Service Worker Registration Failed
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?
Answer
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){
