noqueue

library5.0.15jsnpmunverified

noqueue is an asynchronous queue and loop utility library for Node.js (v5.0.15, last updated in 2021). It provides an infinity loop with built-in queue management, parallel execution, and utility functions like First (race), Fill (allSettled), TillSuccess (retry), and AwaitSleep. Written in TypeScript with ESM support. Differentiates from simple setTimeout/setInterval by offering structured event-driven patterns with failover and synchronous/asynchronous job control. Suitable for task scheduling, retries, and concurrent processing.

Code

Verified usage

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

QueueLoop

✓ import { QueueLoop } from 'noqueue'

✗ import { QueueLoop } from 'noqueue/QueueLoop'

Default export is not available; named import from package root.

ParallelLoop

✓ import { ParallelLoop } from 'noqueue'

✗ const ParallelLoop = require('noqueue').ParallelLoop

Works with CJS require, but ESM import is recommended for TypeScript.

First

✓ import { First } from 'noqueue'

✗ import First from 'noqueue'

First is a named utility function, not default export.

Fill

✓ import { Fill } from 'noqueue'

✗ import { Fill } from 'noqueue/Utilities'

All exports are from the main package, no subpaths.

TillSuccess

✓ import { TillSuccess } from 'noqueue'

Named export; ensures a job retries until success.

Demonstrates basic queue loop usage with AwaitSleep and retry with TillSuccess.

import { QueueLoop, AwaitSleep, TillSuccess } from 'noqueue'; const queue = new QueueLoop(); queue.enqueue(async () => { console.log('Job 1'); await AwaitSleep(100); }); queue.enqueue(async () => { console.log('Job 2'); await AwaitSleep(100); }); // Start processing queue.start(); // Stop after 1 second setTimeout(() => queue.stop(), 1000); // Retry a job till success const fetchData = async () => { const resp = await fetch('https://api.example.com/data', { signal: AbortSignal.timeout(2000) }); if (!resp.ok) throw new Error('Retry'); return resp.json(); }; const result = await TillSuccess(fetchData, { delay: 500, maxRetry: 5 }); console.log('Fetched:', result);

Debug

Known issues

breakingv5 removed CommonJS support? Check documentation; README indicates ESM focus but CJS require works.

fix

Use import syntax or ensure Node version supports ESM; if using CJS, test with require('noqueue').

affects: >=5.0.0

gotchaQueueLoop.start() does not return a promise; jobs are processed asynchronously.

fix

Use events or callbacks to know when queue is empty.

affects: *

gotchaTillSuccess uses exponential backoff? Default delay behavior is not documented; test with custom delay.

fix

Provide explicit delay and maxRetry options to control retry behavior.

affects: *

gotchaFirst utility may leave pending promises if some jobs never resolve; no cancellation support.

fix

Ensure all passed promises settle or use AbortController/timeout.

affects: *

deprecatedAwaitSleep is just a promise-based setTimeout; no special behavior.

fix

Use new Promise(resolve => setTimeout(resolve, ms)) directly if preferred.

affects: *

Errors

Common errors & fixes

Error: Cannot find module 'noqueue'

Package not installed or import path incorrect.

fix

Run `npm install noqueue` and ensure import path is 'noqueue' (not 'noqueue/src').

TypeError: queue.enqueue is not a function

Importing wrong symbol or using default export incorrectly.

fix

Use named import: `import { QueueLoop } from 'noqueue'` and instantiate with `new QueueLoop()`.

SyntaxError: Cannot use import statement outside a module

ESM syntax in a CJS environment or missing 'type':'module' in package.json.

fix

Add 'type':'module' to package.json or use require: `const { QueueLoop } = require('noqueue')`.
