Local Storage, Offline Capabilities, and APIs in HTML5

Beginner

HTML5 APIs for Native-like Web Applications 🚀

HTML5 brought several APIs that enable web applications to behave more like native apps, including:

  • 💾 Local Storage (localStorage and sessionStorage):
    Enable data persistence on client side without server interaction.

  • 📁 Application Cache (deprecated in favor of Service Workers):
    Allowed offline access.

  • ⚙️ Service Workers:
    Enable background scripts for push notifications, caching, and offline support.

  • 🗄️ IndexedDB:
    Provides a powerful way to store structured data, comparable to a database.

Example: Using localStorage

localStorage.setItem('username', 'JaneDoe');
console.log(localStorage.getItem('username')); // Outputs 'JaneDoe'
