Effective Form Validation in Vue 3 Using Vee-Validate 4
Written on
Chapter 1: Understanding Vee-Validate 4
Form validation plays a crucial role in the functionality of any application. In this article, we will explore how to effectively implement Vee-Validate 4 for form validation in a Vue 3 application.
This video titled "VeeValidate: Your Key to Easy Vue Form Validation" provides an insightful overview of how Vee-Validate simplifies the form validation process in Vue apps.
Section 1.1: Utilizing Yup Schemas
To ensure our validation schemas are non-reactive, we can avoid the unnecessary overhead of reactivity. This can be achieved by either integrating the schema within the setUp method or using the markRaw function on our schema.
For instance, we can define our schema in the setUp method like this:
// Example of creating a schema in the setUp method
By returning the object generated by Yup, we ensure that the schema property remains non-reactive. Alternatively, we can employ markRaw as follows:
// Example of calling markRaw with our Yup schema
Section 1.2: Validating Radio Buttons
Vee-Validate 4 can effectively validate radio buttons. We can utilize the Field component with the type set to 'radio' to create our radio buttons. In the data method, we return the schema reactive property using the drink method to validate the selections.
The value property will hold the checked value as defined by the value prop. The method will return true if the choices are valid; otherwise, it provides an error message. The ErrorMessage component can be used to display any validation errors.

Chapter 2: Checkbox Validation
Checkbox validation can also be integrated using Vee-Validate 4. To add this feature, we set the type prop to 'checkbox' for rendering checkboxes. The drink method will collect all checked values in an array.
The method will return true if the selections are valid, and it will return an error message otherwise. Similar to radio buttons, we use the ErrorMessage component to present any validation issues.
Conclusion
By utilizing Yup schemas in a non-reactive manner, we can streamline the form validation process and effectively validate both radio buttons and checkboxes within our Vue 3 applications using Vee-Validate 4.
