How Can We Detect Active Browser Tabs to Optimize Web Resource Usage?

Browser Activity Detection: Determining Active Browser Tabs

In modern web development, it is imperative to conserve resources and prevent unnecessary processing. To achieve this, it is essential to determine whether a browser or tab is active, i.e., visible to the user. This information is crucial for conditionally executing resource-intensive functions, such as animations or background processes.

JavaScript Techniques

One effective approach is to utilize the Page Visibility API. This API provides a simple method to check if a page is hidden from the user. The document.hidden property returns true if the page is not currently visible and false otherwise.

if (!document.hidden) {
    // Execute code when the page is active
}
Copy after login

This method is supported by all modern browsers and is a reliable way to determine page visibility.
