What is Service Worker

A Service Worker is a script that the browser runs in the background, separate from a web page, allowing for features that don't need a web page or user interaction. It is primarily used to enable offline experiences, intercept network requests, and take advantage of cache storage to improve performance and reliability.

Service Workers are event-driven and can respond to various events such as fetching resources, installing, and activating. They offer powerful capabilities like push notifications and background sync, enhancing the overall user experience.

To implement a Service Worker, you should register it in your JavaScript code. Here is a simple example:

if ('serviceWorker' in navigator) { window.addEventListener('load', function() { navigator.serviceWorker.register('/service-worker.js').then(function(registration) { console.log('Service Worker registered with scope:', registration.scope); }, function(error) { console.log('Service Worker registration failed:', error); }); }); }
