Single route middleware to check if User is Authenticated using Node.js

Middleware is a function with access to the request object (req), the response object (res),
and the next middleware in the application’s request-response cycle, commonly denoted by a variable named next. You can read more about this Here. route middleware nodejs

Its difficult to call function in each route and check if user authenticated or not so I found the way somewhere where we can use routes
Middleware to prevent calling function each and every routes which I am going to share with you today.

Our Route looks like this:-

var express = require('express');
var router = express.Router();

//all routes
router.get('/home',function (req, res) {

Now create a Route Middleware function to check if user authenticated

function isUserAuthenticated(req,res,next){
//you can check anything heref like req.url ,session ect.

//so let's check if user session exists
//user logged in
return next();
//user not authenticated redirect them to login page or anywhere you want

Now we have the function to check if user authnticated its time to implement that you can use this like below:-

//all routes
router.get('/home', isUserAuthenticated, function (req, res) {
