Reactjs - React-datepicker with a Formik form

Integrating react-datepicker with a Formik form in a React application allows you to manage date inputs efficiently within forms. Formik simplifies form handling in React by managing form state, validation, and submission. Here's a step-by-step guide on how to integrate react-datepicker with Formik:

Step-by-Step Integration

  1. Setup React Project and Install Dependencies:

    Make sure you have a React project set up. If not, you can create one using create-react-app:

    npx create-react-app my-form-app cd my-form-app

    Install formik and react-datepicker:

    npm install formik react-datepicker

  2. Create a Form Component:

    Create a form component that uses Formik for managing form state and validation:

    // src/components/MyForm.js import React from 'react'; import { Formik, Form, Field } from 'formik'; import DatePicker from 'react-datepicker'; import 'react-datepicker/dist/react-datepicker.css'; const MyForm = () => { const initialValues = { name: '', email: '', birthDate: null }; const handleSubmit = (values) => { console.log(values); // Handle form submission logic here }; return ( <Formik initialValues={initialValues} onSubmit={handleSubmit} > {({ setFieldValue }) => ( <Form> <div> <label htmlFor="name">Name:</label> <Field id="name" name="name" type="text" /> </div> <div> <label htmlFor="email">Email:</label> <Field id="email" name="email" type="email" /> </div> <div> <label htmlFor="birthDate">Birth Date:</label> <DatePicker id="birthDate" name="birthDate" selected={values.birthDate} onChange={(date) => setFieldValue('birthDate', date)} dateFormat="dd/MM/yyyy" /> </div> <button type="submit">Submit</button> </Form> )} </Formik> ); }; export default MyForm;
    • Explanation:
      • Formik Component: Manages form state and handles form submission.
      • DatePicker Component: Integrated with Formik using setFieldValue to update the form state (birthDate field).
      • onChange: Updates the birthDate field in Formik state when the date is selected in DatePicker.

  3. Integrate Form Component in App:

    Update App.js to render MyForm component:

    // src/App.js import React from 'react'; import MyForm from './components/MyForm'; function App() { return ( <div className="App"> <h1>React Datepicker with Formik Form</h1> <MyForm /> </div> ); } export default App;

  4. Styling (Optional):

    Style your form and datepicker according to your application's design requirements.

  5. Run Your Application:

    Start your application to see the form with react-datepicker in action:

    npm start

Notes:

  • Date Formatting: Customize dateFormat prop in DatePicker as per your requirements.
  • Validation: Implement validation using Formik's validation schema or custom validation functions.
  • Submit Handling: Define handleSubmit function to handle form submission logic.

By following these steps, you can effectively integrate react-datepicker with a Formik form in your React application, providing a robust solution for managing date inputs within forms with state management, validation, and submission capabilities. Adjust the form fields and logic to suit your specific application requirements.
