Need I say this? The React Hooks API is still very experimental and not recommended for production code.

npm install --save react-final-form-hooks final-form

or

yarn add react-final-form-hooks final-form

🏁 React Final Form Hooks is the leanest possible way to connect 🏁 Final Form to React, to acheive subscriptions-based form state management using the Observer pattern.

If performance is your goal, you are recommended to use 🏁 React Final Form. Also, that library does many other things for you, like managing checkbox and radio buttons properly. RFFHooks leaves all of that work to you. By default, 🏁 React Final Form Hooks subscribes to all changes, but if you want to fine tune your form, you may specify only the form state that you care about for rendering your gorgeous UI.

Here's what it looks like in your code:

import { useForm, useField } from 'react-final-form-hooks'

const MyForm = () => {
  const { form, handleSubmit, values, pristine, submitting } = useForm({
    onSubmit, // the function to call with your form values upon valid submit
    validate // a record-level validation function to check all form values
  })
  const firstName = useField('firstName', form)
  const lastName = useField('lastName', form)
  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label>First Name</label>
        <input {...firstName.input} placeholder="First Name" />
        {firstName.meta.touched &&
          firstName.meta.error && <span>{firstName.meta.error}</span>}
      </div>
      <div>
        <label>Last Name</label>
        <input {...lastName.input} placeholder="Last Name" />
        {lastName.meta.touched &&
          lastName.meta.error && <span>{lastName.meta.error}</span>}
      </div>
      <button type="submit" disabled={pristine || submitting}>
        Submit
      </button>
    </form>
  )
}
