react-neat v1.0.12
React Neat
react-neat 是一个 React Hooks 工具库,同时它也是一个轻量级的状态管理库。
安装
你可以选择使用 npm 或者 yarn 安装
- 使用 npm:
npm install react-neat
- 使用 yarn:
yarn add react-neat
快速入门
只需简单的几步就可以获得一个功能完善的状态管理库,跟这下面的步骤开始吧。
tips:目前暂支持 hook 写法,因此需要使用>=16.8.0 的 React
在项目根组件中注入状态库:
// index.tsx import React from 'react'; import App from './App'; import { Provider, getStore, useStore } from 'react-neat'; // 引入 const sleep = async t => new Promise(resolve => setTimeout(resolve, t)); // actions用来操作状态库中的state,同是它支持异步操作。 const actions = { // 同步action increment(state) { return { count: state.count + 1 }; }, // 异步action async decrement(state) { await sleep(2000); return { count: state.count - 1 }; }, // 传参 setName(state, value) { return {name: value } } }; export default function Index() { const userStore = getStore('user', actions); // 创建user store const storeReducer = useStore(userStore, { count: 0, name: 'my name' }); // 获取StoreReducer,它是操作store的核心 // 通过Provider组件将storeReducer注入到根组件中,同时你还需要将userStore注入进去。 return ( <Provider value={storeReducer} store={userStore}> <App></App> </Provider> ); }
消费 store:
// App.tsx import React from "react"; import { getStore, useStoreContext } from "react-neat"; // 引入 export default function App() { const { state, actions } = useStoreContext<any, any>(getStore("user")); // 获取userStore的StoreReducer,它提供了state以及actions用户获取以及操作状态。 return ( <section> <h2>login page</h2> <p> count: {state.count}, name: {state.name} </p> <button onClick={() => actions.increment()}>increment</button> <button onClick={() => actions.decrement()}>decrement</button> <button onClick={() => actions.setName('Bob')}>set name</button> </section> ); }

进阶指南
通常我们可能需要创建多个store
,为此提供了Providers
组件可以方便的同时注入多个store
。
在项目根组件中注入状态库:
// index.tsx import React from 'react'; import ReactDOM from "react-dom"; import App from './App'; import { Providers, getStore, useStore } from 'react-neat'; // 引入 import userActions, { userInitState } from './actions/userActions' import bookActions, { bookInitState } from './actions/bookActions' export default function Index() { // 创建user store const userStore = getStore('user', userActions); // 创建book store const bookStore = getStore('book', bookActions); // 获取StoreReducer,它是操作store的核心 const userStoreReducer = useStore(userStore, userInitState); const bookStoreReducer = useStore(bookStore, bookInitState);
// 通过Providers组件将storeReducer注入到根组件中,同时你还需要将userStore注入。
// 与Provider组件不同的是,Providers可以同时注入多个store。
return (
<Providers values={[userStoreReducer, bookStoreReducer]} stores={[userStore,bookStore]}>
<App></App>
</Providers>
);
}
ReactDOM.render(, document.getElementById('root'));
```tsx
// actions/userActions
const sleep = async t => new Promise(resolve => setTimeout(resolve, t));
// actions用来操作状态库中的state,同是它支持异步操作。
const userActions = {
// 同步action
increment(state) {
return { count: state.count + 1 };
},
// 异步action
async decrement(state) {
let count = 0;
await sleep(2000);
return { count: state.count - 1 };
},
// 传参
setName(state, value) {
return {name: value }
}
};
export default userActions
// 状态初始化
export const userInitState = { count: 0, name: 'Toney' }
// actions/bookActions
// actions用来操作状态库中的state,同是它支持异步操作。
const bookActions = {
setName(state, value) {
return { name: value }
},
setAuthor(state, value) {
return { author: value }
}
};
export default bookActions
// 状态初始化
export const bookInitState = { name: 'Natural', author: 'Toney' }
消费 store:
// App.tsx import React from "react"; import { getStore, useStoreContext } from "react-neat"; // 引入 export default function App() { // 获取userStore的StoreReducer,它提供了state以及actions用户获取以及操作状态。 const userStore = useStoreContext<any, any>(getStore("user")); const bookStore = useStoreContext<any, any>(getStore("book")); return ( <section> <h2>App page</h2> <h3>people</h3> <p> count: {userStore.state.count}, name: {userStore.state.name} </p> <button onClick={() => userStore.actions.increment()}>increment</button> <button onClick={() => userStore.actions.decrement()}>decrement</button> <button onClick={() => userStore.actions.setName('Bob')}>set name</button> <h3>book</h3> <p> name: {bookStore.state.name}, author: {bookStore.state.author} </p> <button onClick={() => bookStore.actions.setName('Brief History of Time: from the Big Bang to Black Holes')}>set name</button> <button onClick={() => bookStore.actions.setAuthor('Stephen William Hawking')}>decrement</button> </section> ); }
