How can I implement conditional validations in Vuelidate?

You can implement conditional validations in Vuelidate by using the requiredIf validator or creating custom validators.

Can you show me an example of using requiredIf?

Sure! Here's a simple example:

validations: {
  fieldA: { requiredIf: vm => vm.fieldB === 'yes' },
  fieldB: { required: true }
}

This means fieldA is required only if fieldB is 'yes'.

What if I need more complex conditions?

For complex conditions, you can create a custom validator. Here's an example:

validations: {
  fieldA: { customCondition: value => value.length > 5 && vm.fieldB === 'yes' }
}

This checks if fieldA has more than 5 characters and fieldB is 'yes'.
