PWA_ENGINEERING

The Web.
Unbound.

We architect Progressive Web Applications that deliver native-app experiences directly through the browser, complete with offline support, push notifications, and home screen installation.

service-worker.ts

import { precacheAndRoute } from 'workbox-precaching';

import { registerRoute } from 'workbox-routing';

// Offline-first strategy

precacheAndRoute(self.__WB_MANIFEST);

registerRoute(

({ request }) => request.destination === 'image',

new CacheFirst({

cacheName: 'images',

plugins: [new ExpirationPlugin({ maxEntries: 50 })],

})

);

System Architecture

Service Workers.

The core of our PWA architecture relies on highly optimized Service Workers acting as network proxies. They intelligently cache assets, intercept requests, and serve data instantly, regardless of the user's network connection.

01

Cache API Strategies

Implementing complex Stale-While-Revalidate and Cache-First algorithms to guarantee sub-second load times on returning visits.

02

Push Notifications

Integrating the Web Push API to send real-time, high-engagement notifications to your users, even when the browser is closed.

03

App Manifest Configuration

Structuring the web app manifest to ensure the application is perfectly installable on Android, iOS, and Desktop environments.
