Managing Form State
When building forms with React Hook Form, you have access to several powerful form state properties that help you manage and respond to user interactions. Some of the most important properties include errors, touchedFields, isDirty, and isValid.
The errors property contains validation error messages for each field, allowing you to inform users about issues as they fill out the form. The touchedFields property tracks which fields have been interacted with, so you can decide when to show validation feedback. The isDirty property tells you if any field value has changed from its initial state, which is useful for prompting users about unsaved changes. The isValid property is a boolean that becomes true when the entire form passes validation, and false otherwise.
You can use these properties to create a smoother and more user-friendly experience. For example, you might display error messages only after a field has been touched, or disable the submit button until the form is valid. By leveraging these properties, you ensure users receive timely feedback and prevent incomplete or incorrect submissions.
