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-zap-state

Simple react utility to improve local-state experience

Install

npm install --save react-zap-state

or

yarn add react-zap-state

Features

  • react-zap-state uses state updation approach from class based component.
  • It memoization to the component by default.
  • It keeps the state outside the component so the code looks more neat and easy to read.
  • For older version (< v18) of react react-zap-state provides batched state updates.

Why

react-zap-state if trying to help with some of the issues with react functional component -

  • Most of the react component need memoization.
  • A lot of components have multiple states, which makes it hard to manage them and code becomes hard to read and understand.
  • Sometimes there are things which needs to be done only after the state is updated, currently useEffect is used to watch the changes in state (developer also need to make sure to handle the intital state in useEffect, which creates more boilerplate code).

Exmples

Basic

Javascript

import { zap } from  "react-zap-state";

const appState = {
    count: 1
};

function App({state}) {
    const updateCount = () => {
        state.set({count: state.count+1}, () => {
            console.log("state updated");
        });
    };

    return (
        <button onClick={updateCount}> count: {state.count} </button>
    );
};

export default zap(App, appState);

Typescript

import { zap, ZapProps } from  "react-zap-state";

const appState = {
    count: 1
};
type AppProps = ZapProps<typeof appState> & {
    // add props here
}
function App({state}: AppProps) {
    const updateCount = () => {
        state.set({count: state.count+1}, () => {
            console.log("state updated");
        });
    };

    return (
        <button onClick={updateCount}> count: {state.count} </button>
    );
};

export default zap<AppProps>(App, appState);

Derive state from props

    export default zap(Component, (props) => {
        // return state
        return {
            ...
        }
    });
