I have added google code to my service worker but it gives me error in google console...
The error in console Google:
pwaupdate:176 Uncaught (in promise) TypeError: Failed to register a ServiceWorker for scope ('https://myweb.org/') with script ('/pwabuilder-sw.js'): ServiceWorker script evaluation failed
My service worker:
const CACHE = "pwabuilder-offline-page"; const offlineFallbackPage = "/offline.html"; // Install stage sets up the offline page in the cache and opens a new cache self.addEventListener("install", function (event) { console.log("[PWA Builder] Install Event processing"); event.waitUntil( http://caches.open(CACHE).then(function (cache) { console.log("[PWA Builder] Cached offline page during install"); if (offlineFallbackPage === "offline.html") { return cache.add(new Response("TODO: Update the value of the offlineFallbackPage constant in the serviceworker.")); } return cache.add(offlineFallbackPage); }) ); }); //https://developers.google.com/web/updates/2017/02/navigation-preload //Acelerar al trabajador de servicio con precargas de navegación self.addEventListener('fetch', event => { event.respondWith(async function() { // Respond from the cache if we can const cachedResponse = await caches.match(event.request); if (cachedResponse) return cachedResponse; // Else, use the preloaded response, if it's there const response = await event.preloadResponse; if (response) return response; // Else try the network. return fetch(event.request); }()); }); function fromCache(request) { // Check to see if you have it in the cache // Return response // If not in the cache, then return the offline page return http://caches.open(CACHE).then(function (cache) { return cache.match(request).then(function (matching) { if (!matching || matching.status === 404) { // The following validates that the request was for a navigation to a new document if (request.destination !== "document" || request.mode !== "navigate") { return Promise.reject("no-match"); } return cache.match(offlineFallbackPage); } return matching; }); }); } function updateCache(request, response) { return http://caches.open(CACHE).then(function (cache) { return cache.put(request, response); }); }
