README
# conuse
> Share `Hook` with `Context`
[English](./README.md) | 简体中文
## 开始
```js
import React, { useState } from 'react';
import createConuse from 'conuse';
// 1️⃣ 创建一个自定义 Hook
const useCounter = () => {
const [count, setCount] = useState(0);
const increment = () => setCount(prevCount => prevCount + 1);
return { count, increment };
};
// 2️⃣ 把自定义 Hook 传入 createConuse 作为参数
const { ConuseProvider, useConuseContext } = createConuse({ counter: useCounter });
function Button() {
// 3️⃣ 使用 use Context 获取自定义 Hook 提供的方法和状态
const { increment } = useConuseContext('counter');
return +;
}
function Count() {
// 4️⃣ 同样，通过 use Context 获取自定义 Hook 提供的方法和状态
const { count } = useConuseContext('counter');
return {count};
}
function App() {
// 5️⃣ 用 Provider 包在你的组件外面
return (
);
}
```
## 安装
npm:
```sh
npm i conuse
```
Yarn:
```sh
yarn add conuse
```
## API
### `const { ConuseProvider, useConuseContext, getContext } = createConuse(useMap[, conuse])`
Conuse 会暴露 `createConuse` 函数，可以通过该函数创建出 `conuse` 类型，类型属性如下：
```
Conuse {
ConuseProvider: React.FC;
useConuseContext: (name?: string) => any;
getContext: (name?: string) => any;
}
```
#### useMap
类型: `{ [name: string]: Hook }`
这是一个自定义 Hook 对象，可以组件多个 Hook。如果你想获取某个 Hook，你可以把 name 传入到 `useConuseContext`，例子如下：
```js
const { useConuseContext } = createConuse({ counter: useCounter });
const Component = () => {
// 拿到 useCounter 值
const { count } = useConuseContext('counter');
return count;
};
```
#### conuse
类型: `Conuse`
可以组件多个 Conuse
```js
const toggleConuse = createConuse({ toggle: useToggle });
const { useConuseContext } = createConuse({ counter: useCounter }, { toggle: toggleConuse });
const Component = () => {
const { count } = useConuseContext('counter');
const { toggle } = useConuseContext('toggle');
return `${count}${toggle}`;
};
```
#### ConuseProvider
类型: `React.FC`
使用方式跟 [Context.Provider](https://reactjs.org/docs/context.html#contextprovider) 一致, 可以把 `ConuseProvider` 放在你 App 组件的最外边。
```js
```
#### useConuseContext
类型: `(name?: string) => any`
获取特定 Hook 的值
```js
const [value, setValue] = useConuseContext()
```
参数 `name` 必须是 `useMap` 里面某个 key，这样子你就可以获取到特定 Hook 值。如果你想要获取所有的 Hook 的话，你可以不传 name。
```js
const { useCounter } = useConuseContext();
const { count } = useCounter();
```
#### getContext
类型: `(name?: string) => any`
你可以通过 getContext 方式，在非 `Function Component` 里面就可以获取到 Hook 值
```js
const handleClick = () => {
const { count } = getContext('counter');
};
const App = () => {
return 点击;
};
```
