vite-plugin-inject-sw-assets/dist/utils/file-scanner.js

A Vite plugin that injects static assets into a custom service worker for use with injectManifest (ideal for Workbox + vite-plugin-pwa setups).

/**
 * Scans the output directory for static assets to be injected into the service worker.
 *
 * @param {string} distDir - The build output directory to scan (e.g., "dist")
 * @param {string[]} extensions - List of file extensions to include (e.g., ["png", "json"])
 * @param {string[]} excluded - List of file URLs to exclude (e.g., icons from manifest)
 * @returns {AssetEntry[]} - List of asset entries with `url` and `revision`
 */
