How to Rebuild a Complex React Admin Panel from Video to Code with Replay: A Full Tutorial

TL;DR: Learn how to use Replay to automatically generate a React admin panel from a simple video recording, saving you countless hours of manual coding.

The dream of automatically generating functional UIs from simple inputs is now a reality. Forget painstakingly coding every component and interaction. With Replay, you can reconstruct complex interfaces, like admin panels, directly from video demonstrations. This tutorial will guide you through the entire process, showcasing how Replay leverages behavior-driven reconstruction to create working code.

Why Video-to-Code is a Game Changer#

Building complex UIs, especially admin panels, is notoriously time-consuming. Traditional methods involve:

• •Designing the UI in Figma or similar tools
• •Writing React components from scratch
• •Connecting the UI to a backend API
• •Implementing state management and user interactions
• •Testing and debugging the entire application

This process can take weeks, even months, depending on the complexity of the panel. Screenshot-to-code tools offer a partial solution, but they often fail to capture the behavior of the UI, resulting in static interfaces that require significant manual intervention.

Replay changes the game by analyzing video recordings of user interactions. It understands what the user is trying to achieve, not just what they see on the screen. This behavior-driven approach allows Replay to generate functional code that accurately reflects the intended user experience.

Understanding Behavior-Driven Reconstruction#

Replay's core innovation lies in its ability to understand user behavior from video. This is achieved through a multi-stage process:

1. •Video Analysis: Replay analyzes the video frame-by-frame, identifying UI elements, user actions (clicks, scrolls, form inputs), and transitions between pages.
2. •Behavioral Modeling: Based on the video analysis, Replay builds a behavioral model of the UI. This model captures the relationships between UI elements, user actions, and application state.
3. •Code Generation: Replay uses the behavioral model to generate React code, including components, state management logic, API calls, and event handlers.

This approach offers several advantages over traditional and screenshot-to-code methods:

• •Reduced Development Time: Replay automates the most tedious parts of UI development, allowing you to focus on higher-level tasks.
• •Improved Accuracy: By understanding user behavior, Replay generates code that accurately reflects the intended user experience.
• •Increased Flexibility: Replay can handle complex UIs with multiple pages, forms, and interactions.

Setting Up Your Environment#

Before we dive into the tutorial, let's make sure you have the necessary tools and environment setup:

1. •

   Node.js and npm: Ensure you have Node.js and npm (or yarn) installed on your machine. You can download them from the official Node.js website.

   bash
   node -v
   npm -v

2. •

   React Development Environment: You'll need a React development environment. You can use Create React App or any other React framework you prefer.

   bash
   npx create-react-app my-admin-panel
   cd my-admin-panel

3. •

   Replay Account: You'll need a Replay account to access the video-to-code engine. You can sign up for a free trial on the Replay website.

Rebuilding the Admin Panel: A Step-by-Step Tutorial#

Step 1: Recording the Video#

The first step is to record a video of yourself interacting with the admin panel. The video should clearly demonstrate all the key features and interactions you want to reconstruct.

💡 Pro Tip: Speak clearly while recording and highlight the different features you want Replay to capture. This will help Replay better understand your intentions.

Here are some tips for recording a good video:

• •Showcase Key Features: Make sure to demonstrate all the essential features of the admin panel, such as user management, data visualization, and settings.
• •Demonstrate User Interactions: Clearly show how users interact with the UI, including clicks, form inputs, and navigation.
• •Use a Clean and Consistent UI: Ensure that the UI in the video is clean, consistent, and well-designed. This will help Replay accurately identify UI elements.
• •Keep it Concise: Aim for a video that is between 2 and 5 minutes long. This will provide enough information for Replay to generate accurate code without being overly verbose.

Step 2: Uploading the Video to Replay#

Once you have recorded the video, upload it to Replay. You can do this by logging into your Replay account and clicking the "Upload Video" button.

📝 Note: Replay supports various video formats, including MP4, MOV, and AVI.

Step 3: Configuring Replay Settings#

After uploading the video, you'll need to configure Replay settings. These settings allow you to customize the code generation process.

• •Target Framework: Select "React" as the target framework.
• •Output Language: Choose "TypeScript" or "JavaScript" as the output language.
• •Styling Method: Select your preferred styling method (e.g., CSS Modules, Styled Components, Tailwind CSS). Replay supports style injection, allowing you to seamlessly integrate the generated code into your existing project.
• •Supabase Integration: If your admin panel uses Supabase for backend services, enable the Supabase integration. Replay will automatically generate the necessary API calls and data models.

Step 4: Generating the Code#

Once you have configured the settings, click the "Generate Code" button. Replay will analyze the video and generate the React code for the admin panel. This process may take a few minutes, depending on the complexity of the video.

Step 5: Reviewing and Refining the Code#

After the code generation is complete, review the generated code. Replay provides a code editor that allows you to inspect and modify the code.

⚠️ Warning: While Replay strives for accuracy, the generated code may require some manual refinement. Pay close attention to the following areas:

• •Styling: Ensure that the styling is consistent with your existing project.
• •State Management: Verify that the state management logic is correct and efficient.
• •API Calls: Double-check that the API calls are properly configured and handle errors correctly.

Here's an example of the generated React code for a user management component:

typescript
// UserManagement.tsx
import React, { useState, useEffect } from 'react';
import { supabase } from './supabaseClient';

interface User {
  id: string;
  name: string;
  email: string;
}

const UserManagement = () => {
  const [users, setUsers] = useState<User[]>([]);

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

      if (error) {
        console.error('Error fetching users:', error);
        return;
      }

      setUsers(data || []);
    };

    fetchUsers();
  }, []);

  return (
    <div>
      <h2>User Management</h2>
      <ul>
        {users.map(user => (
          <li key={user.id}>
            {user.name} - {user.email}
          </li>
        ))}
      </ul>
    </div>
  );
};

export default UserManagement;

This code snippet demonstrates how Replay can automatically generate React components with data fetching logic. In this case, it fetches user data from a Supabase database.

Step 6: Integrating the Code into Your Project#

Once you have reviewed and refined the code, integrate it into your existing React project. Copy the generated components, styles, and API calls into your project directory.

Step 7: Testing and Debugging#

Finally, test the integrated code thoroughly. Ensure that all the features and interactions work as expected. Debug any issues that arise.

Replay Features That Simplify Development#

Replay offers a range of features that simplify the development process:

• •Multi-Page Generation: Replay can generate code for multi-page applications, capturing the navigation flow and interactions between pages.
• •Supabase Integration: Replay seamlessly integrates with Supabase, automatically generating API calls and data models.
• •Style Injection: Replay supports style injection, allowing you to integrate the generated code into your existing project without conflicts.
• •Product Flow Maps: Replay generates product flow maps that visualize the user journey through the application. This helps you understand how users interact with the UI and identify potential areas for improvement.
