How to Reconstruct an E-commerce Product Page from Video to React with Replay: A 2026 Guide

TL;DR: Learn how to reconstruct a fully functional React-based e-commerce product page from a simple video recording using Replay's cutting-edge behavior-driven reconstruction engine.

The year is 2026. Screenshot-to-code tools are relics of the past. The new standard is video-to-code, and Replay is leading the charge. Imagine capturing a smooth product browsing experience on your favorite e-commerce site and transforming that video into a fully functional React component, complete with styling, data fetching, and even basic user interactions. This isn't science fiction; it's the power of behavior-driven reconstruction. This guide demonstrates how to reconstruct an e-commerce product page from a video into a working React component using Replay.

The Problem: Static Mockups vs. Dynamic Behavior#

Traditional UI development often starts with static mockups. While visually appealing, mockups fail to capture the dynamic behavior and user flows that are crucial for a seamless user experience. Building from scratch based on these mockups can be time-consuming and prone to errors. Screenshot-to-code tools offer a slight improvement, but they are limited by the static nature of images. They don't understand user intent, only visual representations.

Replay solves this problem by analyzing video recordings. It understands user behavior, detects transitions between states, and infers the underlying logic. This allows it to generate code that accurately reflects the intended user experience.

Replay: Behavior-Driven Reconstruction#

Replay uses video as the source of truth. By analyzing the visual elements and user interactions within the video, it reconstructs a functional UI component. This "Behavior-Driven Reconstruction" allows for a more accurate and efficient development process.

Here's how Replay stands out from the competition:

Reconstructing an E-commerce Product Page: A Step-by-Step Guide#

Let's walk through the process of reconstructing an e-commerce product page from a video using Replay. We'll assume you have a video recording of a user browsing a product page, interacting with different elements (e.g., selecting options, adding to cart), and navigating to related pages.

Step 1: Uploading the Video to Replay#

First, upload your video recording to the Replay platform. Replay supports various video formats (MP4, MOV, etc.) and automatically analyzes the content.

💡 Pro Tip: Ensure your video recording is clear and captures all relevant user interactions. A smooth, high-resolution recording will yield the best results.

Step 2: Replay's Analysis and Component Generation#

Replay's engine, powered by Gemini, analyzes the video, identifies UI elements, and infers the underlying logic. It then generates a React component representing the product page.

typescript
// Example generated React component (simplified)
import React, { useState, useEffect } from 'react';
import { supabase } from './supabaseClient'; // Assuming Supabase integration

interface Product {
  id: number;
  name: string;
  description: string;
  price: number;
  image_url: string;
  variants: { color: string; size: string }[];
}

const ProductPage: React.FC = () => {
  const [product, setProduct] = useState<Product | null>(null);
  const [selectedColor, setSelectedColor] = useState<string>('');
  const [selectedSize, setSelectedSize] = useState<string>('');

  useEffect(() => {
    const fetchProduct = async () => {
      // Inferred data fetching from video analysis (e.g., product ID)
      const productId = 123; // Replace with actual product ID
      const { data, error } = await supabase
        .from('products')
        .select('*')
        .eq('id', productId)
        .single();

      if (error) {
        console.error('Error fetching product:', error);
      } else {
        setProduct(data);
      }
    };

    fetchProduct();
  }, []);

  if (!product) {
    return <div>Loading...</div>;
  }

  const handleAddToCart = () => {
    // Inferred add-to-cart logic from video analysis
    console.log(`Adding ${product.name} (Color: ${selectedColor}, Size: ${selectedSize}) to cart`);
    // Implement actual cart logic here
  };

  return (
    <div>
      <img src={product.image_url} alt={product.name} />
      <h2>{product.name}</h2>
      <p>{product.description}</p>
      <p>Price: ${product.price}</p>

      <div>
        <h3>Color:</h3>
        {product.variants.map((variant) => (
          <button key={variant.color} onClick={() => setSelectedColor(variant.color)}>
            {variant.color}
          </button>
        ))}
      </div>

      <div>
        <h3>Size:</h3>
        {product.variants.map((variant) => (
          <button key={variant.size} onClick={() => setSelectedSize(variant.size)}>
            {variant.size}
          </button>
        ))}
      </div>

      <button onClick={handleAddToCart}>Add to Cart</button>
    </div>
  );
};

export default ProductPage;

This code snippet demonstrates how Replay infers data fetching (using Supabase in this example), state management (using

), and event handling (e.g., ) based on the video analysis. The is inferred based on the video; in a real-world scenario, Replay will attempt to parse this information from the URL or other visual cues.

Step 3: Reviewing and Refining the Generated Code#

Replay provides a visual editor where you can review the generated code and make necessary adjustments. You can:

• •Modify the code directly
• •Adjust the styling using CSS or a CSS-in-JS library
• •Fine-tune the data fetching logic
• •Add or remove UI elements

📝 Note: Replay's AI-powered engine learns from your feedback, continuously improving its accuracy and code generation capabilities.

Step 4: Integrating with Supabase#

Replay seamlessly integrates with Supabase, allowing you to easily connect your UI components to your database. The generated code often includes pre-configured data fetching logic, as shown in the previous code snippet.

⚠️ Warning: Ensure your Supabase credentials are properly configured and that your database schema matches the data structure inferred by Replay.

Step 5: Injecting Styles#

Replay allows you to inject styles into the generated component. You can use CSS, CSS-in-JS libraries (e.g., Styled Components, Emotion), or even Tailwind CSS. Replay analyzes the video to understand the visual styling and generates corresponding CSS rules.

css
/* Example generated CSS (simplified) */
.product-page {
  font-family: sans-serif;
  padding: 20px;
}

.product-image {
  max-width: 300px;
  margin-bottom: 20px;
}

.product-name {
  font-size: 24px;
  font-weight: bold;
  margin-bottom: 10px;
}

.product-description {
  margin-bottom: 10px;
}

.add-to-cart-button {
  background-color: #007bff;
  color: white;
  padding: 10px 20px;
  border: none;
  cursor: pointer;
}

Step 6: Product Flow Maps#

Replay can generate product flow maps based on the video analysis. These maps visually represent the user's journey through the e-commerce site, highlighting key interactions and transitions. This helps you understand user behavior and identify areas for improvement.

Step 7: Deploying Your Reconstructed Product Page#

Once you're satisfied with the generated code and styling, you can deploy your reconstructed product page to your web server or hosting platform.

Frequently Asked Questions#

Is Replay free to use?#

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

How is Replay different from v0.dev?#

While v0.dev generates code based on text prompts, Replay analyzes video recordings to understand user behavior and reconstruct UI components. Replay focuses on capturing the dynamic aspects of the user experience, while v0.dev is primarily focused on generating static UI elements. Replay excels at understanding the intent behind the UI, not just the visual appearance.

What type of videos work best with Replay?#

Clear, high-resolution videos with smooth transitions and minimal distractions work best. Ensure the video captures all relevant user interactions and UI elements.

Can Replay handle complex UI interactions?#

Yes, Replay's AI-powered engine is capable of handling complex UI interactions, such as form submissions, data validation, and dynamic content updates.

Does Replay support different UI frameworks?#

Currently, Replay primarily supports React. Support for other UI frameworks (e.g., Vue.js, Angular) is planned for future releases.
