AutoStore

官网

Very easy and elegant state management library. It is based on proxy and provides functions such as signaling, computation, and watching to ensure fine-grained updates

特性

响应式核心：基于Proxy实现，数据变化自动触发视图更新
就地计算属性：独有的就地计算特性，可以在状态树中任意位置声明computed属性，计算结果原地写入。
依赖自动追踪：自动追踪computed属性的依赖，只有依赖变化时才会重新计算
异步计算：强大的异步计算控制能力，支持超时、重试、取消、倒计时、进度等高级功能。
状态变更监听：能监听get/set/delete/insert/update等状态对象和数组的操作监听。
信号组件：支持signal信号机制，可以实现细粒度的组件更新。
调试与诊断：支持chrome的Redux DevTools Extension调试工具，方便调试状态变化。
嵌套状态：支持任意深度的嵌套状态，无需担心状态管理的复杂性
表单绑定：强大而简洁的双向表单绑定，数据收集简单快速
循环依赖：能帮助检测循环依赖减少故障
Typescript: 完全支持Typescript，提供完整的类型推断和提示
单元测试：提供完整的单元测试覆盖率，保证代码质量

安装

npm install @autostorejs/react
yarn add @autostorejs/react
pnpm add @autostorejs/react

快速入门

基本用法

import { createStore } from '@autostorejs/react';

const { $, state,useState } = createStore({
  user: {
    firstName: 'zhang',
    lastName: 'fisher',
    fullName: (scope)=> { 
      return scope.firstName + scope.lastName;
    }
  }
});

// use in component
const Card = () => {
    const [ firstName,setFirstName ] = useState('user.firstName');
    const [ lastName,setLastName ] = useState('user.lastName');
    return <div>
      <div>FirstName:{firstName}</div>
      <div>LastName:{lastName}</div>
    </div>
}

信号组件

import { createStore } from '@autostorejs/react';

const { $, state } = createStore({
  user: {
    firstName: 'zhang',
    lastName: 'fisher',
    fullName: (scope)=> { 
      return scope.firstName + scope.lastName;
    }
  }
});

// signal component, only update when user.firstName or user.lastName change
const Card = () => { 
    return <div>$('user.fullName')</div>
}

原地计算

import { createStore,computed } from '@autostorejs/react';

const { $, state } = createStore({
  user: {
    firstName: 'zhang',
    lastName: 'fisher',
    fullName: computed(async (scope)=> { 
      return scope.firstName + scope.lastName;
    },["./firstName","./lastName"])
  }
});

// signal component, only update when user.firstName or user.lastName change
const Card = () => { 
    return <div>$('user.fullName')</div>
}

async computed with loading,timeout, retry, cancel, countdown, progress.

表单双向绑定

Form two-way binding is very simple.

import { createStore,computed } from '@autostorejs/react';

const { $, state,useForm } = createStore({
  user: {
    firstName: 'zhang',
    lastName: 'fisher',
  }
});

// simple two-way form binding
const Card = () => { 
    const user = useForm()
    return <div {...user}>
      <input name="user.firstName" />
      <input name="user.lastName" />
    </div>
}
