Minimal needed fs context to get TypeScript Working

[frank-dspeed]

watcher supports

• (eg on OS that dont support recursive watch using fs.watch use fs.watchFile) // which is same behaviour when recursive: true is passed to fs.watch // Use notifications from FS to watch with falling back to fs.watchFile // Use notifications from FS to watch with falling back to fs.watchFile // Node 4.0 fs.watch function supports the "recursive" option on both OSX and Windows // Node 4.0 fs.watch function supports the "recursive" option on both OSX and Windows // so instead of throwing error, use fs.watchFile // Watch the file or directory using fs.watchFile since fs.watch threw exception

  # minimum fs
  # All Calls from tsc.js to fs without resolve
  fs.existsSync(traceDir)
  fs.mkdirSync(traceDir, { recursive: true });
  fs.openSync(tracePath, "w");
  fs.writeSync(traceFd, `[\n`);
  fs.closeSync(traceFd);
  fs.writeFileSync(legendPath, JSON.stringify(legend));
  fs.statSync(path);
  _fs.watchFile(fileName, { persistent: true, interval: pollingInterval }, fileChanged);
  fs.unwatchFile(fileName, fileChanged)
  const presentWatcher = _fs.watch(fileOrDirectory, options, isLinuxOrMacOs ?
  fs.readFileSync(fileName);
  const entries = _fs.readdirSync(path || ".", { withFileTypes: true });
  fs.realpathSync(path);
  fs.utimesSync(path, time, time);
  fs.unlinkSync(path);
