throw new TypeError('app.use() requires middleware functions');

I am following an online course on Nodejs and was trying to implement basic authentication in my express application. But I am getting error on app.use(new localStrategy(User.Authenticate()); I have tried reinstalling the 'passport-local'. Why this error keeps persisting ?

var express = require('express'), 
app = express(), 
mongoose = require('mongoose'),
passport = require('passport'),
User = require('./models/user'),
bodyParser = require('body-parser'),
localStrategy = require('passport-local');   ;
passportLocalMongoose = require('passport-local-mongoose');
mongoose.connect('mongodb://localhost/auth_DB');

app.use(bodyParser.urlencoded({extended: true}));
app.use(express.static('images'));

app.use(require('express-session')({
    secret: 'pppppqpqsda dasdqw ksndfkjnzmmuawt8ikweabmdsfj a',
    resave: false,
    saveUninitialized: false 
}));

app.use(passport.initialize());
app.use(passport.session());
app.use(new localStrategy(User.authenticate()));

passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

app.set('view engine', 'ejs');

app.get('/', function (req, res) {
    // body...
    res.render('home');
});

app.get('/secret', function (req, res) {
    // body...
    res.render('secret');
});



app.get('/register', function (req, res) {
    // body...
    res.render('signup');
});

app.post('/register', function (req, res) {

    User.register(new User({username: req.body.username}), req.body.password, function(err, user){
        if(err){
            console.log(err);
            return res.render('signup');
        }

    passport.authenticate('local')(req, res, function(){
        res.redirect('/secret');
    });

});

});


app.get('/login', function (req, res) {
    // body...
    res.render('signin');
});

app.post('/login', passport.authenticate('local', 
              {successRedirect: '/secret', 
               failureRedirect: '/login'} ),
    function(req, res){});


app.listen(3000, function(){
    console.log('Server Started!');
});

User.js:-

var mongoose = require('mongoose');
var passportLocalMongoose = require('passport-local-mongoose');
var userSchema = new mongoose.Schema({
    username: String,
    password: String
});

userSchema.plugin(passportLocalMongoose);
module.exports = mongoose.model('User', userSchema);
