Input Validator

• check the input validity with specified rules
• only the validated attribute(s) are returned
• convert data type on validating, e.g '100' to 100 for 'type:number'

• rules

  • required
  • type:string|date|datetime|isoDatetime|number|email|bool|boolean|null|nonEmptyString|object
  • same:attributeName

• validator:: obj -> obj -> obj

• examples
