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 🙏

Use Vue3 Composition Api in React, just import @vue/reactivity

🏠 Homepage

Demo

react-composition-api

在React应用中使用@vue/reactivity中的所有响应式能力

  1. 使用setup在组件中体验Vue-Composition-Api
  2. 使用极简的api实现全局状态管理

Docs

https://sl1673495.github.io/react-composition-api

Why

  1. 直接引入@vue/reacivity,完全使用Vue3的reactivity能力,拥有computed, effect等各种能力,并且对于SetMap也提供了响应式的能力。 后续也会随着这个库的更新变得更加完善的和强大。
  2. vue-next仓库内部完整的测试用例。
  3. 完善的TypeScript类型支持。
  4. 完全复用@vue/reacivity实现超强的全局状态管理能力
  5. 状态管理中组件级别的精确更新。

Usage

npm i react-vue-reactivity -S
npm i @vue/reactivity -S

支持@vue/reactivity内部提供的所有api,并在React组件中使用。

最简单的demo如下:

全局状态管理

// store.ts
import { reactive, computed, effect } from '@vue/reactivity';

export const state = reactive({
  count: 0,
});

const plusOne = computed(() => state.count + 1);

effect(() => {
  console.log('plusOne changed: ', plusOne);
});

const add = () => (state.count += 1);

export const mutations = {
  // mutation
  add,
};

export const store = {
  state,
  computed: {
    plusOne,
  },
};

export type Store = typeof store;
// Index.tsx
import { Provider, useStore } from 'react-vue-reactivity'
function Count() {
  const countState = useStore((store: Store) => {
    const { state, computed } = store;
    const { count } = state;
    const { plusOne } = computed;

    return {
      count,
      plusOne,
    };
  });

  return (
    <Card hoverable style={{ marginBottom: 24 }}>
      <h1>计数器</h1>
      <div className="chunk">
        <div className="chunk">store中的count现在是 {countState.count}</div>
        <div className="chunk">computed值中的plusOne现在是 {countState.plusOne.value}</div>
         <Button onClick={mutations.add}>add</Button>
      </div>
    </Card>
  );
}

export default () => {
  return (
    <Provider value={store}>
       <Count />
    </Provider>
  );
};

可以看出来,store的定义完全复用了@vue/reactivity中的能力,而不会引入额外的学习成本,并且里面的所有能力都可以完美支持。

具体的代码和效果可以看文档中的全局状态管理

组件内部使用setup

import { setup } from 'react-vue-reactivity';
import { reactive } from '@vue/reactivity'

export default setup(() => {
  const data = reactive({ message: 'World' });

  const change = () => (data.message = 'Hey');

  return props => (
    <>
      <span>Hello {data.message}</span>
      <button onClick={change}>change</button>
    </>
  );
});

组件使用setup的方式和Vue-Composition-Api保持了一致,setup返回的是一个React.FC函数,

外层只需要在初始化的时候执行一次,而返回的FC则需要每次渲染的时候都重新执行。

支持的Vue3 api

除了内置的几个api以外,其他所有的api都是Vue内部提供的。

具体支持的api,可以看vue-next仓库中的导出的api

export { ref, isRef, toRefs, Ref, UnwrapRef } from './ref'
export {
  reactive,
  isReactive,
  readonly,
  isReadonly,
  shallowReadonly,
  toRaw,
  markReadonly,
  markNonReactive
} from './reactive'
export {
  computed,
  ComputedRef,
  WritableComputedRef,
  WritableComputedOptions,
  ComputedGetter,
  ComputedSetter
} from './computed'
export {
  effect,
  stop,
  pauseTracking,
  resumeTracking,
  ITERATE_KEY,
  ReactiveEffect,
  ReactiveEffectOptions,
  DebuggerEvent
} from './effect'
export { lock, unlock } from './lock'
export { TrackOpTypes, TriggerOpTypes } from './operations'

注意computedref这些包装后的值没有提供自动拆包的功能,必须用data.value去读取和赋值。
