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 🙏

Connect a react component to callbag(s)

Readme

callbag-connect-react

A utility for connecting a React component with Callbag sources. Comparable to ReactRedux, but for Callbags instead of Redux!

npm install callbag-connect-react

usage

import connect from 'callbag-connect-react

@connect(
  { // Objects are assumed to contain sourcess
    propName: source1,
    ...
  },
  [ // Arrays are assumed to contain signals
    [source2, callback],
    ...
  ]
})
class MyComponent extends React {
  ...
}

Now;

  • Whenever source1 emits data, that will be sent to the propName prop in MyComponent.
  • Whenever source2 emits, callback will be invoked with (componentInstance, emission).

Sources

An object where the keys are prop names and values are sources. When a source emits, the corresponding prop will be populated.

Signals

An array of tuples, each tuple is an array with a source and a callback. Whenever the source emits, the callback will be called with the component instance and the emitted data.

Use signals when you want your component to do something other than render when a source emits.
