I'm trying to register a service worker but I have the following error:
Failed to register a ServiceWorker: The URL Protocol of the current origin ('null') is not supported
I'm under localhost with node js and I have my index.html and service-worker.js in the same folder
index.html
<!doctype html>
<html>
<head>
<title>TryService</title>
</head>
<body>
PROVA SITO CON SERVICE WORKER
<script>
if('serviceWorker' in navigator){
// Register service worker
navigator.serviceWorker.register('service-worker.js').then(function(reg){
console.log("Registration OK!. Scope is "+reg.scope);
}).catch(function(err){
console.error("Registration FAILED! "+err);
});
}
</script>
</body>
</html>
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);
});
How can I fix it? Thank you in advance!
