Implementing Offline Capabilities

To implement offline capabilities in your web application, you can use Service Workers. Here is an example of how to set it up:


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

            // Inside service-worker.js
            self.addEventListener('install', function(event) {
                event.waitUntil(
                    caches.open('my-cache-v1').then(function(cache) {
                        return cache.addAll([
                            '/',
                            '/index.html',
                            '/styles.css',
                            '/script.js'
                        ]);
                    })
                );
            });

            self.addEventListener('fetch', function(event) {
                event.respondWith(
                    caches.match(event.request).then(function(response) {
                        return response || fetch(event.request);
                    })
                );
            });
