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 🙏

Commit messages

Commit messages should follow the commit message convention so, changelogs could be generated automatically by that. Commit messages are validated automatically upon commit. If you aren't familiar with the commit message convention, you can use yarn commit (or npm run commit) instead of git commit, which provides an interactive CLI for generating proper commit messages.

Known Issues

Alpha is not working: Safari / iOS

When using rgba as a primaryColor or secondaryColor value, Safari does not respect the alpha channel, meaning that the color will be opaque. To prevent this, instead of using an rgba value for primaryColor/secondaryColor, use the rgb equivalent and move the alpha channel value to the primaryOpacity/secondaryOpacity props.

{/* Opaque color in Safari and iOS */}
<ContentLoader
  primaryColor="rgba(0,0,0,0.06)"
  secondaryColor="rgba(0,0,0,0.12)">
{/_ Semi-transparent color in Safari and iOS _/}
<ContentLoader
    primaryColor="rgb(0,0,0)"
    secondaryColor="rgb(0,0,0)"
    primaryOpacity={0.06}
    secondaryOpacity={0.12}>
Black box in Safari / iOS (again)

Using base tag on a page that contains SVG elements fails to render and it looks like a black box. Just remove the base-href tag from the <head /> and issue solved.
