Manifest.json

A **manifest.json** file is a metadata file used by web applications, browser extensions, and progressive web apps (PWAs) to describe essential information about the project. It typically contains details such as the app’s name, version, description, permissions, icons, and entry points. For example, in a web extension, it tells the browser how to load and run the extension, while in a PWA, it defines how the app should appear and behave when installed on a user’s device.
