Service Worker Life Cycle - A service worker has a life cycle that is completely separate from your web apps page.
To install a service worker for our site, we need to register it, which we do in our pages. To Registering a service worker will cause the browser to start the service worker install step in the background process.
Prerequisites to Supports Service workers-
ü Browser support
ü You need HTTPS
How
To Register A Service Worker?
To install a service worker you need to kick
start the process by registering it in 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.
