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 🙏

hex-string

Fast hex / binary transcoding in pure JavaScript.

Why

Not as fast as node's implementation, but quite a bit faster than using toString(16) and parseInt(n, 16) which is generally what's used in the browser.

On a chromebook, using [email protected]:

$ npm run bench

> [email protected] bench hex-transcoder
> node bench

65536 trials, 16384 bytes per trial
encode (node Buffer): 5.644s
decode (node Buffer): 9.227s
encode (toString): 13.067ms
decode (parseInt): 26.282ms
encode (this module): 14.23ms
decode (this module): 23.725ms

How

Do maths in plain JavaScript.

Test

$ npm run test

Notes

  • Tested against node's Buffer for compatibility
  • Decode returns Uint8Array instead of Buffer
