Replay: Use AI to Build UI for Travel Booking Websites from Screen Recordings

TL;DR: Replay uses AI to analyze screen recordings of travel booking website interactions and generates functional, multi-page UI code, complete with Supabase integration and style injection.

Stop Manually Coding Travel Booking UIs: Let AI Do It#

Building user interfaces for travel booking websites is notoriously time-consuming. The complexity of managing flights, hotels, car rentals, and their associated search filters, date pickers, and payment gateways can quickly become overwhelming. What if you could simply show an AI what you want, and it would generate the code for you?

That's the promise of Replay. We're revolutionizing UI development by using video as the source of truth. Instead of relying on static screenshots or hand-waving descriptions, Replay analyzes behavior – the actual user interactions captured in a screen recording – to reconstruct working UI code.

The Problem with Traditional UI Development#

Traditional UI development for travel booking sites involves:

• •Designing wireframes and mockups: A necessary but time-consuming step.
• •Writing repetitive code: Implementing similar search filters, data displays, and booking flows across different service types (flights, hotels, etc.).
• •Integrating with APIs: Connecting to various travel provider APIs for real-time data.
• •Managing state: Handling complex state management for search queries, booking details, and user preferences.
• •Testing and debugging: Ensuring the UI works correctly across different browsers and devices.

This process is often slow, error-prone, and requires a significant investment of time and resources. Screenshot-to-code tools offer a partial solution, but they lack the crucial ability to understand user intent. They only see the final visual state, not the steps taken to get there.

Replay: Behavior-Driven Reconstruction#

Replay takes a different approach. By analyzing video recordings of user interactions, Replay understands what the user is trying to achieve, not just what they see on the screen. This "Behavior-Driven Reconstruction" allows Replay to generate more accurate, functional, and maintainable UI code.

Here's how Replay compares to other UI generation tools:

Replay is designed to bridge the gap between design and development, enabling you to rapidly prototype and iterate on your travel booking UI.

Building a Travel Booking UI with Replay: A Step-by-Step Guide#

Let's walk through the process of using Replay to generate UI code for a simple travel booking website. We'll focus on the flight search functionality.

Step 1: Record Your Interaction#

First, record a video of yourself interacting with an existing travel booking website. Focus on the core flight search flow:

1. •Navigate to the website.
2. •Enter your origin and destination cities.
3. •Select your travel dates.
4. •Specify the number of passengers.
5. •Initiate the search.
6. •Browse the search results.
7. •Select a flight.

The clearer and more deliberate your actions, the better Replay will understand your intent.

💡 Pro Tip: Speak aloud what you're doing as you record. This helps Replay's AI understand the context of your actions and generate more accurate code.

Step 2: Upload Your Video to Replay#

Once you have your recording, upload it to Replay. Replay's AI engine will begin analyzing the video, identifying UI elements, user interactions, and underlying data structures.

Step 3: Review and Refine the Generated Code#

After processing the video, Replay generates the UI code. You can then review and refine the code in Replay's editor. Replay supports various frontend frameworks, including React, Vue.js, and Angular.

Here's an example of the type of React code Replay might generate for a flight search form:

typescript
// FlightSearchForm.tsx
import React, { useState } from 'react';

interface FlightSearchFormProps {
  onSearch: (origin: string, destination: string, date: Date) => void;
}

const FlightSearchForm: React.FC<FlightSearchFormProps> = ({ onSearch }) => {
  const [origin, setOrigin] = useState('');
  const [destination, setDestination] = useState('');
  const [date, setDate] = useState<Date>(new Date());

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    onSearch(origin, destination, date);
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="origin">Origin:</label>
        <input
          type="text"
          id="origin"
          value={origin}
          onChange={(e) => setOrigin(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="destination">Destination:</label>
        <input
          type="text"
          id="destination"
          value={destination}
          onChange={(e) => setDestination(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="date">Date:</label>
        <input
          type="date"
          id="date"
          value={date.toISOString().slice(0, 10)}
          onChange={(e) => setDate(new Date(e.target.value))}
        />
      </div>
      <button type="submit">Search Flights</button>
    </form>
  );
};

export default FlightSearchForm;

This code includes:

• •State management for the origin, destination, and date.
• •Input fields for users to enter their search criteria.
• •A submit handler to trigger the flight search.

Replay can also generate the associated CSS or styling based on the visual elements in the video.

Step 4: Integrate with Your Backend#

Replay allows seamless integration with backend services, including Supabase. You can configure Replay to automatically generate API calls to your Supabase database based on the user interactions in the video.

For example, if the video shows you submitting a flight search form, Replay can generate the necessary API call to query your Supabase database for matching flights.

📝 Note: Replay's Supabase integration simplifies data fetching and persistence, allowing you to focus on building the UI and user experience.

Step 5: Style Injection and Customization#

Replay supports style injection, allowing you to apply custom styles to the generated UI. You can use CSS, Tailwind CSS, or any other styling library to customize the appearance of your travel booking website.

⚠️ Warning: While Replay generates functional code, you may need to adjust the styling to match your specific design requirements.

Step 6: Multi-Page Generation and Product Flow Maps#

One of Replay's key features is its ability to generate multi-page UIs. By analyzing the video, Replay can identify the different pages and states involved in the travel booking flow. This allows Replay to generate code for the entire booking process, from searching for flights to confirming the booking.

Replay also generates Product Flow maps that visually represent the user journey through the application. This helps you understand the flow of the application and identify potential areas for improvement.
