Form validation is a difficult subject in frontend, not only you have to deal with ensuring correct values are submitted, you also should provide a pleasant UX for your users. Doing form validation by hand is a lot of work and you won't probably cover all your needs if you decide to build your own. The time you spend working on a custom form validation solution is better spent building your application logic. Most validation libraries will save you a lot of time, but vee-validate tackles the major pain points of form validation and addresses them in a very flexible way:. You can define validation rules for your fields using the useField composition API function, your rules can be as simple as a function that accepts the current value and returns an error message. The validation happens automatically when value binding changes, meaning you can use useField to trigger validation for any kind of data and not just for inputs. Instead of providing validations for each field individually which can clutter your code, you can instead define the validation schema using the useForm function by passing a validationSchema option. Each field will automatically be associated with it and will be validated accordingly. A simple validation schema can be an object containing field names as keys and validation functions as the value for those keys. Fortunately there is already a very neat way to build validation schemas for your forms by using yup , it allows you create validation objects like this:. Vue HTML. NET Core. Codeigniter Soon.
