Running a TypeScript worker in Node.js

It's really hard to get new Worker() from node:worker_threads to work when running code via tsx. I finally got an example working. Here's how to do it:

import {Worker} from 'node:worker_threads';

const workerPath = import.meta.resolve('./sample-worker.js');
const worker = import.meta.filename.endsWith('.ts')
    ? new Worker(
          `import('tsx/esm/api').then(({ register }) => { register(); import('${workerPath}') })`,
          {
              eval: true,
          },
      )
    : new Worker(workerPath);
