If you’re building a web application with React, you may need to store user data or state information across different pages or components. To do this, you can use session management techniques like cookies or localStorage.
In this article, we’ll show you how to set session in React using cookies. This will help you keep track of user preferences and data, and personalize their experience on your web application.
What is Session Management?
Session management is the process of storing user data or state information on the server or client side for a certain period of time. This is done to maintain user preferences or data across different pages or components of a web application.
Session management can be achieved using different techniques like cookies, localStorage, sessionStorage, and more. In this article, we’ll focus on using cookies to store session data in React.
Why Use Cookies for Session Management?
Cookies are small pieces of data that are sent from a website and stored on a user’s browser. They’re commonly used for session management because they can store user data across different web pages or components.
Cookies are also easy to use and set up. They can be accessed and modified using JavaScript, making them a great choice for client-side web applications.
How to Set Session in React js using Cookies
To set session data in React using cookies, you’ll need to install the js-cookie package. This package allows you to set, get, and delete cookies in your React application.

To install the js-cookie package, open your terminal and run the following command:
npm install js-cookie
Once the package is installed, you can use the Cookies.set() method to set a cookie with your desired name and value. For example, if you want to store a user’s name as a session variable, you can use the following code:
import Cookies from 'js-cookie';
Cookies.set('username', 'John Doe');
Cookies.set('username', 'John Doe');
This will create a cookie named username with the value John Doe. To access the cookie value in another component or page, you can use the Cookies.get() method:
import Cookies from 'js-cookie';
const username = Cookies.get('username');
console.log(username); // Output: "John Doe"
To delete a cookie, you can use the Cookies.remove() method:
import Cookies from 'js-cookie';
Cookies.remove('username');
This will delete the username cookie from the user’s browser.
Tips for Using Cookies in React
When using cookies for session management in React, there are a few things to keep in mind:
- Make sure to set an expiration date for your cookies to avoid them being stored indefinitely on the user’s browser.
- Don’t store sensitive information like passwords or credit card information in cookies.
- Keep the size of your cookies small to avoid slowing down your web application.
Conclusion
Session management is an important part of building a web application with React. By using cookies, you can store user data or state information across different pages or components.
To set session in React using cookies, you can use the js-cookie package to set, get, and delete cookies in your application. Make sure to follow best practices when using cookies to ensure the security and performance of your web application.
