What is a .webmanifest file?

A web app manifest (.webmanifest) is a JSON file that describes a Progressive Web App to the browser, declaring its name, icons, theme colors, start URL, and display mode. It enables installation to a device home screen and standalone launching. It is linked from HTML via a manifest link element.

How to use this file

Use an example webmanifest to test PWA installability, manifest JSON parsing, icon and display-mode handling, and browser or auditing tools like Lighthouse.
