React-hook-form is a highly performant, flexible, and extensible forms library designed specifically for React Hooks. It focuses on providing excellent user experience and developer experience. React-hook-form embraces the native HTML form validation, enabling integration with several UI libraries out of the box. Moreover, it's a lightweight package with no dependencies and supports popular validation libraries such as Yup, Zod, AJV, Superstruct, Joi, among others.

To use react-hook-form in your React application, first, you need to install the npm package using the command npm install react-hook-form. Here's a simple example demonstrating the usage of react-hook-form.

import { useForm } from 'react-hook-form';

function App() {
  const {
    register,
    handleSubmit,
    formState: { errors },
  } = useForm();

  return (
    <form onSubmit={handleSubmit((data) => console.log(data))}>
      <input {...register('firstName')} />
      <input {...register('lastName', { required: true })} />
      {errors.lastName && <p>Last name is required.</p>}
      <input {...register('age', { pattern: /\d+/ })} />
      {errors.age && <p>Please enter a number for age.</p>}
      <input type="submit" />
    </form>
  );
}
