PWA Manifest Essentials
The web app manifest is a JSON file that tells the browser about your Progressive Web App and how it should behave when installed. Key fields include name, short_name, start_url, display mode (standalone, fullscreen, minimal-ui, browser), theme_color, background_color, and icons array. A properly configured manifest enables Add to Home Screen prompts on mobile and desktop.
