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 🙏

Prime Check

Small and efficient NPM package for checking if a number is prime. Existing packages seemed to not cache or in the case they did would build up the primes via the Sieve of Erathosthenes. This package will tell you if a number is prime, but not allow discovery of next/previous primes. The first 1000 are hard-coded as I am under the impression those will be the most frequently looked for.

Usage

const isPrime = require('prime-check')
isPrime(1) // false
isPrime(3) // true

Getting Started

To run this module install it into your project by running: npm i --save prime-check

Prerequisites

Ensure node is above version 6.4 as the package contains ES2015 Syntax

Running the tests

To work on this further you can watch-files and run tests after changes are made with the command: npm run dev
