Replay AI for Real Estate Applications: Building Dynamic Property Lists With Videos of UI

TL;DR: Replay AI reconstructs working real estate application UI from video recordings, enabling rapid prototyping and development of dynamic property listings.

Real estate application development is notoriously slow. Manually coding interactive property listings, search filters, and user interfaces can take weeks, even months. Existing screenshot-to-code tools often fall short because they only capture static visuals, missing crucial user interactions and dynamic behaviors. This leads to brittle code that requires significant rework.

Enter Replay AI, a revolutionary video-to-code engine powered by Gemini. Replay analyzes video recordings of existing UI to understand user behavior and reconstruct fully functional code. This "Behavior-Driven Reconstruction" approach allows developers to quickly generate dynamic property listings and interactive real estate application components directly from video demonstrations.

Understanding Behavior-Driven Reconstruction#

Traditional UI development often relies on static mockups or incomplete requirements. Developers spend considerable time interpreting these materials and translating them into working code. Replay flips this process by using video as the source of truth. By analyzing user interactions within the video, Replay understands what the user is trying to achieve, not just what they see.

This is crucial for real estate applications, where user interactions are complex and varied. Consider a user filtering properties by price range, location, and amenities. A screenshot-to-code tool might capture the visual appearance of the filter options, but it wouldn't understand the underlying logic of how these filters interact and update the property listings. Replay, on the other hand, analyzes the video to understand the user's intent and reconstructs the code accordingly.

Key Features for Real Estate App Development#

Replay offers several features that are particularly beneficial for building real estate applications:

• •Multi-Page Generation: Real estate applications often involve complex navigation between multiple pages, such as property listings, individual property details, user profiles, and search results. Replay can analyze videos that span multiple pages and generate code that accurately reflects the application's navigation structure.
• •Supabase Integration: Many modern real estate applications rely on cloud-based databases like Supabase to store property data, user information, and other relevant details. Replay seamlessly integrates with Supabase, allowing you to quickly connect your generated UI to your existing database.
• •Style Injection: Maintaining a consistent visual style across your application is crucial for branding and user experience. Replay allows you to inject custom CSS styles into the generated code, ensuring that your UI matches your desired aesthetic.
• •Product Flow Maps: Replay automatically generates product flow maps from the video analysis, providing a visual representation of the user's journey through the application. This helps developers understand the overall user experience and identify potential areas for improvement.

Building a Dynamic Property List with Replay: A Step-by-Step Guide#

Let's walk through the process of using Replay to build a dynamic property list for a real estate application.

Step 1: Record a Video of Your Desired UI#

The first step is to record a video of your desired UI. This could be a demo of an existing real estate application, a prototype you've created in a design tool, or even a hand-drawn mockup that you interact with on screen.

💡 Pro Tip: Ensure that the video is clear and well-lit, and that all user interactions are clearly visible.

Step 2: Upload the Video to Replay#

Once you have your video, upload it to Replay. Replay will automatically analyze the video and identify the different UI elements, user interactions, and application flow.

Step 3: Configure Supabase Integration#

If you're using Supabase to store your property data, you'll need to configure the Supabase integration in Replay. This involves providing your Supabase API URL and API key.

📝 Note: Make sure you have a Supabase project set up with a table containing your property data before proceeding.

Step 4: Customize the Generated Code#

After Replay has analyzed the video, it will generate a working code base. You can then customize the generated code to fine-tune the UI, add additional functionality, and integrate it with your existing application.

Here's an example of generated React code displaying a list of properties fetched from Supabase:

typescript
// Example React component generated by Replay
import { useEffect, useState } from 'react';
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;
const supabase = createClient(supabaseUrl, supabaseKey);

interface Property {
  id: number;
  address: string;
  price: number;
  bedrooms: number;
  bathrooms: number;
  image_url: string;
}

const PropertyList = () => {
  const [properties, setProperties] = useState<Property[]>([]);

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

      if (error) {
        console.error('Error fetching properties:', error);
      } else {
        setProperties(data as Property[]);
      }
    };

    fetchProperties();
  }, []);

  return (
    <div>
      {properties.map((property) => (
        <div key={property.id}>
          <img src={property.image_url} alt={property.address} />
          <h3>{property.address}</h3>
          <p>Price: ${property.price}</p>
          <p>{property.bedrooms} bedrooms, {property.bathrooms} bathrooms</p>
        </div>
      ))}
    </div>
  );
};

export default PropertyList;

This code snippet demonstrates how Replay can generate a React component that fetches property data from Supabase and displays it in a list. The component includes basic styling and displays key property details such as address, price, and number of bedrooms and bathrooms.

Step 5: Inject Custom Styles#

To ensure that the generated UI matches your desired aesthetic, you can inject custom CSS styles into the code. Replay provides a simple interface for adding custom CSS rules, which will be applied to the generated components.

For example, you might want to add the following CSS to style the property list:

css
.property-list {
  display: flex;
  flex-wrap: wrap;
  justify-content: space-around;
}

.property-item {
  width: 300px;
  margin-bottom: 20px;
  border: 1px solid #ccc;
  padding: 10px;
}

.property-item img {
  width: 100%;
  height: 200px;
  object-fit: cover;
}

⚠️ Warning: Always sanitize user inputs and validate data before displaying it in your UI to prevent security vulnerabilities.
