# checkmate

[![Build Status](https://travis-ci.org/ArnaudRinquin/checkmate.svg?branch=master)](https://travis-ci.org/ArnaudRinquin/checkmate) [![npm version](https://badge.fury.io/js/checkmate.svg)](https://badge.fury.io/js/checkmate)

Checkmate is a very simple data validator.

*Use cases*

* form input validation

* model validation

*Characteristics*

* no dependency

* framework / lib / context agnostic: describe what you expect → send an object → get errors

* does not come with validation functions, write your own or combine with libraries such as [`is.js`](http://is.js.org/)

*Example*

See the [`react + is_js`](./examples/react-is_js) example.

```js

import checkmate from 'checkmate'

import is from 'is_js'

const checkers = checkmate({

  email: {

    notEmpty: (str) => !is.empty(str),

    isEmail: is.email,

  },

  password: {

    truthy: (str) => !!str,

    minLength: (str) => str && str.length > 7,

  },

})

const errors = checkers({

  email: 'arnaud@efounderscom',

  password: false,

})

console.log(errors)

// → { email: ['isEmail'], password: ['truthy'] }

```
