useWorker

To facilitate the use node's worker thread's with async/await. This helper passes data to a specified worker file most likely for a heavy computation.

It expects an object with 2 properties:

• path (string), that is; the relative path to the worker file
• data (any), any JSON serializable value you wish to pass to a worker file

Only the data would be passed to the worker file

const data = await useWorker({
  path: "./test-worker.js",
  data: { message: "data to process" },
});

The worker file:

const { parentPort, workerData } = require("worker_threads");

(() => {
  const data = JSON.parse(workerData);

  data.isProcessed = true;

  parentPort.postMessage(data);
})();
