What is Remix?

Remix is a full stack web framework that lets you focus on the user interface and work back through web standards to deliver a fast, slick, and resilient user experience.

​
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 Remix project

To get up and running quickly, we will follow the official Remix Quick Start guide to create a new Remix project. In your terminal, run the following command: 
npx create-remix@latest
After the prompts, create-remix will create a folder with your project name and install the required dependencies. Go to the new directory for the new website: 
cd remix-with-formbox
Start the development server: 
npm run dev
Open your browser and navigate to http://localhost:5174. You should see a new Remix application running.

​
Adding your Formbox form to your Remix project

Now that we have a new Remix 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 Remix installation guide. Once you have Tailwind CSS set up, let’s add our form. Open up the _index.tsx file within the root of the app/routes directory and replace everything in the file with the following code block:
_index.tsx
import type { MetaFunction } from '@remix-run/node';

export const meta: MetaFunction = () => {
  return [{ title: 'Remix with Formbox' }];
};

export default function Index() {
  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:5174 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.
