# obj-observer

js/ts 对象监听

1. 安装依赖

```shell

npm install obj-observer

# 或 npm i

```

2. 在需要的地方引入watch方法，监听对象或数组的变化

```javascript

import {ref,watch} from 'obj-observer'

const obj=ref({test:123})

const dispose=watch(obj,

    (value,oldValue)=>{

        console.log('trigger change',value,oldValue)

    })

obj.test='hi world' //'trigger change' {test:'hello world'} {test:'hi world'} 

```
