How do I install Formik in my React project?

To install Formik, you can use npm or yarn. Run npm install formik or yarn add formik in your project directory.

Do I need to install any other packages with Formik?

No, Formik is a standalone library, but you might want to install Yup for validation, which is commonly used with it.

Can you show me a basic example of using Formik?

Sure! Here's a simple example:

import { Formik, Form, Field } from 'formik';

const MyForm = () => (
  <Formik
    initialValues={{ name: '' }}
    onSubmit={values => { console.log(values); }}
  >
    <Form>
      <Field name="name" placeholder="Enter your name" />
      <button type="submit">Submit</button>
    </Form>
  </Formik>
);

This creates a basic form with a single input.

What if I want to add validation to my form?

You can use Yup for validation. First, install it with npm install yup, then define a validation schema and pass it to Formik.
