[](LICENSE)
[](https://www.npmjs.org/package/coa-helper)

[](https://github.com/coajs/coa-helper/pulls)COA 基础工具库,包含常用方法、必要的第三方类库
## 使用说明
### 安装
```shell
yarn add coa-helper
```### 导入
```typescript
// 导入 helper
import { helper } from 'coa-helper'// 也可以导入为短字符 $
import { $ } from 'coa-helper'// $ 是 helper 的别名,两者完全相同的,都可以正常使用,下文均以 $ 为例
$ === helper // true
```### 常用方法
```typescript
// 异步休眠,代码暂停指定毫秒(注意:必须在async函数下运行,前面要加await)
await $.timeout(1000)// 解析成数组,如果已经是数组则直接返回,不是数组则将值放在数组中,如果为空则返回空数组
$.parseArray([1, 2, 3]) // [1, 2, 3]
$.parseArray(1) // [1]
$.parseArray('A') // ['A']
$.parseArray(undefined) // []
$.parseArray(null) // []// 将对象数组转成键值对的对象形式
const list1 = [
{ id: 'a', name: 'A' },
{ id: 'b', name: 'B' },
{ id: 'c', name: 'C' },
]
$.list2object(list1, 'id') // { a: { id: 'a', name: 'AA' }, b: { id: 'b', name: 'BB' },c: { id: 'c', name: 'BB' }}// 将所有键转换为snakeCase风格
const object1 = { userId: '1', userName: 'A', extendData: { userAge: 25, userAvatar: '' } }
const object2 = $.snakeCaseKeys(object1) // { user_id: '1', user_name: 'A', extend_data: { user_age: 25, user_avatar: '' }}// 将所有键转换为camelCase风格
$.camelCaseKeys(object2) // { userId: '1', userName: 'A', extendData: { userAge: 25, userAvatar: '' } }
