1. 2.x pwa.api.php \hook_pwa_cache_urls_alter()

Alters cached urls list for the service worker file.

This hook allows adding or removing urls to the whitelist for the cache urls. This is the same as the "URLs to cache on install" list on the service worker admin page.

After you make your modifications you do NOT need to return the results. Since $cacheUrls is passed by reference, any changes made to $cacheUrls are automatically registered.

Parameters

array &$cacheUrls: List of urls to cache.

\Drupal\Core\Cache\CacheableMetadata $cacheableMetadata: Cacheability metadata.
