How to use the @parcel/cache function in @parcel/cache

let lockFile = null;
  let rootFileName = path.basename(projectRootFile);
  if (LOCK_FILE_NAMES.includes(rootFileName)) {
    lockFile = projectRootFile;
  }
  let projectRoot = path.dirname(projectRootFile);

  let outputCwd = outputFS.cwd();
  let cacheDir =
    // If a cacheDir is provided, resolve it relative to cwd. Otherwise,
    // use a default directory resolved relative to the project root.
    initialOptions.cacheDir != null
      ? path.resolve(outputCwd, initialOptions.cacheDir)
      : path.resolve(projectRoot, DEFAULT_CACHE_DIRNAME);

  let cache = new Cache(outputFS, cacheDir);

  let mode = initialOptions.mode ?? 'development';
  let minify = initialOptions.minify ?? mode === 'production';

  return {
    config: initialOptions.config,
    defaultConfig: initialOptions.defaultConfig,
    patchConsole:
      initialOptions.patchConsole ?? process.env.NODE_ENV !== 'test',
    env:
      initialOptions.env ??
      (await loadDotEnv(inputFS, path.join(projectRoot, 'index'))),
    mode,
    minify,
    autoinstall: initialOptions.autoinstall ?? true,
    hot: initialOptions.hot ?? false,
