Workbox
Why do we use workbox?
There's lots of complex interactions that are hard to get right [in service workers APi and logic]. Workbox is a set of modules that simplify common service worker routing and caching. Each module available addresses a specific aspect of service worker development. Workbox aims to make using service workers as easy as possible, while allowing the flexibility to accommodate complex application requirements where needed. https://developer.chrome.com/docs/workbox/what-is-workbox/

<?php
/** @var $block \MageSuite\Pwa\Block\Data */
$url = $block->getBaseUrl() . 'service-worker.js';
?>
<script>
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('<?= /* @noEscape */ $url ?>');
}
</script>
|
