Forms Validation with Angular made easy! Angular-Validation is an angular Directive/Service with locales (language translation) with a very simple approach of defining your validation directly within your element to validate (input, textarea, etc) and...that's it!!! The Directive/Service will take care of the rest! For example: <input name="firstname" validation="alpha|min_len:5|max_len:50|required" ng-model="user.firstname" />
