vite-plugin-inject-sw-assets/dist/utils/manifest-utils.js

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

/**
 * Extracts the list of icon file paths from a PWA manifest file.
 * These paths are typically used to avoid re-caching them in the service worker.
 *
 * @param {string} manifestPath - Absolute or relative path to the manifest.webmanifest file
 * @returns {string[]} - Array of icon paths (prefixed with a slash if needed)
 */

    // Read and parse the manifest file as JSON
    const content = JSON.parse(fs.readFileSync(manifestPath, 'utf-8'));
    // Map each icon to its "src" field, ensuring it starts with a leading slash
    return (content.icons || []).map((icon) => icon.src.startsWith('/') ? icon.src : `/${icon.src}`);
