مرجع واجهة ⁦node:worker_threads⁩

يتضمن نطاق الأسماء ⁦Worker⁩ و⁦MessageChannel⁩ و⁦MessagePort⁩ و⁦BroadcastChannel⁩ والبيانات الوصفية للخيوط وبيانات البيئة وعلامات النقل.

يُبقي العامل الجاري ⁦elide run⁩ حيًّا إلى أن يخرج أو يُنهى:

import { Worker } from "node:worker_threads";

const worker = new Worker(
  "require('node:worker_threads').parentPort.postMessage('done')",
  { eval: true },
);
worker.on("message", (msg) => {
  console.log(msg); // done
  worker.terminate();
});

يحدد ⁦--limit=workers=COUNT⁩ سقفًا لعدد العمال الذين يمكن للسكربت بدؤهم؛ راجع عزل نظام الملفات.
