How is it used?

Run multiple promise-returning & async functions with limited concurrency

asyncLimit

import { asyncLimit } from "@comodinx/async-helpers";

const limit = asyncLimit(1);

const input = [
	limit(() => fetchSomething('foo')),
	limit(() => fetchSomething('bar')),
	limit(() => doSomething())
];

// Only one promise is run at once
const result = await Promise.all(input);
console.log(result);

asyncLimitFn

import { asyncLimitFn } from "@comodinx/async-helpers";

const limitedFunction = asyncLimitFn(async () => {
	return doSomething();
}, {concurrency: 1});

const input = Array.from({length: 10}, limitedFunction);

// Only one promise is run at once.
await Promise.all(input);
