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-simplifier/babel-plugin

A Babel plugin that makes writing React components concise and fast.

:warning: WARNING: This project is still in early develop stage! DO NOT use it on production! :warning:

How it works?

Let's have a look on an example. This is a simple React component:

const Counter = () => {
  const [counter, setCounter] = useState(0);

  const increment = () => {
    setCounter((prevValue) => prevValue + 1);
  };

  return (
    <div>
      <span>{counter}</span>
      <button onClick={increment}>Increment</button>
    </div>
  )
};

And here, the same component but with React Simplifier:

const Counter = () => {
  const $counter = 0;

  const increment = () => { counter++; }

  return (
    <div>
      <span>{counter}</span>
      <button onClick={increment}>Increment</button>
    </div>
  )
};

As you can see, working with this plugin is much easier, because you don't have to import useState and use the useState getter/setter. You can deal with the component's state as with normal JS variables. Under the hood the React useState hook is still used so the compiled code will look like this:

import { useState } from 'react';

const Counter = () => {
  const [$counter, ____set$counter] = useState(0);

  const increment = () => ____set$counter((prevValue) => prevValue + 1);

  return (
    <div>
      <span>{counter}</span>
      <button onClick={increment}>Increment</button>
    </div>
  )
};

But you don't need to care, because the plugin does it for you. :wink:

Installation

The plugin is available as an npm package.

npm i @react-simplifier/babel-plugin

After installation you have to add the plugin to your Babel config file.

module.exports = {
  ...
  plugins: [
    '@react-simplifier/babel-plugin'
  ]
}

Configuration

| Property | Required | Type | Default value | Description | | -------- | -------- | ---- | ------------- | ----------- | | stateVariablePattern | :x: | RegExp | /^\$\w+/ | Set pattern to recognize React state variables. The default pattern starts with the dollar sign - $foo |

FAQ

Does the plugin work with class components?

Not yet, we plan to add support for class components in the future - this is one of our priorities.
