VueJs Web Applications is Failed Authenticate User - node.js

Question

I creating e commerce project . I want to user must have account in order to proceed the checkout process . I am able to create new user with the database but the problem is even the user is login and click buy button ,Still it is showing message user must be login. I want once the user is login then user will be able to buy products..
Here is my app.js code .
'use strict';
var debug = require('debug');
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var { User } = require('./db');
var session = require('express-session');
var passport = require('./passport');
var routes = require('./routes/api/index');
//var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');
// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/api', require('./routes/api').route);
//app.use('/', routes);
//app.use('/users', users);
app.use(session({
secret: 'some very very secret thing',
resave: false,
saveUninitialized: true
}));
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.use(passport.initialize());
app.use(passport.session());
app.post('/signup', (req, res) => {
User.create({
username: req.body.username,
password: req.body.password
}).then((user) => {
if (user) {
res.redirect('/signin.html');
}
}).catch((err) => res.send("ERROR CREATING USER"));
});
app.post('/signin', passport.authenticate('local', {
failureRedirect: '/signin.html',
// successRedirect: 'profile'
successRedirect: '/index.html'
}));
// catch 404 and forward to error handler
app.use(function (req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function (err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function (err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
app.set('port', process.env.PORT || 3000);
var server = app.listen(app.get('port'), function () {
debug('Express server listening on port ' + server.address().port);
});
Here is the user.js code .
var route = require('express').Router();
var { User } = require('../../db');
var session = require('express-session');
var passport = require('../../passport');
route.use(session({
secret: 'some very very secret thing',
resave: false,
saveUninitialized: true
}));
route.use(passport.initialize());
route.use(passport.session());
route.post('/signup', (req, res) => {
User.create({
username: req.body.username,
password: req.body.password
}).then((user) => {
if (user) {
res.redirect('/signin.html');
}
}).catch((err) => res.send("ERROR CREATING USER"));
});
route.post('/signin', passport.authenticate('local', {
failureRedirect: '/signin.html',
// successRedirect: 'profile',
successRedirect: '../../index.html'
}));
route.get('/profile', (req, res) => {
//Available to only logged in people
// Data is different (each user sees own profile)
// console.log(req)
if (req.user) {
res.json(req.user);
} else {
res.send("YOU ARE NOT LOGGED IN");
}
});
exports = module.exports = route;

Here is screen shot even user is login still displaying message first you must login.
