How to Convert UI/UX Mockups in Video to Working React Code Using Replay in 5 Steps

TL;DR: Replay converts UI/UX mockup videos into production-ready React code by analyzing user behavior and generating functional components with Supabase integration, style injection, and product flow mapping.

Generating code from UI/UX mockups has traditionally been a tedious, manual process. Existing screenshot-to-code tools offer a partial solution, but they often fall short of capturing the nuances of user interaction and translating them into functional code. They see the what, not the why. Replay addresses this gap by analyzing videos of UI/UX mockups and reconstructing them into working React code, understanding user behavior and intent through Behavior-Driven Reconstruction.

Replay: Behavior-Driven Reconstruction from Video#

Replay takes a revolutionary approach: it treats video as the source of truth. Instead of simply converting static images, Replay analyzes the dynamics of the video – the clicks, scrolls, and data inputs – to understand the intended user experience. This allows Replay to generate code that not only looks like the mockup but also behaves like it.

How Replay Differs From Existing Solutions#

The key differentiator lies in Replay's ability to analyze video and derive meaning from user interactions. Consider the following comparison:

As the table illustrates, Replay offers a more comprehensive solution by understanding user intent and generating more robust and functional code. Existing screenshot-to-code tools are limited by their inability to interpret user actions. Replay bridges this gap.

Converting UI/UX Mockups to React Code: A 5-Step Guide#

Here's a step-by-step guide on how to convert UI/UX mockups in video to working React code using Replay:

Step 1: Prepare Your Mockup Video#

The first step is to create a clear and concise video of your UI/UX mockup.

💡 Pro Tip: Ensure the video demonstrates the complete user flow, including all interactions and transitions between pages. A well-defined video will result in more accurate and functional code.

Consider these best practices:

• •Resolution: Aim for a resolution of at least 720p for optimal clarity.
• •Pace: Maintain a moderate pace, allowing Replay to accurately capture each interaction.
• •Clarity: Avoid unnecessary distractions in the background.
• •User Flow: Explicitly demonstrate the intended user flow, including all clicks, scrolls, and data inputs.

Step 2: Upload Your Video to Replay#

Navigate to the Replay platform and upload your mockup video. Replay supports various video formats, including MP4, MOV, and WebM.

📝 Note: The upload process may take some time depending on the size of your video and your internet connection.

Step 3: Configure Replay Settings#

After uploading your video, you'll be presented with configuration options. These settings allow you to customize the code generation process to meet your specific requirements.

• •Framework: Select React as the target framework.
• •Styling: Choose your preferred styling method (e.g., CSS Modules, Styled Components, Tailwind CSS). Replay supports style injection, allowing you to seamlessly integrate your existing styling conventions.
• •Supabase Integration: Enable Supabase integration if your mockup utilizes Supabase for backend services. Replay will automatically generate the necessary code to connect your React components to your Supabase database.
• •Component Naming: Define a naming convention for the generated components.
• •Page Segmentation: Define how Replay should segment the video into individual pages. Replay uses AI to automatically detect page transitions, but you can manually adjust these segments for greater accuracy.

Step 4: Generate the React Code#

Once you've configured the settings, initiate the code generation process. Replay will analyze your video and generate React code based on the identified user interactions and design elements.

This process leverages Replay's Behavior-Driven Reconstruction engine, which analyzes the video to understand the intended user experience. Replay doesn't just generate code based on visual appearance; it understands what the user is trying to accomplish and generates code that reflects that intent.

Step 5: Integrate and Customize the Generated Code#

After the code generation process is complete, you can download the generated React code as a ZIP file or directly integrate it into your existing project via Git integration.

⚠️ Warning: While Replay generates highly functional code, some manual customization may be required to fine-tune the user interface and implement advanced features.

Here's an example of a generated React component:

typescript
// Generated by Replay
import React, { useState, useEffect } from 'react';
import { supabase } from './supabaseClient'; // Assuming Supabase integration

interface Todo {
  id: number;
  task: string;
  completed: boolean;
}

const TodoList: React.FC = () => {
  const [todos, setTodos] = useState<Todo[]>([]);

  useEffect(() => {
    fetchTodos();
  }, []);

  const fetchTodos = async () => {
    const { data, error } = await supabase
      .from('todos')
      .select('*');

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

    setTodos(data || []);
  };

  return (
    <div>
      <h2>Todo List</h2>
      <ul>
        {todos.map(todo => (
          <li key={todo.id}>{todo.task}</li>
        ))}
      </ul>
    </div>
  );
};

export default TodoList;

This code snippet demonstrates how Replay can automatically integrate with Supabase, fetching data and rendering it in a React component. This drastically reduces the amount of boilerplate code you need to write manually.

Replay also generates product flow maps, visualizing the user journey through your application. This provides valuable insights into user behavior and helps you identify potential areas for improvement.

Benefits of Using Replay#

Replay offers several key benefits for developers and designers:

• •Faster Development: Automate the code generation process, reducing development time and effort.
• •Improved Accuracy: Generate code that accurately reflects the intended user experience.
• •Seamless Integration: Integrate with popular frameworks and backend services, such as React and Supabase.
• •Enhanced Collaboration: Facilitate collaboration between designers and developers by providing a shared understanding of the user interface.
• •Reduced Errors: Minimize manual coding errors by automating the code generation process.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features and usage. Paid plans are available for users who require more advanced features and higher usage limits.

How is Replay different from v0.dev?#

While both Replay and v0.dev aim to generate code, they differ significantly in their approach. v0.dev primarily focuses on generating code from text prompts, while Replay analyzes videos of UI/UX mockups to understand user behavior and generate functional code. Replay's Behavior-Driven Reconstruction provides a more accurate and comprehensive representation of the intended user experience. Replay understands interaction, not just static design.

What styling options does Replay support?#

Replay supports various styling options, including CSS Modules, Styled Components, and Tailwind CSS. You can choose your preferred styling method during the configuration process.

Can Replay handle complex user flows?#

Yes, Replay is designed to handle complex user flows. By analyzing the video, Replay can identify all interactions and transitions between pages, generating code that accurately reflects the intended user experience.

What if the generated code requires customization?#

While Replay generates highly functional code, some manual customization may be required to fine-tune the user interface and implement advanced features. Replay provides a solid foundation, allowing you to focus on the more complex aspects of your application.
