How to Recreate a Healthcare Dashboard from Video to React with Tailwind and Replay

TL;DR: Recreate a fully functional React healthcare dashboard with Tailwind CSS directly from a screen recording using Replay, leveraging its behavior-driven reconstruction capabilities.

The holy grail of frontend development? Turning ideas into reality instantly. Screenshot-to-code tools offered a glimpse, but fell short of capturing the behavior behind the visuals. Now, with Replay, you can reconstruct entire UIs, complete with logic and styling, directly from video recordings. This tutorial will demonstrate how to recreate a healthcare dashboard from video to React with Tailwind CSS.

Why Video-to-Code is a Game Changer#

Traditional methods of UI development are time-consuming. They involve:

1. •Designing mockups (Figma, Sketch, etc.)
2. •Hand-coding the UI components.
3. •Integrating with backend services.
4. •Testing and iterating.

Video-to-code, especially with Replay's behavior-driven approach, streamlines this process. Instead of static screenshots, Replay analyzes user interactions within the video, understanding the intent behind each click, scroll, and form entry. This results in more accurate and functional code generation.

Replay: Behavior-Driven Reconstruction#

Replay uses Gemini to understand the nuances of user behavior captured in a video recording. This "Behavior-Driven Reconstruction" translates into several key advantages:

• •Multi-page Generation: Replay can generate code for complex, multi-page applications, understanding the navigation flow between screens.
• •Supabase Integration: Seamlessly integrate your generated dashboard with Supabase for data persistence and real-time updates.
• •Style Injection: Replay intelligently applies Tailwind CSS classes based on the visual elements in the video, ensuring a consistent and modern design.
• •Product Flow Maps: Visualize the user journey through your application, gaining insights into user behavior and identifying areas for improvement.

Recreating a Healthcare Dashboard: A Step-by-Step Guide#

Let's walk through recreating a healthcare dashboard from a screen recording using Replay. We'll assume you have a video showcasing the dashboard's functionality and design.

Step 1: Prepare Your Video#

Ensure your video recording is clear and demonstrates all the key interactions within the healthcare dashboard. Focus on capturing:

• •Navigation between different sections (e.g., patient lists, appointment scheduling, reports).
• •Data input and form submissions.
• •Interactive elements like charts and graphs.
• •Overall visual design and styling.

💡 Pro Tip: A well-structured video is crucial for accurate code generation. Use clear and deliberate actions while recording. Avoid unnecessary pauses or distractions.

Step 2: Upload to Replay#

1. •Go to Replay's website and create an account.
2. •Upload your video recording.
3. •Replay will begin analyzing the video and reconstructing the UI. This process may take a few minutes depending on the video's length and complexity.

Step 3: Review and Refine the Generated Code#

Once Replay completes the reconstruction, you'll be presented with the generated React code, complete with Tailwind CSS styling.

1. •Inspect the Code: Examine the code for each component, paying attention to the structure, styling, and event handlers.
2. •Refine the Styling: While Replay intelligently applies Tailwind CSS, you may need to adjust some classes to achieve the desired look and feel.
3. •Implement Data Fetching: Replay can generate placeholders for data fetching. You'll need to integrate with your chosen backend (e.g., Supabase) to populate the dashboard with real data.

Here's an example of a generated React component with Tailwind CSS:

typescript
// Generated by Replay
import React from 'react';

interface PatientCardProps {
  name: string;
  age: number;
  condition: string;
}

const PatientCard: React.FC<PatientCardProps> = ({ name, age, condition }) => {
  return (
    <div className="bg-white rounded-lg shadow-md p-4 w-64">
      <h2 className="text-xl font-semibold mb-2">{name}</h2>
      <p className="text-gray-600">Age: {age}</p>
      <p className="text-gray-600">Condition: {condition}</p>
      <button className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded mt-4">
        View Details
      </button>
    </div>
  );
};

export default PatientCard;

This code defines a

component with basic patient information and a "View Details" button. The Tailwind CSS classes provide the styling for the card, including background color, rounded corners, shadow, and text styles.

Step 4: Integrate with Supabase (Optional)#

If you want to persist and manage the data displayed in your dashboard, you can integrate with Supabase. Replay can generate the necessary code to connect to your Supabase database and fetch data.

1. •Set up a Supabase Project: Create a new Supabase project and define the necessary tables for your healthcare data (e.g., patients, appointments, medications).
2. •Configure Replay: Provide Replay with your Supabase API key and URL.
3. •Generate Data Fetching Code: Replay will generate React hooks and functions to fetch data from your Supabase tables.

Here's an example of a generated data fetching hook:

typescript
// Generated by Replay
import { useEffect, useState } from 'react';
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;

const supabase = createClient(supabaseUrl!, supabaseKey!);

interface Patient {
  id: number;
  name: string;
  age: number;
  condition: string;
}

const usePatients = () => {
  const [patients, setPatients] = useState<Patient[]>([]);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState<Error | null>(null);

  useEffect(() => {
    const fetchPatients = async () => {
      try {
        const { data, error } = await supabase
          .from('patients')
          .select('*');

        if (error) {
          throw error;
        }

        setPatients(data as Patient[]);
        setLoading(false);
      } catch (error: any) {
        setError(error);
        setLoading(false);
      }
    };

    fetchPatients();
  }, []);

  return { patients, loading, error };
};

export default usePatients;

This hook uses the

library to fetch patient data from the table in your Supabase database. It returns the array, a state, and an state.

Step 5: Implement Interactive Elements#

The video analysis allows Replay to detect interactive elements like buttons, charts, and forms. You'll need to implement the corresponding event handlers and logic to make these elements functional.

For example, if your dashboard includes a chart displaying patient data, you'll need to integrate a charting library like Chart.js or Recharts and populate the chart with data from your Supabase database.

📝 Note: Replay provides a solid foundation for your UI. However, complex logic and data handling will still require manual implementation.

Replay vs. Traditional Methods and Screenshot-to-Code Tools#

Let's compare Replay with traditional UI development methods and existing screenshot-to-code tools:

As the table illustrates, Replay bridges the gap between speed and accuracy, offering a significant advantage over traditional methods and screenshot-to-code tools.
