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

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

/**
 * Writes a JavaScript file that defines a global variable with the list of assets to precache.
 * This file is intended to be imported or referenced by the service worker.
 *
 * @param {string} filePath - The path where the output file should be written (e.g., "dist/sw-assets.js")
 * @param {AssetEntry[]} assets - The list of assets to inject, each with a `url` and optional `revision`
 */
// Import Node's filesystem module to write files to disk

    const content = `self.__INJECTED_ASSETS__ = ${JSON.stringify(assets, null, 2)};`;
    // Write the content to the specified file
    fs.writeFileSync(filePath, content);
