Reusable form fields and form libraries

🏠The everyday picture

A printing press with a standard form template: every field already has a label, a box, and a space for corrections. Staff just choose the questions.

📘What it really is

Repeating label, input, error and ARIA attributes for every field is tedious and easy to get wrong. Make a component:

interface TextFieldProps {
  id: string;
  label: string;
  value: string;
  error?: string;
  type?: "text" | "email" | "tel";
  onChange: (event: React.ChangeEvent<HTMLInputElement>) => void;
  onBlur: () => void;
}

It renders the label, input, error and connections in one place, correctly every time.

Form libraries such as React Hook Form (often with Zod) handle state, touched fields, validation and submission for larger forms with less code. Real projects and AI often use them; now you know what they do for you.
Whatever the tool, the checks are the same: labels, clear errors at the right time, focus management, server validation.

🖱️Try it

Create TextField and TextAreaField components and rebuild the enquiry form with them. The form should behave exactly as before; the code should be much shorter. Run your validation tests again.
