新增于: v10.5.0
任意的 JavaScript 值，其中包含传给该线程的 Worker 构造函数的数据的克隆。 根据 HTML 结构化克隆算法，数据如同使用 postMessage() 一样被克隆。 const { Worker, isMainThread, workerData } = require('node:worker_threads'); if (isMainThread) { const worker = new Worker(__filename, { workerData: 'Hello, world!' }); } else { console.log(workerData); // 打印 'Hello, world!'。 } Added in: v10.5.0An arbitrary JavaScript value that contains a clone of the data passed to this thread's Worker constructor. The data is cloned as if using postMessage(), according to the HTML structured clone algorithm. const { Worker, isMainThread, workerData } = require('node:worker_threads'); if (isMainThread) { const worker = new Worker(__filename, { workerData: 'Hello, world!' }); } else { console.log(workerData); // Prints 'Hello, world!'. } |
