In modern web applications, it is crucial to provide users with an intuitive and seamless browsing experience. One aspect of this user experience is the ability for users to navigate back and forth between pages they have previously visited. One way to achieve this is by implementing a browsing history feature.

In this blog post, we will explore how to use session storage to store and manage user browsing history in a web application.

What is Session Storage?

Session storage is a web API that allows you to store data on the client-side browser for a specific session. The data stored in session storage is available only within the current browsing session and is automatically cleared when the session ends.

Storing User Browsing History

To implement browsing history using session storage, we need to keep track of the page URLs visited by the user and store them in session storage as an array.

Here’s an example code snippet in JavaScript that demonstrates how to store the user’s browsing history:

// Check if session storage is supported by the browser
if (typeof sessionStorage !== 'undefined') {
  // Get the existing browsing history from session storage
  let history = JSON.parse(sessionStorage.getItem('history')) || [];

  // Get the current page URL
  const currentPage = window.location.href;

  // Add the current page URL to the browsing history
  history.push(currentPage);

  // Limit the history length to a certain number, e.g., 10
  const maxLength = 10;
  if (history.length > maxLength) {
    history.shift(); // Remove the oldest URL from history
  }

  // Store the updated browsing history in session storage
  sessionStorage.setItem('history', JSON.stringify(history));
}

In the above code, we first check if the browser supports session storage. If it does, we retrieve the existing browsing history from session storage or initialize it as an empty array. We then retrieve the current page URL using window.location.href and add it to the history array. We can also limit the length of the history array to avoid storing an excessive amount of data.

Finally, we store the updated browsing history back in session storage by using sessionStorage.setItem().

Utilizing the Browsing History

Now that we have successfully stored the user’s browsing history in session storage, we can utilize this information to enhance the web application’s user experience. Some potential use cases include:

1. Implementing a “Back” button that allows users to easily navigate to previous pages.
2. Displaying a list of recently visited pages for quick access.
3. Providing personalized recommendations based on the user’s browsing history.

By leveraging the browsing history data stored in session storage, you can create a more user-friendly and personalized web experience for your users.

Conclusion

Using session storage is a simple and effective way to store and manage user browsing history in a web application. By incorporating this feature, you can enhance the user experience and provide seamless navigation between pages. Remember to handle potential limitations of session storage, such as the amount of data that can be stored, to ensure optimal performance.
