Making a PWA Installable: Web App Manifest, Install Flows, navigator.install and App Badging
What makes a PWA installable is its manifest: write the id once and keep it, separate any and maskable icons, show the install offer in Chromium with beforeinstallprompt only after the user has seen some value, and give Safari users Add to Home Screen instructions. With real output from Chromium 158 and WebKit we show the identity calculation, the installability check, the errors of navigator.install() and App Badging for unread orders.
