help you fix your problem It sounds like you want a "Network First" strategy in your Service Worker. This is documented by Jake Archibald for Google. You can read about it here. This type of Service Worker checks for files on the network before looking at the offline cache.

this will help As far I can understand the first one does not wait until the ServiceWorkerRegistration has an active ServiceWorker. The last one does.

I wish did fix the issue. So it turns out this just indicates there is a JS error in the Service Worker code itself, so the registration couldn't complete.
Load chrome://serviceworker-internals/ and check 'Open DevTools window and pause JavaScript execution on Service Worker startup for debugging.'

if ($_SERVER['HTTP_HOST'] == 'localhost')

    // do something

    // do something else
$whitelist = array( '' ); 

if(!in_array($_SERVER['REMOTE_ADDR'], $whitelist))

this will help I have achieved my desired result with the following code underneath the following comments.
code :
// Cache signature post request
    //This retrieves all the information about the POST request including the formdata body, where the URL contains updateSignature.
// Resubmit offline signature requests
    //This resubmits all cached POST results and then empties the array.

self.addEventListener('fetch', function(event) {
    // Intercept all fetch requests from the parent page
        .then(function(response) {
            // Cache signature post request
            if (event.request.url.includes('updateSignature') && !navigator.onLine) {
                var request = event.request;
                var headers = {};
                for (var entry of request.headers.entries()) {
                    headers[entry[0]] = entry[1];
                var serialized = {
                    url: request.url,
                    headers: headers,
                    method: request.method,
                    mode: request.mode,
                    credentials: request.credentials,
                    cache: request.cache,
                    redirect: request.redirect,
                    referrer: request.referrer
                request.clone().text().then(function(body) {
                    serialized.body = body;
            // Immediately respond if request exists in the cache and user is offline
            if (response && !navigator.onLine) {
                return response;
            // Resubmit offline signature requests
            if(navigator.onLine && callsToCache.length > 0) {
                callsToCache.forEach(function(signatureRequest) {
                    fetch(signatureRequest.url, {
                        method: signatureRequest.method,
                        body: signatureRequest.body
                callsToCache = [];

            // IMPORTANT: Clone the request. A request is a stream and
            // can only be consumed once. Since we are consuming this
            // once by cache and once by the browser for fetch, we need
            // to clone the response
            var fetchRequest = event.request.clone();

            // Make the external resource request
            return fetch(fetchRequest).then(
                function(response) {
                // If we do not have a valid response, immediately return the error response
                // so that we do not put the bad response into cache
                if (!response || response.status !== 200 || response.type !== 'basic') {
                    return response;

                // IMPORTANT: Clone the response. A response is a stream
                // and because we want the browser to consume the response
                // as well as the cache consuming the response, we need
                // to clone it so we have 2 stream.
                var responseToCache = response.clone();

                // Place the request response within the cache
                .then(function(cache) {
                    if(event.request.method !== "POST")
                        cache.put(event.request, responseToCache);

                return response;
