              name: 'M'
          })
          .setValidations({
            name: {
                validators.notNull,
                minLenght: validators.minLength(2)
            }
        })

Examples

Array validation

const arrayValidation = new ValidatorBuilder()
  .setValue([1, 2, 3])

Custom validation

const userValidation = new ValidatorBuilder()
  .setValue({ name: 'Jonh', age: 21 })
  .notNull()
  .customValidation(user => user.age >= 18)
  .validate()

  if (!userValidation.isValid()) {
    alert(userValidation.getErrorMessage())
  }
