What is a webmanifest file?▼

A JSON file that provides information about a web application (name, icons, theme colors) when installed to a mobile home screen.

In Next.js App Router, place favicon.ico, icon.png, and apple-icon.png directly in the /app root directory.

How do you refresh a cached favicon in a browser?▼
