404 error when trying to register serviceWorker

Question

I get this error when trying to register the service worker:

Failed to register a ServiceWorker: A bad HTTP response code (404) was gwreceived when fetching the script.

I'm working with ionic and this is what I have in the app.js:

   if ('serviceWorker' in navigator) {       navigator.serviceWorker.register('service-worker.js').then(function(registration) {       console.log('ServiceWorker registration successful with scope: ', registration.scope);     }).catch(function(err) {       //registration failed :(       console.log('ServiceWorker registration failed: ', err);     });   }else {     console.log('No service-worker on this browser');   } 

On the directory I have the service-worker.js file right next to the app.js on the same folder.

Using latest chrome version on ubuntu desktop.

You mention that you have service-worker.js in the same directory as app.js, but the URL passed to .register() is relative to the HTML document's path. You need to make sure your service-worker.js file is in the same directory as the .html file corresponding to the page you're on.
