I am currently working on service worker to handle push notification in browser. Currently I am having this "SW registration failed error":

SW registration failed with error SecurityError: Failed to register a ServiceWorker: The URL protocol of the current origin ('null') is not supported.

Check client1.html and service-worker.js file below:

service-worker.js

console.log('Started', self);
self.addEventListener('install', function(event) {
  self.skipWaiting();
  console.log('Installed', event);
});
self.addEventListener('activate', function(event) {
  console.log('Activated', event);
});
self.addEventListener('push', function(event) {
  console.log('Push message received', event);
});

client1.html

<!doctype html>
<html>
  <head>
    <title>Client 1</title>
  </head>
  <body>
    <script>
      if('serviceWorker' in navigator){
        // Register service worker
        navigator.serviceWorker.register('service-worker.js').then(function(reg){
          console.log("SW registration succeeded. Scope is "+reg.scope);
        }).catch(function(err){
          console.error("SW registration failed with error "+err);
        });
      }
    </script>
  </body>
</html>

Can anyone help with this issue?

The 1st argument to ServiceWorkerContainer.register is an URL. The error message indicates that your browser is refusing to use a resource because the origin is null - which happens often for local (file://) resources. service-worker.js is local - I'll bet this is why you're getting the cross origin resource issue - Tibrogargan
I do not see any reference to Pusher in the code. Why does this question have the pusher tag? - Alex Booker
I am working on web pusher. This question came while creating web pusher. Do you have any idea how to identify unique browser to push from pusher? I am stuck in that portion. - Saugat Bhattarai
Service worker will work only if you run it on a server. Just by opening the index.html from the finder will not work. You can use python -m SimpleHTTPServer or any to get started. - Harish V

Solved: First thing is service worker only works in secure mode either in https or localhost. It doesnot work in local resources like file:// or http.

and second issue was during registration.

navigator.serviceWorkerContainer
      .register('service-worker.js')
      .then(function(reg){

Use chrome webserver, to run the app or just a simple command in terminal(Mac) would do. python -m SimpleHTTPServer

Please register sw.js in your html page

        <script type="text/javascript">

                navigator.serviceWorker.register('/myproject/scripts/common/pushNotifications/sw.js').then(function(registration) {
                console.log('ServiceWorker registration successful with scope: ', registration.scope);
                     }, function(err) {
                console.log('ServiceWorker registration failed: ', err);
                });
                
        </script>
