Which browsers support the HTML5 History API?

The HTML5 History API allows web applications to manipulate browser history programmatically, enabling single-page applications to update URLs without full page reloads. Understanding browser support is crucial for implementing this feature effectively.

Browser Support Overview

The HTML5 History API is now widely supported across modern browsers. WebKit-based browsers and Firefox 4 were among the first to implement this feature, but support has expanded significantly since then.

Supported Browsers

• Firefox: Version 4 and above
• Google Chrome: All versions (since Chrome 5)
• Internet Explorer: Version 10 and above
• Microsoft Edge: All versions
• Safari: Version 5 and above
• Opera: Version 11.50 and above
• iOS Safari: iOS 4.2 and above
• Android Browser: Android 2.2 and above

Checking Browser Support

You can programmatically check for HTML5 History API support using feature detection:

function supportsHistoryAPI() {
    return !!(window.history && window.history.pushState);
}

// Check support
if (supportsHistoryAPI()) {
    console.log("HTML5 History API is supported");
    // Use pushState, replaceState, popstate events
} else {
    console.log("HTML5 History API not supported");
    // Fallback to hash-based routing
}

Key History API Methods

When browser support is available, you can use these main methods:

// Add new history entry
history.pushState({page: 'home'}, 'Home Page', '/home');

// Replace current history entry
history.replaceState({page: 'about'}, 'About Page', '/about');

// Listen for back/forward button
window.addEventListener('popstate', function(event) {
    console.log('State:', event.state);
});

Legacy Browser Considerations

For applications that need to support older browsers (IE 9 and below), consider using polyfills or fallback solutions like hash-based routing (#/page) instead of the History API.

Conclusion

The HTML5 History API enjoys excellent support across all modern browsers. With over 95% global browser support, it's safe to use in production applications with minimal fallback considerations for legacy browsers.
