mini-queue v0.0.14 is a lightweight in-memory job queue for Node.js (engine >=4). It provides a state machine for job lifecycle (new, queue, dequeue, process, complete, reject, cancel) with journaling of state transitions and timestamps. It supports grouping jobs by group and name, and limits journal length. The package is minimal with no external dependencies, suitable for simple queuing needs without persistence or distributed workers. Last updated in 2017-2018, it is in maintenance mode.

Code
Verified usage

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

The library is CommonJS but can be imported with ESM in Node >= 12 using default import transpilation.

import MiniQueue from 'mini-queue';

The module exports a single constructor function as module.exports, not a named export.

const MiniQueue = require('mini-queue');

QueueJob is a property on the exported constructor; it is not exported as a named export in ESM.

const QueueJob = require('mini-queue').QueueJob;

Creates a MiniQueue instance with concurrency 2, creates a job with auto-start, and another manually queued job.

const MiniQueue = require('mini-queue'); const queue = new MiniQueue({ concurrency: 2, maxJournalLength: 10 }); queue.on('error', (err) => console.error(err)); queue.createJob({ group: 'mygroup', name: 'myname', process: (job, done) => { console.log('Processing job', job.id); done(null, 'result'); }, start: true }); // Or manually: const job = queue.createJob({ process: (job, done) => { console.log('Manual job', job.id); setTimeout(() => done(null, 'done'), 100); } }); queue.queueJob(job.id); queue.on('complete', (job) => { console.log('Job completed:', job.id, job.result); console.log('Journal entry:', job.journalEntry); console.log('Full journal:', JSON.stringify(queue.journal, null, 2)); });
