fastqueue

library0.1.0jsnpmunverified

A fast FIFO queue for Node.js that uses a two-array cycling strategy to avoid the O(n) reindexing cost of Array.shift() on large queues. Version 0.1.0 is the only release, currently in maintenance mode. Key differentiator: implements only push/shift/unshift/length with minimal overhead, unlike alternatives like denque or double-ended-queue which offer more features.

Verified usage

Queue

✓ const Queue = require('fastqueue')

✗ import Queue from 'fastqueue'

This package only supports CommonJS (require). No ESM or named exports available.

Shows basic FIFO queue operations: push, shift, unshift, and length property.

const Queue = require('fastqueue'); const q = new Queue(); q.push(1); q.push(2); console.log(q.shift()); // 1 console.log(q.shift()); // 2 console.log(q.length); // 0 q.unshift(3); console.log(q.shift()); // 3

Debug

Known issues

gotchaPackage does not expose an ESM interface; using import will fail.

fix

Use require() instead of import.

affects: >=0

gotchaQueue only supports push/shift/unshift and length; no iteration, peek, or clear methods.

fix

Check if these features are needed; consider using denque or double-ended-queue for richer API.

affects: >=0

gotchaThe tiny queue implementation may have subtle bugs with large numbers of elements due to internal array cycling.

fix

Test thoroughly if using with very large queues; consider using a well-maintained alternative.

affects: >=0
