HTML5 Web Workers in NodeJS?

Question

Anyone knows what the status of Web Worker support in NodeJS is? I found a two year old implementation, node-webworkers, but it didn't run with the current build of NodeJS.

Answer 1

Now there is https://github.com/audreyt/node-webworker-threads which appears to be actively maintained.

Answer 2

Worker Threads reached stable status in 12 LTS. Usage example

const {
  Worker, isMainThread, parentPort, workerData
} = require('worker_threads');

if (isMainThread) {
  module.exports = function parseJSAsync(script) {
    return new Promise((resolve, reject) => {
      const worker = new Worker(__filename, {
        workerData: script
      });
      worker.on('message', resolve);
      worker.on('error', reject);
      worker.on('exit', (code) => {
        if (code !== 0)
          reject(new Error(`Worker stopped with exit code ${code}`));
      });
    });
  };
} else {
  const { parse } = require('some-js-parsing-library');
  const script = workerData;
  parentPort.postMessage(parse(script));
}
