@lucid-softworks/concurrency-limit

Run an array of lazy tasks with bounded concurrency while preserving result order.

import { runWithConcurrency } from "@lucid-softworks/concurrency-limit";

const users = await runWithConcurrency(
  ids.map((id) => () => fetchUser(id)),
  4,
);

Task failures reject the returned promise unchanged. Already-running work is not cancelled.
