How do I migrate from React Hook Form to Formik?

Migrating from React Hook Form to Formik involves a few key steps. First, you'll need to install Formik if you haven't already.

What are the main differences between the two libraries?

React Hook Form is more focused on performance and uses uncontrolled components, while Formik is more about managing form state and validation.

Can you show me a code example of the migration?

Sure! Here's a simple example:

1. Replace useForm from React Hook Form with Formik component.
2. Use Field components for inputs.

Would you like to see a specific form example?

Yes, please provide an example with validation.

Here's a basic example with validation using Formik:

<Formik
  initialValues={{ name: '' }}
  validate={values => {
    const errors = {};
    if (!values.name) {
      errors.name = 'Required';
    }
    return errors;
  }}
  onSubmit={(values) => {
    console.log(values);
  }}
>
  {({ handleSubmit }) => (
    <form onSubmit={handleSubmit}>
      <Field name="name" />
      <button type="submit">Submit</button>
    </form>
  )}
</Formik>
