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 🙏

安装

# 安装库
yarn add @ccreator/mirror

使用

1. 定义模型

说明:模型装载时,会自动添加set、reset和get方法,请不要给模型增加这些方法,否则会被覆盖

// src/models/demo.js
import { actions } from '@ccreator/mirror';

export default {
    // 模型名称
    name: 'demo',
    // 模型的状态
    state: { books: [] },
    // 同步的方法
    reducers: {
        // 调用方式:actions.demo.addBook({ name: '孙子兵法', author: '孙武' });
        addBook(state, payload) {
            const { books } = state;
            books.push(payload);
            return { ...state, books: [...books] };
        }
    },
    // 异步的方法
    effects: {
        // 调用方式:actions.demo.fetchList({ author: '孙武' });
        async fetchList(payload, getState) {
            // getState()获取所有全部状态数据
            // console.log(getState());
            const resp = await fetch(`/books?author=${payload.author}`);
            const books = await resp.json();
            actions.demo.set({ books });
        }
    },
}

2. 初始化状态存储(Store)

// store.js
import mirror from '@ccreator/mirror';
import app from './models/app';
import demo from './models/demo';

// 1.加载模型
mirror.model(app);
mirror.model(demo);
// 尽量拆分模型到独立文件
mirror.model({
    name: 'loading',
    state: 0,
    reducers: {... ...}
});

// 2.创建数据存储
const store = mirror.createStore();

export defalut store;

3. 注入状态存储(Store)

// index.js
import React from 'react'
import ReactDOM from 'react-dom/client'
import mirror, { Provider } from '@ccreator/mirror';
import App from './App'
import store from './store';

// Action执行的回调钩子
mirror.hook(console.log)

ReactDOM.createRoot(document.getElementById('root')).render(
    <React.StrictMode>
        <Provider store={store}>
            <App />
        </Provider>
    </React.StrictMode>,
)

4. 子组件连接状态存储

const App = ({ author, price, xxx }) => {
    ... ...
}

function dispatch({ book, xxx }) {
    return {
        author: book.author,
        price: book.price,
        xxx,
    };
}

export default connect(dispatch)(App);

动态加载模型

  1. 注意事项:需要先加载,然后才能调用模型指令,否则actions.{model}.{action}空值异常
  2. 注意事项:如果使用React.lazy加载组件,推荐使用方案1实现业务模块的拆分
  3. 注意事项:注意保持模型名称唯一,防止模型属性和指令方法被覆盖
import React from 'react';
import mirror, { actions, connect } from '@ccreator/mirror';
import model from './user';
import get from 'lodash/get';

// 方案1:配合React.lazy实现动态加载
mirror.model(model);

const Main = ({ page, dataSource }) => {

    React.useEffect(() => {
        // 方案2:组件内实现动态加载
        // mirror.model(model);
        const temp = actions.user.get('page');
        console.log(temp);
        actions.user.set({ page: { index: 100, size: 1024 } });
    }, []);

    return <>{JSON.stringify({ page, dataSource })}</>;
};

function dispatch({ user }) {
    // 注意user模型未加载时,user为undefined,可以使用lodash.get防止空值异常
    return {
        page: {
            index: get(user, 'page.index', 1),
            size: get(user, 'page.size', 10)
        },
        dataSource: user?.dataSource,
    };
}

export default connect(dispatch)(Main);

更新内容
