This revolutionary technology acts as a proxy between your PWA and the network, allowing it to respond to user interactions even when there is no internet connection.

What Service Workers Are and How They Function

Service Workers are a type of web worker, JavaScript files that run separately from the main browser thread. They intercept network requests, acting as a proxy server between web applications, the browser, and the network (when available).

These workers function by listening for certain events, such as network requests or push notifications, and respond accordingly. This capability allows them to cache your app’s assets and serve them directly from the cache rather than the network – a critical feature enabling your Progressive Web App (PWA) to function offline.

Implementing a Service Worker For Offline Capabilities

Implementing a service worker to enable offline capabilities in your Progressive Web App (PWA) involves key steps. First, you need to register the service worker. This is done within the main JavaScript file of your PWA. Registration tells the browser where your service worker JavaScript file lives.

Registration of Service Worker


if (‘service worker in navigator) {


.then(function(registration) {

console.log(‘Service Worker registration successful with scope: ‘, registration.scope);


.catch(function(err) {

console.log(‘Service Worker registration failed: ‘, err);




Once registered, the service worker undergoes an installation process. During this phase, it’s common to cache your app’s static assets.

Installation of Service Worker


self.addEventListener(‘install’, function(event) {

event.wait until(

caches.open(‘my-site-cache’).then(function(cache) {

return cache.addAll([










After installation, the service worker becomes active and controls developing your PWA’s pages, allowing it to intercept network requests.

Fetch Events Handling


self.addEventListener(‘fetch’, function(event) {



.then(function(response) {

if (response) {

return response;


return fetch(event.request);





When the user is offline, the service worker intercepts fetch requests and serves the assets directly from the cache, providing an uninterrupted user experience.

Creating a Web App Manifest

The Web App Manifest is crucial in developing your Progressive Web App (PWA). It’s essentially a JSON file that provides a centralized place to define how your app should behave when installed on the user’s device.
