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.


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 🙏

topbar progress indicator React component





Build Status Version

topbar progress indicator as a React component

Will simply show() and hide() topbar when the component is respectively mounted and unmounted.

Since topbar is a singleton, using <TopBarProgress /> multiples times will take this in consideration. This means that hide() will only be called when all <TopBarProgress /> have been unmounted.

For example, if you render 2 <TopBarProgress /> and unmount one (eg: you are doing 2 async things and only once is done), hide() won't be called. You will need to have both instances unmounted.


npm install react-topbar-progress-indicator
## or
yarn add react-topbar-progress-indicator


import TopBarProgress from "react-topbar-progress-indicator";

  barColors: {
    "0": "#fff",
    "1.0": "#fff"
  shadowBlur: 5

const YourThing = () => {
  return <div>{this.state.loading && <TopBarProgress />}</div>;


Since topbar is a singleton, you should configure via Topbar.config().

barThickness (Integer, px)

The progress bar thickness in px (default: 3).

barColors (Object { progress: color })

Object of gradient color stops used to draw the progress bar.


  barColors: {
    "0": "#f00",
    "0.5": "#0f0",
    "1.0": "#00f",


Integer of the shadow blur in px (default: 10).


String that represent the shadow color (hexa, default: #000).
