# waterline-criteria

Utilities for working with Waterline criterias, especially for applying them to in-memory datasets.

> This module was designed for adapters which communicate with key/value stores such as [`sails-disk`](https://github.com/balderdashy/sails-disk), [sails-memory](https://github.com/balderdashy/sails-memory), and [sails-redis](https://github.com/balderdashy/sails-redis) (i.e. they already implement the `semantic` interface, but need to implement the `queryable` interface).


## Installation

```sh
$ npm install waterline-criteria --save
```

## Usage

```js
var wlFilter = require('waterline-criteria');

var SOME_DATASET = [
  {
    id: 1,
    name: 'Lyra'
  },
  {
    id: 2,
    name 'larry'
  }
];

var results = wlFilter(SOME_DATASET, {
  where: {
    name: { contains: 'lyr' }
  }
}).results;

// x ==> [{name: 'Lyra', id: 1}]
```
