async-promise-queue

library1.0.5jsnpmunverified

Wrapper around async.queue that provides a promise-based API for queueing asynchronous tasks with concurrency control. Current stable version: 1.0.5. Release cadence: infrequent, last updated in 2019. Key differentiators: automatically waits for pending work to finish before rejecting on failure, preventing runaway tasks; also exports a reference to the async module it depends on. Suitable for Node.js environments with Promise-based workflows.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

queue

✓ import queue from 'async-promise-queue'

✗ const { queue } = require('async-promise-queue')

Default export is a function; named export 'queue' does not exist.

async

✓ import { async } from 'async-promise-queue'

✗ const async = require('async-promise-queue/async')

The 'async' property is a named export, not a submodule.

default import (function)

✓ const queue = require('async-promise-queue')

✗ const { async } = require('async-promise-queue')

Default CommonJS import is the queue function; destructuring gives async reference.

Shows basic usage: import default function, create a worker that returns a promise, enqueue tasks with concurrency limit, and handle completion or errors.

import queue from 'async-promise-queue'; const worker = (task) => { console.log('Processing', task.file); return new Promise((resolve) => setTimeout(resolve, task.duration)); }; const tasks = [ { file: 'a.txt', duration: 100 }, { file: 'b.txt', duration: 200 }, ]; queue(worker, tasks, 2) .then(() => console.log('All done')) .catch((err) => console.error('Error:', err));

Debug

Known issues

gotchaThe default export is a function, not a named export. CommonJS users often destructure incorrectly.

fix

Use `const queue = require('async-promise-queue')` for CommonJS; `import queue from 'async-promise-queue'` for ESM.

affects: *

gotchaThe worker function must return a promise (or be wrapped with async.asyncify). If a synchronous error is thrown, it may not be caught properly.

fix

Wrap synchronous work in a Promise, or use `queue.async.asyncify(worker)`.

affects: *

deprecatedThe package depends on the `async` module v2.x which may lag behind the latest async releases. No TypeScript types included.

fix

Consider alternative libraries like `p-queue` for better TypeScript support and active maintenance.

Errors

Common errors & fixes

TypeError: queue is not a function

Using named import destructuring on CommonJS default export.

fix

Use `const queue = require('async-promise-queue')` or `import queue from 'async-promise-queue'`.

Error: worker is not a function

Passing an async/await function directly without wrapping in asyncify; the library expects a function that takes (task, callback).

fix

Wrap your worker with `queue.async.asyncify(worker)` if using promises.

TypeError: Cannot read property 'async' of undefined

Importing the module incorrectly in an environment that doesn't support module resolution.

fix

Ensure the package is installed and imported correctly with proper module system (require vs import).
