## README

# loopback-extra-filters
This package is designed to provide filter alternatives under the loopback query data.

The extra filters do not change queries generated by [loopback-datasource-juggler](https://github.com/strongloop/loopback-datasource-juggler), but are applied to the resulting object.

### Install

```javascript
// server/boot/extra-filters.js
'use strict';

const Boot = require('loopback-extra-filters/lib/boot');

module.exports = function(server) {
  Boot.apply(server);
};
```

### Filters

- has - Check if you have the property.
- notHas - Check if you do not have the property.
- isEmpty -Check if array property is empty
- isNotEmpty - Check if array property is not empty.

### Examples

- Filter:

```javascript
// Product has category (Ex.: relation belongsTo)
{
  "include": {
    "relation": "category",
  },
  "isHas": "category" //or ["category", ...]
}

// Product has no category (Ex.: relation belongsTo)
{
  "include": {
    "relation": "category",
  },
  "isHas": "category" //or ["category", ...]
}

// Product without items (Ex.: relation hasMany)
{
  "include": {
    "relation": "items",
  },
  "isEmpty": "items" //or ["items", ...]
}

// Product with items (Ex.: relation hasMany)
{
  "include": {
    "relation": "items",
  },
  "isNotEmpty": "items" //or ["items", ...]
}
```
