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 🙏

Readme

Rectx

React + Context -> Rectx, 轻量级状态管理库。

安装

npm install --save rectx

简单使用

import React from 'react'
import ReactDOM from 'react-dom'
import { Provider, Controller, Listen } from 'rectx'

class LikeController extends Controller {
    state = {
        isLike: false,
        isMount: false
    }

    handleClick = () => {
        this.setState({
            isLike: !this.state.isLike
        })
    }
}

const Like = () => (
    <Listen
        to={[LikeController]}
        didMount={like => {
            like.setState({ isMount: true })
        }}
    >
        {like => (
            <div>
                <button onClick={() => like.handleClick()}>Click me</button>
                <div>{like.state.isMount ? 'component being loaded' : 'component not loaded'}</div>
                <div>{like.state.isLike ? 'I love you' : 'I hate you'}</div>
            </div>
        )}
    </Listen>
)

ReactDOM.render(
    <Provider>
        <Like />
    </Provider>,
    document.getElementById('root')
)

现在我们已经完成了一个非常简单的例子。在这个例子中,我们定义了一个 LikeMachine 状态机,用于保存 Like 组件所需要的一切状态。

意义何在?

让我们认真的观察一下这段简单的代码,很快你就能发现其中的奥妙:

class LikeMachine extends Machine {
    state = {
        isLike: false
    }

    handleClick = () => {
        this.setState({
            isLike: !this.state.isLike
        })
    }
}

const Like = () => (
    <Listen to={[LikeMachine]}>
        {like => (
            <div>
                <button onClick={() => like.handleClick()} />
                <div>{like.state.isLike ? 'I love you' : 'I hate you'}</div>
            </div>
        )}
    </Listen>
)

发现了吗?只要使用 <Listen to={[LikeMachine]}/> 对组件进行包裹,那么这个组件就拥有了监听状态变化的能力。没错,这其实还是 PUB/SUB 模式的一种,但是相对于 Redux 我们更好理解。因为,我们依旧在使用 setState API
