Function default

Installs the service worker and automatically prefetches all links on the page that match the rules with the 'max_age' and 'service_worker_max_age' features.

It also immediately prefetches all URLs specified in prefetchURLs. All links whose href attribute matches one of the specified prefetchPatterns will be watched and when a matching link is visible in the viewport, the destination URL will be prefetched and added to the cache. See InstallOptions for more details.

Example of simple installation

 import { install } from '@edgio/prefetch/window';

// Install the service worker
document.addEventListener('DOMContentLoaded', () => {
  install();
});

Example of installation with advanced config

 import { install } from '@edgio/prefetch/window';

// Install the service worker
document.addEventListener('DOMContentLoaded', () => {
  install({
     // Prefetches the specified URLs immediately after installation
     prefetchURLs: [
       '/some/url'
     ],
     // Watches all links on the page that match specified regex patterns and prefetches their destination URL
     // when the link becomes visible in the viewport
     prefetchPatterns: [
       //products/(.+)/
     ]
  });
});
