Web App Manifest
The Web App Manifest is a JSON file that provides metadata about a Progressive Web App (PWA), enabling it to be installed on a user's device and behave like a native application. It specifies properties such as the app's name, icons, start URL, display mode, and theme colors, allowing developers to control how the app appears and functions when launched from the home screen. This standard is part of the web platform, supported by modern browsers, to enhance the user experience of web applications.
Developers should learn and use the Web App Manifest when building Progressive Web Apps (PWAs) to enable installation capabilities and improve user engagement, as it allows web apps to be added to home screens and run in standalone modes without browser UI. It is essential for creating app-like experiences on mobile and desktop, supporting features like offline access, push notifications, and responsive design, making it crucial for modern web development targeting cross-platform deployment.
