To configure how the app should be installed and displayed
The Web App Manifest is a JSON file that defines how the PWA should behave when installed on a device. It specifies: 1) App name and icons for the home screen, 2) Start URL and display mode (e.g., standalone, fullscreen), 3) Theme and background colors for a native feel, 4) Other metadata that helps create an app-like experience.
