## em2
this is a front end easy model manager
### Usage
#### create model
```
import em2 from 'em2';
const User = new em2({
url: [api],
fields: [model fields, for cleaning params under POST, PUT, OPTIONS... methods]
}, {
pkey: [id => primary key, default is '_id'],
parseData: [function => global parseData handler, when data fetched, just after data to json object],
exception: [function => global error handler],
})
```
fields can used three way:
```
fields: {
name: {
type: String,
default: '',
},
age: {
type: Number,
default: 0,
}
...
}
```
```
fields: [
{
name,
type: String,
default: '',
},
{
name: 'age',
type: Number,
default: 0
}
...
]
```
or simple way:
```
fields: ['name', 'age', ...]
```
then use it:
#### model methods
```
//GET api?name=a&sex=b
User.find({name: 'a', sex: 'b'}).then(data => {
// after parseData if have parseData
}).catch(error => {
// after exception if have
})
```
```
//GET api/:_id?name=a&sex=b
User.findOne(_id, params).then(succFunc).catch(errFunc)
```
```
//POST api body: params
User.create(params)...
```
```
//PUT api/:_id body:params
User.update({_id, name: 's', ...})
```
```
//POST or PUT, whether params has model's pkey
User.save(params)
```
```
//DELETE api?name=a&sex=b
User.destroy({_id, name: 'a',...})
```
#### nested model
```
const Comment = new em2({
url: '/post/:post_id/comment'
})
// GET /post/[post_id]/comment
Comment.find({post_id, ...})
// GET /post/[post_id]/comment/[_id]
Comment.findOne({post_id, _id})
```
#### also has default request
```
// request
User.request(['get', 'post', ...], api, params).then(data => {
// after parseData
}).catch(error => {
// after exception
})
```
warning:
if you need model's `this`(like this.pkey, or this.fields), function **parseData** should not be write in arrow function. neither do function **exception**
