Link a Web App Manifest for installability

A Web App Manifest is the minimum requirement for a site to be installable as a Progressive Web App. Installed PWAs launch in their own window, appear in app switchers, and can receive push notifications. Even for non-PWA sites, the manifest improves the experience when users bookmark to their home screen and provides metadata for browser share dialogs.

Quick Reference

• Link manifest.json with
• Include name, short_name, icons (192px and 512px minimum), and start_url
• Set display: standalone to hide browser chrome when launched from home screen
• Set theme_color to control the browser address bar and OS taskbar color

Check

Check if this HTML file has a Web App Manifest linked. If so, verify the manifest has all required fields for installability.

Fix

Create a minimal Web App Manifest with the required fields and link it from the HTML head.
