What is React?

React is a popular open-source JavaScript library used for building user interfaces. It provides a declarative and component-based architecture that makes creating user interfaces simple and intuitive. In this guide, we’ll show you how to integrate your Formbox form with React.

​
Prerequisites

Before you begin, you’ll need to have a Formbox form. If you don’t have one yet, you can create a new form by following the steps in the Introduction guide. Once you have your form, make a note of the form’s endpoint url in the setup tab of your form page, as you’ll need it later.

​
Creating a new React project

o get up and running quickly, let’s use Vite to bootstrap a single-page React application. In your terminal, run the following command to create a new project: 
npm create vite@latest react-with-formbox -- --template react
Once everything is installed you will see a terminal message with instructions for navigating to your site and running it locally. Go to the new directory for the new website: 
cd react-with-formbox
Start the development server: 
npm run dev
Open your browser and navigate to http://localhost:5173. You should see a new React application running.

​
Adding your Formbox form to your React project

Now that we have a new React project set up, let’s add our Formbox form to it. For styling purposes, we’ll use Tailwind CSS. You can learn how to add Tailwind CSS to your project by following the React installation guide. Once you have Tailwind CSS set up, let’s add our form. Open up the App.js file within the src directory and replace everything in the file with the following code block:
App.js
import './App.css';

export default function App() {
  return (
    <div className="max-w-md mx-auto py-20 bg-white">
      <h2 className="text-2xl font-semibold mb-6">Get in Touch</h2>
      <form action="https://api.formbox.app/s/{your-form-id}" method="POST">
        <div className="mb-4">
          <label
            htmlFor="name"
            className="block text-gray-700 text-sm font-bold mb-2"
          >
            Name
          </label>
          <input
            type="text"
            id="name"
            name="name"
            placeholder="John Doe"
            required
            className="w-full px-3 py-2 border rounded-md focus:outline-none focus:border-blue-500"
          />
        </div>
        <div className="mb-4">
          <label
            htmlFor="email"
            className="block text-gray-700 text-sm font-bold mb-2"
          >
            Email
          </label>
          <input
            type="email"
            id="email"
            name="email"
            placeholder="john@example.com"
            required
            className="w-full px-3 py-2 border rounded-md focus:outline-none focus:border-blue-500"
          />
        </div>
        <div className="mb-6">
          <label
            htmlFor="message"
            className="block text-gray-700 text-sm font-bold mb-2"
          >
            Message
          </label>
          <textarea
            id="message"
            name="message"
            rows={4}
            placeholder="How can we help you?"
            className="w-full px-3 py-2 border rounded-md focus:outline-none focus:border-blue-500"
          ></textarea>
        </div>
        <button
          type="submit"
          className="bg-blue-500 text-white px-4 py-2 rounded-md hover:bg-blue-600 focus:outline-none focus:shadow-outline-blue"
        >
          Send Message
        </button>
      </form>
    </div>
  );
}
Paste the form endpoint url you copied from Formbox into your form’s action attribute as shown in the code block above. Save the file and navigate to http://localhost:5173 in your browser. You should see a form that you can fill out and submit.
And that’s it! Now after filling out and submitting the form you should see the default submission success page displayed.
