Node.js Cookies Tutorial: How to Create and Send Cookies in Node.js

Learn how to create and send cookies in Node.js using the express framework. A step-by-step guide to master cookies and sessions in Node.js

To get started, you will need to have Node.js and npm (Node Package Manager) installed on your machine. Once you have those setup, you can create a new project directory and initialize it with npm by running the command npm init -y. This will create a package.json file in your project directory.

Next, you will need to install the express framework by running the command npm install express. This will add the express package to your project dependencies. Once the framework is installed, you can require it in your server file like this: const express = require('express');.

After that, you can use the res.cookie() method provided by the express framework to create and send cookies to the client. The res.cookie() method takes three arguments: the cookie name, the cookie value, and an options object. You can use the options object to set additional properties on the cookie such as the expiration date, httpOnly option, path, domain, etc.

For example, to create and send a cookie named "session" with a value of "abc123" and an expiration date of 7 days from now, you can use the following code:

res.cookie('session', 'abc123', {
maxAge: 60 * 60 * 24 * 7, // expires in 7 days
httpOnly: true
});

You can also use req.cookies property to retrieve the cookies sent by the client.

This is a basic example of how to create and send cookies in Node.js using the express framework. For more information on working with cookies in express, you can refer to the official express documentation: https://expressjs.com/en/4x/api.html#...

In summary, in this video, we have explained the basic steps to create and send cookies in Node.js using the res.cookie() method provided by the express framework, explained the important options available to set while sending the cookie and also explained how to retrieve the cookies on the client side using req.cookies property.
