A web manifest file lists all the information about the website in a JSON format. Having this file is one of the requirements to make the website installable.
It usually resides in the root folder of a web app. It contains useful information, such as the app’s title, paths to different-sized icons that can be used to represent the app on a mobile OS (for example, as the home screen icon), and a background color to use in loading or splash screens. This information is needed for the browser to present the web app properly when installing, and on the home screen.
