Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Foxkit Sort

This package contains variations of the Quick Sort and Selection Sort algorithms as functions that take a sortBy argument similar to the callback paramter of Array.prototype.sort.

Installation

yarn add -D @foxkit/sort

Usage

import { qSort } from "@foxkit/sort";

// sort by a <= b
qSort(myArr);

// sort by a.id <= b.id
qSort(myObjs, "id");

// sort using custom callback
qSort(myObjs, (a, b) => b.id - a.id); // descending order

The following algorithms are available:

  • qSort: Quick Sort
  • qSortDP: Dual-pivot Quick Sort
  • selSort: Selection Sort

Note: Due to the nature of these algorithms duplicates may appear in random order. You can prevent this with a custom callback function if you have other properties available for comparison.

Callback Function

The callback function may return any number (such as the result of a subtraction) or boolean (return true if a should come before b)

selSort(myObjs, (a, b) => a.id > b.id); // descending order

Stable Quick Sort

Stable variants of qSort and qSortDP are available in the /stable import. These are generally slower by a tiny amount but take the position in the original array into consideration, leading to deterministic results:

import { qSort } from "@foxkit/sort/stable";

const myArr = [
  { v: 3, idx: 0 },
  { v: 1, idx: 1 },
  { v: 7, idx: 2 },
  { v: 3, idx: 3 }
];

qSort(myArr, "v"); /* results in:
[
  { v: 1, idx: 1 },
  { v: 3, idx: 0 },
  { v: 3, idx: 3 },
  { v: 7, idx: 2 }
] */
