React Hook Form

React Hook Form tracks what someone enters in a form and which checks fail.

What does React Hook Form handle after you have an input?

Connect the input to React Hook Form and give it rules, such as requiring a name. The helper tracks values and failed checks. The form fields, labels, styling and save action come from your app or a separate visual library.

Use the app’s server to check the submitted values again if the form changes saved data. Browser validation gives feedback during entry.

How does a keyboard user find a mistake?

Give the field a visible label and connect a specific error message to the field. The helper can move focus to the first invalid field in a short form when its input reference is connected. In a longer form, you can move focus to a summary with links to the affected fields.

Try submitting without touching the mouse. Check whether the error is understandable without relying on red color.

What stays in your project?

React Hook Form is MIT-licensed. Keep your field rules, error wording and submit logic with the React project. If you replace an input with a custom control, check that focus still reaches the actual input.

What should a visitor see when Save cannot proceed?

Sketch a fictional display-name form. Use no saved customer data or server connection.

  1. Leave the required field blank
    Write an error that tells the person what to enter and show it next to the field.
  2. Mark the next keyboard step
    Show where focus goes after submitting, and leave the form available for a correction.
  3. Separate a valid form from a successful save
    Draw a different message for a failed save. Confirm success only after the app reports that it saved.
