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 🙏

A pan-responder version for the web using react-dom




PanResponder for the web

This module allows to use the PanResponder created for react-native in the web with react-dom.

Not much code in this repo is originally mine:

  • PanResponder is taken directly from facebook source code, making it use just pure JS instead of flow.
  • Responder events are already in react-dom but they are not active, this module injects the ResponderEventPlugin in react's event hub allowing to listen to them.
  • Special considerations for the web and normalization is taken from @necolas's awesome project: react-native-web

I have just glued the pieces.


npm install react-panresponder-web


// Import the pan responder from this package
import PanResponder from 'react-panresponder-web'

// ...then our react component we can initialize it with our own code
this.panResponder =  PanResponder.create({
	onMoveShouldSetResponderCapture: () => true,

	onPanResponderGrant: (e, {x0, y0}) => {	
		this.startDrag( {x: x0, y: y0} )

	onPanResponderMove: (evt, gesture ) => {
		this.onDragging( gesture )

	onPanResponderRelease: () => {

// ...Finally in our render method we can add the listeners
	return (
		<div { ...this.panResponder.panHandlers }>

Just by importing the module the responder events are active for the DOM, they are triggered clicking with the mouse, so you can start listening to them by adding the following props to the elements in your component:

  • onStartShouldSetResponder
  • onMoveShouldSetResponder
  • onResponderGrant
  • onResponderReject
  • onResponderMove
  • onResponderRelease
  • onResponderTerminationRequest
  • onResponderTerminate

Have a look at react-native's gesture responder system to know more.
