Optimize Toolset

Iโ€™ve always been into building performant and accessible sites, but lately Iโ€™ve been taking it extremely seriously. So much so that Iโ€™ve been building a tool to help me optimize and monitor the sites that I build to make sure that Iโ€™m making an attempt to offer the best experience to those who visit them. If youโ€™re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, ๐Ÿ‘‹, Iโ€™m Ryan Hefnerย  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 youโ€™re interested in other things Iโ€™m working on, follow me on Twitter or check out the open source projects Iโ€™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 soonโ€“ish.

Open Software & Tools

This site wouldnโ€™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 ๐Ÿ™

๐Ÿ‘‚ React Callbag Listener

NPM Downloads Build Status codecov.io


So you've seen the light and accepted Callbags as the future of reactive front-end development, but you need to update a React component every time a callbag emits a new value?

๐Ÿ‘‚ React Callbag Listener is the answer!


Demo ๐Ÿ‘€

Edit ๐Ÿ‘‚ React Callbag Listener Demo


Installation

npm install --save react-callbag-listener

or

yarn add react-callbag-listener

How it works

You provide any number of callbags as props to ๐Ÿ‘‚ React Callbag Listener, and the render function given as children will be rendered whenever any of them changes.

import CallbagListener from 'react-callbag-listener'

...

// foo$ and bar$ are callbag sources that will emit values
<CallbagListener foo={foo$} bar={bar$}>
  {({ foo, bar }) => (
    <div>
      <div>Foo value is: {foo}</div>
      <div>Bar value is: {bar}</div>
    </div>
  )}
</CallbagListener>

That's it. There are no other options or API to document. The object given to your render prop will have the same keys as you passed as callbag props.
