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 🙏

Demo

Usage

Import poke-js by including the following script tag in your HTML:

<script src="https://unpkg.com/poke-js"></script>

The global variable Poke is now available with the init & watch methods. Use these to initialize your data object and add 'watcher' functions to be run whenever any of their data dependencies are updated.

const { init, watch } = Poke

let data = { price: 5, quantity: 2 }
init(data)

// total output
const totalOutput = document.getElementById('totalOutput')
watch(() => totalOutput.innerText = data.price * data.quantity)

In this example, any changes to the price or quantity properties of data, will update the DOM element with the id totalOutput.

The properties of the data passed to Poke.init() are also easily bound to the value & innerText of DOM elements by using the data-bind attribute.

Price: <span data-bind="price"></span>

Furthermore, poke-js will listen to input events on any element with the data-input attribute and reflect the change in the corresponding data value.

<input data-input="quantity" type="number" />

To see an example of all of this working together, check out this CodeSandbox.
