## README

# Mongoing

适合用于云函数的`mongodb`中间件

- 连接数据库，提取`collection`
- 函数逻辑结束自动关闭数据库连接

## 使用方法

搭配`aliyun-function-compat`或`fcapi`使用

数据库连接地址从`mongoing`第二个参数获取，如果未指定这个参数，则从环境变量`MONGODB`获取，

如果环境变量未指定，则使用`mongodb://127.0.0.1:27017/mongoing`

连接成功后，会自动获取所有`collection`并转换成对象表附加到最后一个参数

如果需要使用未使用过的集合，并且连接地址不通过第二个参数设置，可以在第二个参数指定`collection`数组

或者在第三个参数指定

可以通过访问`__client`和`__db`获取客户端连接对象和DB对象

```javascript
const mongoing = require('mongoing')
const fcapi = require('fcapi')

exports.handler = fcapi(mongoing(async (event, context, {__client, __db, users}) => {
    // 客户端连接
    __client

    // db
    __db

    // collection
    users
}))

// 指定连接地址
mongoing(callback, url)

// 指定collection
mongoing(callback, ['users', 'posts'])

// 指定连接地址和数组
mongoing(callback, url, ['users'])
```
