How to Recreate a Modern E-Commerce Website from Video to React Using Replay AI

TL;DR: Replay AI lets you reconstruct a fully functional React-based e-commerce website directly from a screen recording, leveraging behavior-driven reconstruction for accurate UI and logic generation.

From Video to React: Recreating an E-Commerce Site with Replay AI#

Building e-commerce websites can be a time-consuming process, often involving repetitive coding and UI design tasks. What if you could bypass much of the manual work and generate a fully functional React-based e-commerce site simply by recording a video of the desired user flow? This is the power of Replay.

Replay leverages advanced video analysis and AI to understand user behavior and intent, translating your screen recordings into clean, efficient, and working code. Unlike traditional screenshot-to-code tools that merely replicate visual elements, Replay uses "Behavior-Driven Reconstruction" to capture the underlying logic and interactions, resulting in a more robust and maintainable codebase.

This article will guide you through the process of recreating a modern e-commerce website from video to React using Replay AI, showcasing its key features and practical implementation.

Understanding Behavior-Driven Reconstruction#

The core innovation behind Replay lies in its "Behavior-Driven Reconstruction" approach. Instead of just recognizing visual elements in a video, Replay analyzes the actions performed within the recording. It understands clicks, scrolls, form submissions, and other user interactions, enabling it to infer the underlying functionality and data flow.

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

• •Accurate Logic Capture: Replay doesn't just recreate the UI; it reconstructs the logic behind it. This means that the generated code is not just a static representation but a functional application.
• •Improved Maintainability: The code generated by Replay is typically cleaner and more organized than code produced by simple visual recognition tools. This makes it easier to maintain and extend the application in the future.
• •Reduced Manual Coding: By automating the reconstruction of both UI and logic, Replay significantly reduces the amount of manual coding required to build an e-commerce website.

Replay AI: Key Features#

Replay comes packed with features tailored for efficient and accurate code generation:

• •Multi-Page Generation: Replay can analyze videos that span multiple pages or views within an application, generating code for the entire flow.
• •Supabase Integration: Seamlessly integrate your generated e-commerce site with Supabase for backend functionality, including database management and authentication.
• •Style Injection: Easily apply custom styles to your generated components, ensuring that the final product matches your desired aesthetic.
• •Product Flow Maps: Visualize the user flow within your recorded video, providing a clear overview of the application's structure and functionality.

Setting Up Your E-Commerce Project with Replay#

Let's walk through the process of recreating a basic e-commerce website, focusing on a product listing and a simple checkout flow. We'll assume you have a video recording of the desired user experience.

Step 1: Recording Your Video#

The first step is to record a video of the e-commerce website's user flow. This should include:

1. •Navigating to the product listing page.
2. •Selecting a product.
3. •Adding the product to the cart.
4. •Proceeding to checkout.
5. •Entering shipping information.

💡 Pro Tip: Keep the video concise and focused. Avoid unnecessary actions or distractions to ensure the best results from Replay.

Step 2: Uploading and Processing the Video#

1. •Navigate to the Replay platform (https://replay.build).
2. •Create an account or log in.
3. •Upload your video recording.
4. •Replay will begin processing the video, analyzing the user behavior and identifying the UI elements.

Step 3: Reviewing and Refining the Generated Code#

Once Replay has finished processing the video, you'll be presented with a code preview. This allows you to review the generated React components and make any necessary adjustments.

📝 Note: Replay's AI is constantly improving, but it's always a good idea to review the generated code and ensure it meets your specific requirements.

Step 4: Integrating with Supabase#

To add backend functionality to your e-commerce website, you can integrate it with Supabase. Replay provides seamless integration with Supabase, allowing you to easily manage your product data, user authentication, and order processing.

1. •Create a Supabase project.
2. •Configure the Supabase integration within Replay.
3. •Replay will automatically generate the necessary code to interact with your Supabase database.

Step 5: Customizing Styles#

Replay allows you to inject custom styles into your generated components. This ensures that the final product matches your desired aesthetic. You can use CSS, Sass, or any other styling framework.

1. •Define your custom styles.
2. •Inject the styles into the Replay platform.
3. •Replay will apply the styles to the generated components.

Code Examples and Implementation Details#

Here are some code snippets illustrating how Replay handles specific aspects of e-commerce website reconstruction:

Product Listing Component#

typescript
// Generated by Replay
import React, { useState, useEffect } from 'react';
import { supabase } from './supabaseClient'; // Assuming you have a supabaseClient.js

interface Product {
  id: number;
  name: string;
  description: string;
  price: number;
  image_url: string;
}

const ProductList: React.FC = () => {
  const [products, setProducts] = useState<Product[]>([]);

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

      if (error) {
        console.error('Error fetching products:', error);
      } else {
        setProducts(data || []);
      }
    };

    fetchProducts();
  }, []);

  return (
    <div className="product-list">
      {products.map(product => (
        <div key={product.id} className="product-card">
          <img src={product.image_url} alt={product.name} />
          <h3>{product.name}</h3>
          <p>{product.description}</p>
          <p>${product.price}</p>
          <button>Add to Cart</button>
        </div>
      ))}
    </div>
  );
};

export default ProductList;

This code demonstrates how Replay can automatically generate a product listing component that fetches data from a Supabase database.

Add to Cart Functionality#

typescript
// Example Add to Cart function
const addToCart = async (productId: number) => {
  // Assuming you have a user authentication system with Supabase
  const { data: { user } } = await supabase.auth.getUser();

  if (!user) {
    alert("Please log in to add items to your cart.");
    return;
  }

  const { data, error } = await supabase
    .from('cart_items')
    .insert([
      { user_id: user.id, product_id: productId, quantity: 1 }
    ]);

  if (error) {
    console.error("Error adding to cart:", error);
  } else {
    alert("Added to cart!");
  }
};

// Integrate this function into the ProductList component
// Inside the product-card div:
// <button onClick={() => addToCart(product.id)}>Add to Cart</button>

This code shows how Replay can infer the "Add to Cart" functionality and generate the necessary code to interact with the Supabase database.
