SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables web applications to behave like native apps by providing offline access, installability, and reliable background capabilities so users can continue to use core features without a network connection.

Core Features & Use Cases

  • Service Worker Registration & Caching: Register a service worker and implement cache-first or network-fallback strategies to serve assets and pages offline.
  • Web App Manifest & Installability: Configure manifest fields (name, short_name, start_url, display, icons, theme_color) to allow devices to install the app.
  • Install Prompt & Lifecycle: Handle beforeinstallprompt flow to offer a native-like install experience and manage service worker lifecycle events for updates.
  • Push Notifications & Subscriptions: Integrate VAPID-based push subscriptions via the pushManager for user-visible notifications and server-side subscription storage.
  • Use Case: Convert a single-page web dashboard into an installable PWA that caches the dashboard shell, shows an offline fallback, and receives push alerts for important events.

Quick Start

Register a service worker that precaches critical assets, add a web app manifest with start_url and icons, and serve the site over HTTPS to enable offline behavior and installability.

How do I configure a web app manifest to make my web app installable?▼

To make a web app installable, you configure a web app manifest with fields like name, short_name, start_url, display, icons, and theme_color, and serve the site over HTTPS.

How do I handle the beforeinstallprompt event for a progressive web app?▼

Handling the beforeinstallprompt event involves capturing the prompt to offer a native-like install experience, allowing users to install the progressive web app directly from the browser interface.

How do I set up VAPID-based push notifications in a progressive web app?▼

Setting up VAPID-based push notifications involves integrating the pushManager for user-visible notifications and managing server-side subscription storage to deliver background push alerts.

Does my web app need HTTPS hosting to enable offline support and installability?▼

Yes, HTTPS hosting is a strict requirement to register service workers, enable offline support, and satisfy the installability criteria for progressive web applications.

What is the best cache strategy for serving precached assets in a progressive web app?▼

The best approach is applying cache-first strategies for precached critical assets and network-fallback strategies for dynamic content, ensuring reliable offline behavior and an offline fallback page.
