threads-esm

Very simple worker thread abstraction for ts-node ESM builds.

Couldn't get ts-node ESM workers to work with threads.js, and it doesn't look like I'm alone.

I threw this together as a quick alternative for what I needed.

Install

``bash
yarn add threads-esm
`

or

`bash
npm install threads-esm
`

Example

This basic example can be run using the example script (yarn example or npm run example).

$3

`ts
interface ExampleWorker {
add: (a: number, b: number) => Promise;
subtract: (a: number, b: number) => number;
foo: string;
}
`

$3

`ts
import { spawn } from 'threads-esm';

const worker = await spawn(new URL('./worker.mts', import.meta.url));

// an async function that returns the result of the add function
const result1 = await worker.add(1, 2);

// an async function that returns the result of the subtract function
const result2 = await worker.subtract(1, 2);

// an async function that returns the value of foo property
const result3 = await worker.foo();
`

$3

`ts
import { expose } from 'threads-esm';

expose({
// A function that returns a promise of a number
add: (a: number, b: number): Promise => Promise.resolve(a + b),

// A function that returns a number
subtract: (a: number, b: number): number => a - b,

// A property that is a string
foo: 'bar'
});
