# wrong

Another JS object validation module with focus on simplicity.

# API

## buildValidator(rules)

Builds function which promises validation errors for given object.

```js

var validate = buildValidator({

	name: ['required'],

	cash: ['required', 'positive number']

});

var user = {

	name: '',

	cash: -10

};

validate(user).then(function (errors) {

	console.log('User is not valid!', errors);

});

```

## rules

Contains hash of rules: key is name, value is validation function.

Validation function has following signature: `function (value, fieldName, wholeObject)`. It must promise error or return nothing if value is valid. Note: context (`this`) of validate function will be applied to each field validator, so you can use it to pass additional information, like current user.

## arrayValidator(itemValidator)

Constructs array value validator by taking item validator as parameter.

## existanceValidator(finder, [message])

Constructs existance validator (value must be an ID of existing object).
