Use

To use a validator simply include the angular directive in an input element.

<form name="form">
  <input type="text" ng-model="value" name="value" is-mongo-id />
</form>

You can use multiple directives at once

<form name="form">
  <input type="text" ng-model="value" name="value" is-alpha is-lowercase />
</form>

Async Validation

As of version 3.41.3 angular validators support async validation. To use async validation first you have to configure the asyncValidatorProvider in your app.js

angular.module('my-project', [
    ...,
    'angular.validators'
])
.config(['asyncValidatorProvier', function(asyncValidatorProvider){
    asyncValidatorProvider
        .baseUrl('http://localhost:1337')
        .endpoint('usernane', '/api/username/{value}')
        ...
}])

Some words on the api: the api must return a JSON object that has an attribute named data and within an other attribute that contains the result. The default name for the attribute is 'valid'. You can change the name of the attribute on the config phase using the 'responseField' function.

The available options for asyncValidatorProvider are the following:

function	arguments	description	example
baseUrl(string)	string	sets the base url for api (helper function)	.baseUrl('http://localhost:1337')
defaultState(boolean)	boolean	the default state of the validator (defaults to false).	.defaultState(true)
endpoint(name, url)	name: string, url: string	sets an endpoint with an easy to use name	.endpoint('username', '/api/account/{value}
httpVerb(verb)	verb:string	Sets the http verd that the api accepts for async validation, defaults to get	.httpVerb('post')
invalidResponse(response)	response: string	the response the api returns if the value is invalid, defaults to 'false'	.invalidResponse('false')
minLength(length)	length: int	the min length that the view value neeeds to have in order to make a call to the api, defaults to 3	.minLength(4)
responseField(field)	field: string	change the name of the field that contains the respone	.responseField('valid')
validResponse(response)	response: string	the response the api returns if the value is valid, defaults to 'true'	.invalidResponse('true')
wildcard(string)	string	async validators uses a place holder to replace the value on the string of the url, defaults to '{value}'	wildcard(':value')

All asyncValidatorProvider return the asyncValidatorProvider instance for easy chaining.

To use the directive simply include it in your html:

<form name='form'>
    <input type='text' ng-model='value' name='value' async-valid='username'>
</form>

You can override some global values from the directive itself like this

attribute	value	function that overrides
async-default-state	string	defaultState(state)
async-invalid-response	string	invalidResponse(response)
async-min-length	int, string	minLength(length)
async-valid-response	string	validResponse(response)

** if you have any problems with async-valid create an issue on Github

Validator service

Angular validators exposes validatorjs as an angular service named nodeValidator. More on validator.js
