React Composition Api Save

:art: Simple React state management. Made with @vue/reactivity and ❤️.

Project README

Welcome to rxv 👋

Version Documentation License: MIT

Use Vue3 Composition Api in React to manage state, just import @vue/reactivity, rxv means React x Vue

本项目为学习性质,不建议用于生产环境!

🏠 Homepage

Demo

rxv

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 rxv -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。

快速上手示例

store:

import { reactive } from "@vue/reactivity"

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

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

export const store = reactive(state)

export type Store = typeof store

组件:

import React from "react"
import { Provider, useStore } from "rxv"
import { store, add, Store } from "./store"

function Count() {
  const countState = useStore((store: Store) => ({
    count: store.count,
  }))

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

export default () => {
  return (
    <Provider value={store}>
      <div className="flex">
        <Count />
      </div>
    </Provider>
  )
}

相对复杂的示例

这个例子里使用了 Vue3 中的 computedeffect 等能力,是一个相对比较复杂的示例。

// 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 "rxv"
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 复杂示例

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。
