Use validation without saving the form data to the database

Is it possible to use validation without necessarily having to save the data in the database, but only check if the data sent meets the rules?

I need to check that the form contains data according to certain rules, but I don't have to save it, but return it to javascript to append an element, only if I pass the validation

How can I perform the validation without performing an insert or an update?

The Validation class is a stand alone library. You can use it without database.

Thanks, I was immersed in In-Model Validation and had the thing removed
