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 🙏

React Dialog Polyfill

<dialog> element bundled with polyfill for React

Why?

While many other more feature-rich React modal components exists, react-dialog-polyfill aims to be a simple binding of the native <dialog> element for React.

Differences from most of the existing components:

  • Native browser support in browsers like Chrome and Opera
  • Polyfill for un-supported browsers
  • Avoids using React.createPortal, allowing SSR in natively supported browsers
  • Dialog always will display in-front of other elements regardless of z-index
  • Selected info from dialog can be returned via <form> element
  • Well suited for Electron apps

Installation

Yarn

yarn add react-dialog-polyfill

npm

npm install react-dialog-polyfill

Usage

import React, { useState } from 'react'
import { Modal, Dialog } from 'react-dialog-polyfill'

const App = () => {
  const [dialog, setDialog] = useState(true)
  const [modal, setModal] = useState(true)
  return (
    <div>
      <Dialog open={dialog} onClose={(e, dialog) => alert('You closed the dialog')}>
        <div>This is a dialog. Click "Close".</div>
        <button onClick={() => setDialog(false)}>Close</button>
      </Dialog>
      <Modal open={modal}
        onCancel={(e, dialog) => {
          setModal(false)
          alert('You canceled the modal')
        }}
        onClose={(e, dialog) => {
          setModal(false)
          const value = dialog.returnValue
          if (value) alert(`You answered "${dialog.returnValue}" to the modal`)
        }}
      >
        <form method="dialog">
          <div>
            This is a modal.
            Press <pre style={{ display: 'inline-block' }}>Escape</pre> to cancel.
          </div>
          <div>Do you like modals?</div>
          <button type="submit" value="no">No</button>
          <button type="submit" value="yes" autoFocus>Yes</button>
        </form>
      </Modal>
    </div>
  )
}

export default App

Simply add the desired component to the React application using JSX.

The Modal component will block interaction with other elements when it is open, while the Dialog component will not.

Props

Open

open indicates if the modal is open. Default: false

On Close

onClose runs when the modal is explicitly closed. Default: (event, modal) => {}

That is the open prop state is toggled from true to false.

This means that having onCancel={() => setModal(false)} will call onClose from within onCancel.

On Cancel (Modal Only)

onCancel runs when the modal is canceled using Escape. Default: (event, modal) => {}

By default the modal itself will not close as open will still be set however the event will trigger.

It is recommended to set onCancel={() => setModal(false)} to have the modal close when Escape is pressed.
