Example 1

Create a file with the name "reqCookies.js" and copy the following code snippet. After creating the file, use the command "node reqCookies.js" to run this code as shown in the example below −

// req.cookies() Method Demo Example

// Importing the express & cookieParser module
var cookieParser = require('cookie-parser');
var express = require('express');

// Initializing the express and port number
var app = express();

// Initializing the router from express
var router = express.Router();
var PORT = 3000;

// Defining the cookieParser to be used
app.use(cookieParser());

// Defining an endpoint
app.get('/api', function (req, res) {
   req.cookies.title='TutorialsPoint';
   console.log(req.cookies);
   res.send();
});
app.listen(PORT, function(err){
   if (err) console.log(err);
   console.log("Server listening on PORT", PORT);
});
