@jdsalasc/solvejs-async

Zero-dependency async/concurrency utilities for JavaScript and TypeScript.

Utilities

• sleep
• timeout
• retry
• pMap
• debouncePromise
• throttlePromise

When to use this package

Use it when you need predictable retry logic, promise time limits, and controlled async concurrency without adding heavy helper libraries.

Limitations and Constraints

• throttlePromise drops calls made during the throttle window.
• debouncePromise cancels previous pending calls with a rejection.
• Queueing/rate-limit orchestration is intentionally out of scope for now.

Install

npm i @jdsalasc/solvejs-async

Quick example

import { retry, timeout, pMap } from "@jdsalasc/solvejs-async";

const data = await retry(
  () => timeout(fetch("https://api.example.com/items").then((r) => r.json()), 3000),
  { retries: 2, delayMs: 200, backoffFactor: 2 }
);

const ids = await pMap(data.items, async (item) => item.id, { concurrency: 4 });
