Using session storage for user tracking in JavaScript

In modern web development, it’s crucial to track user behavior to gain insights and improve user experience. One way to track users is by utilizing session storage in JavaScript. Session storage provides a way to store data on the client-side browser for the duration of a session.

Here’s how you can use session storage to track user interactions:

1. Storing User Tracking Data

To store user tracking data, you can use the sessionStorage object provided by the browser’s JavaScript API. The sessionStorage object allows you to set and get values associated with a specific session.

// Storing user tracking data
sessionStorage.setItem('user_id', '12345');
sessionStorage.setItem('last_visited_page', '/home');
sessionStorage.setItem('number_of_page_views', '5');

In the example above, we store the user’s unique ID, the last visited page, and the number of page views using the setItem() method of the sessionStorage object.

2. Retrieving User Tracking Data

Once the user tracking data is stored, you can retrieve it at any time during the session using the getItem() method.

// Retrieving user tracking data
const userId = sessionStorage.getItem('user_id');
const lastVisitedPage = sessionStorage.getItem('last_visited_page');
const numberOfPageViews = sessionStorage.getItem('number_of_page_views');

In the example above, we retrieve the stored data by passing the corresponding key to the getItem() method. The retrieved values are then assigned to variables for further use in your application.

3. Updating User Tracking Data

As users interact with your website, you can update the stored tracking data by using the same setItem() method.

// Updating user tracking data
const newPage = '/about';
const currentNumberOfViews = Number(sessionStorage.getItem('number_of_page_views'));
sessionStorage.setItem('last_visited_page', newPage);
sessionStorage.setItem('number_of_page_views', currentNumberOfViews + 1);

In the example above, we update the last visited page to /about, and increment the number of page views by 1.

Conclusion

Using session storage for user tracking in JavaScript is a simple and effective way to gather insights about user behavior on your website. By storing and retrieving data during a session, you can gain valuable information that can help improve user experience and impact business decisions.
