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 🙏

React component that makes it easy to compose hashchange and hash click handling into your application or site.

React component that makes it easy to compose hashchange and hash click handling into your application or site.


Install via npm

npm install --save react-hash-handler

Install via Yarn

yarn add react-hash-handler

How to use

At its core, the HashHandler is a pretty straight-forward component that doesn’t do much beyond letting your site or app know when the hash changes, or when a hash link is clicked. Feel free to use it however you want via the callback props that are available on the component.


  • onChange:Func - Called when the browser hashchange event is fired.

  • onClick:Func - Called when a hash link (ex. <a href="#contact">Contact</a>) is clicked.


import React, { Component } from 'react';
import TargetScroller from 'react-target-scroller';
import HashHandler from 'react-hash-handler';

class ExampleComponent extends Compnonent {
  constructor(props) {

    this.state = {
      scrollTarget: null,

    this.onHashChange = this.onHashChange.bind(this);
    this.onHashClick = this.onHashClick.bind(this);

  onHashChange({hash}) {
      scrollTarget: `#${hash}`,

  onHashClick({hash}) {
      scrollTarget: `#${hash}`,

  render() {
    const {
    } = this.state;

    return (
      <div className="page-wrapper">
        <TargetScroller target={scrollTarget} />
            <li><a href="#overview">Overview</a></li>
            <li><a href="#about">About</a></li>
            <li><a href="#contact">Contact</a></li>
        <section id="overview">
        <section id="about">
        <section id="contact">
