PWA

This is a PWA demo. It is 11:33 in the morning. Your screen is nice.

A progressive web app is:

• an application built using web platform technologies,
• but provides a user experience like that of a platform specific application
• it can run on multiple platforms and devices from a single codebase
• can be installed on the device,
• can operate while offline and in the background,
• and can integrate with the device and with other installed applications.

Installability requirements:

• Web app manifest: JSON file linked in HTML header that tells the browser how the PWA should appear and behave on the device. Certain fields like description and icons in manifest file are required.
• must be served over HTTPS, HTTP only works on localhost. File protocol not supported at all.

Server workers are not required, but you must provide offline experience somehow.

If everything is fine, your PWA should be installable from the interface of your web browser somehow. Unles oligarchy interferes.

This application is brown in a browser and blue when fullscreen. It is green when installed on a device and red when minimal gui is shown there.
