Angular Service Worker Life Cycle

Register a Service Worker in Angular

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.
