library1.1.33jsnpmunverified

A small JavaScript library for queuing promises, allowing control over concurrency and priority. Current stable version: 1.1.33. Simple API with support for options like maxOperationCount and task priority. Less feature-rich than async.queue but lightweight and easy to integrate.

Code

Verified usage

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

Puqeue

✓ import Puqeue from 'puqeue'

✗ const Puqeue = require('puqeue')

ESM default import is recommended; CommonJS require also works but may cause issues in ESM contexts.

Puqeue

✓ import { default as Puqeue } from 'puqeue'

✗ import { Puqeue } from 'puqeue'

Named import 'Puqeue' is not exported; use default import.

Puqeue

✓ const Puqeue = require('puqeue')

CommonJS require pattern works directly.

Creates a queue with concurrency 1 and adds three tasks executed sequentially.

import Puqeue from 'puqeue'; const queue = new Puqeue({ maxOperationCount: 1 }); await Promise.all([ queue.add(async () => { console.log('task1'); }), queue.add(async () => { console.log('task2'); }), queue.add(async () => { console.log('task3'); }) ]); console.log('All tasks completed.');

Debug

Known issues

gotchaIf you pass a non-function to queue.add(), it will throw an error.

fix

Ensure the argument to add() is a function returning a promise.

affects: >=1.0

gotchaDefault priority is 10. Giving priority values less than 10 doesn't guarantee earlier execution order; it's relative only between tasks.

fix

Use distinct priority values to control order.

affects: >=1.0

gotchaSetting maxOperationCount to 0 runs all tasks concurrently without limit, which may cause high memory usage.

fix

Set a finite maxOperationCount for resource control.

affects: >=1.0

Errors

Common errors & fixes

TypeError: queue.add is not a function

Import error: using wrong import statement or mismatched module system.

fix

Use correct import: import Puqeue from 'puqeue' or const Puqeue = require('puqeue').

Uncaught TypeError: add is not a function

Puqeue constructor not properly called (e.g., missing new).

fix

Instantiate with 'new Puqeue()'.
