How to Register a Service Worker?
To install a service worker you need to kick-start the process by registering it on your page. This tells the browser where your service worker JavaScript file lives.
You can call below register () every time a page loads without concern; the browser will figure out if the service worker is already registered or not and handle it accordingly.
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('/sw.js').then(function(registration) {
// If Registration was successful
console.log('Success Registration - ', registration.scope);
},
function(err) {
// If Registration was failed!
console.log('Failed Registration - ', err);
});
});
}
This code checks to see if the service worker API is available, and if it is, the service worker at /sw.js is registered once the page is loaded.
