Building React Apps from Adobe XD UI Designs

TL;DR: Stop manually translating Adobe XD designs into React code; Replay uses video analysis to reconstruct fully functional UIs, bridging the gap between design and development with behavior-driven code generation.

The age of painstakingly converting static designs into dynamic, interactive React applications is over. For too long, developers have been forced to manually translate Adobe XD layouts into functional code, a process rife with inconsistencies, errors, and wasted time. Screenshot-to-code tools offer a marginal improvement, but they fundamentally misunderstand the intent behind the design. They see pixels; they don't see workflows.

This is where behavior-driven reconstruction, powered by video analysis, changes everything. We need to move beyond visual representations and embrace a system that understands the how and why behind user interactions.

The Problem: Manual Design-to-Code Translation#

Consider the traditional workflow:

1. •A designer creates a beautiful UI in Adobe XD.
2. •The design is handed off to a developer.
3. •The developer meticulously recreates the design in React, manually coding each component, interaction, and state management logic.
4. •Testing and debugging reveal discrepancies between the intended design and the actual implementation.
5. •The process iterates, consuming valuable time and resources.

This manual process is not only inefficient but also prone to errors and inconsistencies. The developer's interpretation of the design might differ from the designer's intent, leading to a UI that looks visually similar but behaves differently.

Introducing Behavior-Driven Reconstruction#

Instead of relying on static screenshots or manual interpretation, what if we could capture the behavior of the intended UI through a video recording? What if we could analyze that video to understand the user flows, interactions, and state changes, and then automatically generate functional React code?

That's the core principle behind Replay. Replay analyzes video recordings of UI interactions to reconstruct fully functional React applications. It understands the intent behind the design, not just the visual appearance.

How Replay Works: Video-to-Code Engine#

Replay leverages the power of advanced video analysis and AI to bridge the gap between design and development. Here's a simplified breakdown of the process:

1. •Record: Capture a video of the intended UI interactions within Adobe XD (or any other design tool). This video serves as the source of truth for the desired application behavior.
2. •Analyze: Replay analyzes the video, identifying UI elements, user interactions (clicks, scrolls, form inputs), and state changes.
3. •Reconstruct: Using Gemini, Replay reconstructs the UI in React, generating clean, well-structured code that accurately reflects the behavior captured in the video.

This approach offers several key advantages:

• •Accuracy: The generated code accurately reflects the intended behavior of the UI, minimizing discrepancies and reducing the need for manual adjustments.
• •Efficiency: Automation significantly reduces the time and effort required to translate designs into code, freeing up developers to focus on more complex tasks.
• •Consistency: The generated code is consistent and predictable, ensuring a unified user experience across the application.

Replay Features: Beyond Basic Code Generation#

Replay goes beyond basic code generation by offering a range of features designed to streamline the development process:

• •Multi-Page Generation: Reconstruct entire multi-page applications from a single video recording.
• •Supabase Integration: Seamlessly integrate with Supabase for backend functionality, including data storage, authentication, and real-time updates.
• •Style Injection: Customize the look and feel of the generated UI by injecting custom CSS styles.
• •Product Flow Maps: Visualize the user flows within the application, providing a clear understanding of the intended user experience.

Replay vs. Traditional Methods & Screenshot-to-Code#

Let's compare Replay to traditional manual coding and screenshot-to-code tools:

This table clearly illustrates the advantages of Replay over traditional methods and screenshot-to-code tools. Replay's ability to analyze video and understand behavior results in more accurate, efficient, and maintainable code.

Building a React App from an Adobe XD Video: A Step-by-Step Guide#

Let's walk through a simple example of using Replay to build a React app from an Adobe XD video.

Step 1: Record the UI Interaction#

Record a video of yourself interacting with your Adobe XD design. Make sure to showcase all the key features, interactions, and state changes you want to capture. For example, if you're building a simple to-do list app, record yourself adding tasks, marking them as complete, and deleting them.

💡 Pro Tip: Speak clearly while recording, describing what you're doing. This can provide extra context for Replay's AI engine.

Step 2: Upload the Video to Replay#

Upload the video to Replay. Replay will automatically analyze the video and begin reconstructing the UI in React.

Step 3: Review and Refine the Generated Code#

Once the reconstruction is complete, review the generated code. Replay provides a user-friendly interface for inspecting the code, making adjustments, and adding custom styling.

Step 4: Integrate with Supabase (Optional)#

If you want to add backend functionality to your app, integrate with Supabase. Replay simplifies the process of connecting to Supabase and managing your data.

Step 5: Deploy Your React App#

Deploy your fully functional React app to your preferred hosting provider.

Code Example: Generated React Component#

Here's an example of the React code that Replay might generate for a simple button component:

typescript
// Generated by Replay
import React, { useState } from 'react';

interface ButtonProps {
  label: string;
  onClick: () => void;
}

const Button: React.FC<ButtonProps> = ({ label, onClick }) => {
  const [isHovered, setIsHovered] = useState(false);

  return (
    <button
      style={{
        backgroundColor: isHovered ? '#0056b3' : '#007bff',
        color: 'white',
        padding: '10px 20px',
        borderRadius: '5px',
        border: 'none',
        cursor: 'pointer',
      }}
      onMouseEnter={() => setIsHovered(true)}
      onMouseLeave={() => setIsHovered(false)}
      onClick={onClick}
    >
      {label}
    </button>
  );
};

export default Button;

This code is clean, well-structured, and accurately reflects the behavior of the button as captured in the video recording. It includes state management for hover effects and a customizable

handler.

⚠️ Warning: While Replay strives for accuracy, it's essential to review the generated code and make any necessary adjustments to ensure it meets your specific requirements.

The Future of UI Development#

Replay represents a significant step forward in UI development. By leveraging video analysis and AI, it automates the process of translating designs into code, freeing up developers to focus on more strategic tasks. This ultimately leads to faster development cycles, reduced costs, and more consistent user experiences.

📝 Note: Replay is continuously evolving, with new features and improvements being added regularly. Stay tuned for future updates and enhancements.

Frequently Asked Questions#

Is Replay free to use?#
