How do you architect an offline-first Vue 3 PWA using vite-plugin-pwa and Workbox caching?
❓ Interview Prompt: Explain Progressive Web Apps (PWA) in Vue 3, vite-plugin-pwa, Workbox caching strategies, and background sync.
Building an offline-first PWA (Progressive Web App) in Vue 3 relies on Service Workers powered by Workbox and 'vite-plugin-pwa'.
Caching Strategies:
•
NetworkFirst: For API data routes (tries network, falls back to IndexedDB cache offline).
•
CacheFirst: For static JavaScript chunks and CSS assets.
•
Background Sync: Queues offline form submissions in IndexedDB and replays them automatically when network connectivity is restored!
Code Implementation Example
javascript
// vite.config.js — PWA Service Worker Config
import { VitePWA } from 'vite-plugin-pwa';
export default {
plugins: [
VitePWA({
registerType: 'autoUpdate',
workbox: {
globPatterns: ['**/*.{js,css,html,ico,png,svg}'],
runtimeCaching: [{
urlPattern: /^https:\/\/api\.example\.com\/.*/i,
handler: 'NetworkFirst',
options: { cacheName: 'api-cache', expiration: { maxEntries: 50 } }
}]
}
})
]
