Manifest JSON
Manifest JSON is a JSON-based configuration file used in web development to define metadata and settings for web applications, particularly Progressive Web Apps (PWAs) and browser extensions. It specifies properties such as the app's name, icons, start URL, display mode, and permissions, enabling features like offline functionality, home screen installation, and enhanced user experience. This file is essential for making web apps behave more like native applications on various platforms.
Developers should learn and use Manifest JSON when building Progressive Web Apps (PWAs) to enable features like offline access, push notifications, and home screen installation, which improve user engagement and performance. It is also crucial for creating browser extensions in Chrome, Firefox, and Edge, as it defines the extension's metadata, permissions, and background scripts. Use cases include e-commerce sites, productivity tools, and any web application aiming for a native-like experience across devices.
