How to Reconstruct a Complete Financial Dashboard from Video to Code with Replay

TL;DR: Reconstruct a fully functional financial dashboard from a simple screen recording using Replay's behavior-driven code generation, complete with Supabase integration and dynamic styling.

The Challenge: From Pixel to Productive Financial Dashboard#

Creating a financial dashboard from scratch is a time-consuming process. Traditional approaches involve countless hours of design, coding, and integration. What if you could bypass the manual labor and generate a functional dashboard directly from a video recording of its intended use? That's the power of behavior-driven reconstruction.

The problem with traditional screenshot-to-code tools is that they only capture the visual representation. They lack the crucial understanding of user intent and dynamic behavior. A static image of a chart doesn't tell you how the data is fetched, filtered, or updated. This is where Replay steps in.

Replay: Bridging the Gap Between Vision and Reality#

Replay analyzes video recordings to understand user behavior, workflows, and interactions. By leveraging Gemini, Replay reconstructs the UI, including the underlying code and logic, enabling you to create functional applications from video demonstrations. This approach, which we call "Behavior-Driven Reconstruction," treats the video as the source of truth.

Reconstructing a Financial Dashboard: Step-by-Step#

Let's walk through reconstructing a financial dashboard from a video recording using Replay. This example will include data visualization, real-time updates, and user interaction.

Step 1: Capturing the Video#

The first step is to create a clear and comprehensive video recording of the desired dashboard functionality. This recording should showcase:

• •Data sources (e.g., stock prices, transaction history)
• •Chart types (e.g., line charts, bar graphs, pie charts)
• •User interactions (e.g., filtering data, zooming in on charts)
• •Dynamic updates (e.g., real-time stock price changes)
• •Overall dashboard layout and navigation

💡 Pro Tip: Ensure the video is well-lit and the UI elements are clearly visible. Speak clearly about your actions in the video to help Replay better understand your intent.

Step 2: Uploading to Replay#

Once you have the video, upload it to the Replay platform. Replay will then analyze the video, identify UI elements, and understand the relationships between them.

Step 3: Code Generation and Review#

Replay generates clean, well-structured code based on the video analysis. This code includes:

• •UI components (e.g., charts, tables, input fields)
• •Data fetching logic (e.g., API calls, database queries)
• •Event handlers (e.g., button clicks, form submissions)
• •Styling (e.g., CSS, Tailwind)

You can review the generated code and make any necessary adjustments. Replay provides a visual editor that allows you to modify the UI and code simultaneously.

Step 4: Supabase Integration#

A key feature of Replay is its seamless integration with Supabase. This allows you to easily connect your dashboard to a real-time database.

1. •

   Define your Supabase schema: Create the necessary tables and columns to store your financial data (e.g., stock prices, transaction history).

2. •

   Configure Replay: Provide your Supabase API URL and API key to Replay.

3. •

   Data Binding: Replay automatically binds the UI components to the Supabase data. Any changes in the database will be reflected in the dashboard in real-time.

Here's an example of how Replay might generate code to fetch stock prices from Supabase:

typescript
// Fetch stock prices from Supabase
const fetchStockPrices = async (symbol: string) => {
  const { data, error } = await supabase
    .from('stock_prices')
    .select('*')
    .eq('symbol', symbol)
    .order('timestamp', { ascending: false });

  if (error) {
    console.error('Error fetching stock prices:', error);
    return [];
  }

  return data;
};

// Example usage:
const stockPrices = await fetchStockPrices('AAPL');
console.log(stockPrices);

Step 5: Style Injection#

Replay allows you to inject custom styles into your dashboard, ensuring it aligns with your brand and design preferences. You can use CSS, Tailwind CSS, or any other styling framework.

For example, to change the background color of the dashboard to a dark theme, you can add the following CSS:

css
body {
  background-color: #121212;
  color: #ffffff;
}

.card {
  background-color: #1e1e1e;
  border: 1px solid #333333;
}

Replay will automatically apply these styles to the generated code.

Step 6: Product Flow Maps#

Replay generates product flow maps to visualize the user journey through your dashboard. This helps you understand how users interact with the different components and identify areas for improvement.

The product flow map shows the sequence of user actions, the corresponding UI changes, and the underlying code execution. This provides a comprehensive overview of the dashboard's functionality.

⚠️ Warning: While Replay automates much of the process, it's crucial to review the generated code and ensure it meets your specific requirements. Pay close attention to data validation, error handling, and security considerations.

Benefits of Using Replay for Dashboard Reconstruction#

• •Faster Development: Generate a functional dashboard in minutes instead of days.
• •Reduced Costs: Minimize manual coding effort and reduce development costs.
• •Improved Accuracy: Reconstruct the dashboard based on actual user behavior, ensuring it meets user needs.
• •Enhanced Collaboration: Share video recordings and generated code with your team for seamless collaboration.
• •Real-time Updates: Integrate with Supabase for real-time data updates and dynamic dashboards.

Replay vs. Other Code Generation Tools#

📝 Note: Replay is continuously evolving, with new features and improvements being added regularly. Check the Replay documentation for the latest updates.

Code Example: Real-time Stock Chart#

Here's an example of how Replay can generate code for a real-time stock chart using a library like Chart.js, integrated with Supabase for live data:

javascript
import { Chart, registerables } from 'chart.js';
Chart.register(...registerables);

const ctx = document.getElementById('stockChart').getContext('2d');

const chart = new Chart(ctx, {
  type: 'line',
  data: {
    labels: [], // Timestamp labels
    datasets: [{
      label: 'Stock Price',
      data: [], // Stock price data
      borderColor: 'rgb(75, 192, 192)',
      tension: 0.1
    }]
  },
  options: {}
});

// Subscribe to Supabase for real-time updates
supabase
  .channel('stock_prices')
  .on('postgres_changes', { event: '*', schema: 'public', table: 'stock_prices' }, payload => {
    const newPrice = payload.new;
    chart.data.labels.push(newPrice.timestamp);
    chart.data.datasets[0].data.push(newPrice.price);
    chart.update();
  })
  .subscribe()

This code snippet demonstrates how Replay can generate the necessary code to create a dynamic, real-time stock chart using Supabase for data updates.

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. Check the Replay pricing page for details.

How is Replay different from v0.dev?#

While both Replay and v0.dev aim to accelerate UI development, they differ in their approach. v0.dev uses AI to generate code based on text prompts, whereas Replay uses video analysis to understand user behavior and reconstruct the UI accordingly. Replay focuses on understanding how the UI is used, not just what it looks like.

What types of applications can I reconstruct with Replay?#

Replay can be used to reconstruct a wide range of applications, including dashboards, e-commerce sites, mobile apps, and web applications. The key requirement is a clear video recording of the desired functionality.

What if Replay doesn't generate the exact code I need?#

Replay provides a visual editor that allows you to modify the generated code and UI. You can also add custom code and integrate with other tools and libraries.

What kind of video quality is required for Replay to work effectively?#

While Replay can handle a range of video qualities, a clear, well-lit video with visible UI elements will produce the best results. Avoid blurry or shaky videos.
