!user) {
return done(null, false, { message: 'Incorrect username.' });
}
user.comparePassword(password, function (err, isMatch) {
if (err) { return done(err); }
if(!isMatch){
return done(null, false, { message: 'Incorrect password.' });
} else {
return done(null, user);
}
});
});
}
));
passport.serializeUser(function(user, done) {
done(null, {email: user.email, roles : user.roles});
});
passport.deserializeUser(function(session, done) {
User.findOne({email: session.email}, function(err, user) {
done(err, user);
});
});
router.use(session({ secret: 'my super secret',name: 'my-id', resave: false, saveUninitialized: false }));
router.use(passport.initialize());
router.use(passport.session());
Furthermore if this ever goes into production you need a different session handler than express-session like MongoStore or Redis
The routes
/* GET home page. */
router.get('/', require('connect-ensure-login').ensureLoggedIn('login'), function (req, res, next) {
if (req.user) {
res.render('index');
} else {
res.redirect('/login');
}
});
router.get('/login', function (req, res, next) {
res.render('login');
});
router.post('/login', passport.authenticate('local', {
successRedirect: '/',
failureRedirect: '/login'
}));
router.get('/logout', function (req, res) {
req.logout();
res.render('logout');
});
