Building UI for Utilities: Managing Resources with AI

TL;DR: Learn how to leverage Replay and its behavior-driven reconstruction capabilities to build intuitive and efficient UIs for resource-intensive utility applications.

Building UI for Utilities: Managing Resources with AI#

The modern web demands interactive and responsive interfaces, especially when dealing with complex resource management in utility applications. Think dashboards monitoring energy consumption, tools for managing water usage, or platforms for tracking waste disposal. Traditionally, building these UIs has been a labor-intensive process. But what if you could simply show the desired behavior and have the code generated for you?

That's where Replay comes in. Replay leverages video analysis and AI to reconstruct working UIs from screen recordings, understanding user intent and generating clean, functional code. This approach, called Behavior-Driven Reconstruction, allows developers to rapidly prototype, iterate, and deploy complex UIs without the tedious manual coding.

The Challenge: Complex Resource Management UIs#

Building UIs for utility management presents unique challenges:

• •Data Visualization: Displaying real-time data streams from various sensors and sources requires robust charting and graphing components.
• •User Interaction: Allowing users to interact with the data, adjust settings, and trigger actions demands complex event handling and state management.
• •Responsiveness: Ensuring the UI remains responsive even under heavy data loads requires careful optimization and efficient rendering techniques.
• •Accessibility: Utility applications often serve diverse user groups, making accessibility a critical consideration.

Traditional screenshot-to-code tools fall short because they only capture the visual representation, not the behavior or intent. They can generate static HTML, but lack the dynamic functionality needed for a truly interactive utility UI.

Replay: Behavior-Driven Reconstruction in Action#

Replay takes a fundamentally different approach. By analyzing video recordings of user interactions, Replay understands the underlying behavior and reconstructs the UI accordingly. This means you can:

• •Demonstrate the desired functionality: Record yourself interacting with a prototype or existing UI.
• •Generate working code: Replay analyzes the video and generates clean, functional React (or other framework) code.
• •Customize and extend: The generated code is fully editable, allowing you to tailor it to your specific needs.

Here's a comparison of Replay versus other UI generation tools:

Building a Resource Monitoring Dashboard with Replay#

Let's walk through a simplified example of using Replay to build a resource monitoring dashboard for a smart home.

Step 1: Define the Desired Behavior

Imagine you want a dashboard that displays real-time energy consumption, water usage, and waste production. You envision users being able to:

• •View current readings for each resource.
• •See historical trends over time.
• •Set alerts when consumption exceeds a certain threshold.

Step 2: Record a Demonstration

Using a wireframe tool like Figma or even a hand-drawn sketch, create a basic visual representation of your desired dashboard. Then, record yourself interacting with it:

• •Clicking on different resource tabs.
• •Adjusting the date range for historical data.
• •Setting an alert threshold for energy consumption.

This video becomes the input for Replay.

Step 3: Generate the Code with Replay

Upload the video to Replay. Replay's AI engine will analyze the video, identify the UI elements, understand the user interactions, and generate the corresponding code.

Step 4: Customize and Integrate

Replay generates clean, well-structured code, ready for customization and integration into your existing project. Here's an example of the generated React code for displaying the energy consumption data:

typescript
// Generated by Replay - EnergyConsumption.tsx
import React, { useState, useEffect } from 'react';
import { LineChart, Line, XAxis, YAxis, CartesianGrid, Tooltip, Legend } from 'recharts';

interface EnergyData {
  time: string;
  consumption: number;
}

const EnergyConsumption = () => {
  const [data, setData] = useState<EnergyData[]>([]);

  useEffect(() => {
    // Fetch energy consumption data from API
    const fetchData = async () => {
      const response = await fetch('/api/energy');
      const jsonData = await response.json();
      setData(jsonData);
    };

    fetchData();
    const intervalId = setInterval(fetchData, 60000); // Update every minute

    return () => clearInterval(intervalId); // Cleanup interval on unmount
  }, []);

  return (
    <div>
      <h2>Energy Consumption</h2>
      <LineChart width={600} height={300} data={data}>
        <CartesianGrid strokeDasharray="3 3" />
        <XAxis dataKey="time" />
        <YAxis />
        <Tooltip />
        <Legend />
        <Line type="monotone" dataKey="consumption" stroke="#8884d8" activeDot={{ r: 8 }} />
      </LineChart>
    </div>
  );
};

export default EnergyConsumption;

💡 Pro Tip: Replay can automatically integrate with Supabase for data storage and retrieval, simplifying the backend development process. Simply configure your Supabase credentials and Replay will handle the data connection.

Step 5: Style Injection

Replay allows you to inject custom styles to match your existing design system. You can provide CSS or styled-components code snippets, and Replay will seamlessly integrate them into the generated UI. This ensures visual consistency and reduces the need for manual styling.

📝 Note: Replay's Product Flow maps visually represent the user's journey through the application, making it easier to understand the overall flow and identify potential usability issues.

Step 6: Multi-Page Generation

Replay supports multi-page applications. You can record separate videos for each page and Replay will generate the corresponding code, automatically handling navigation and state management.

Benefits of Using Replay for Utility UIs#

• •Rapid Prototyping: Quickly create functional prototypes by simply demonstrating the desired behavior.
• •Reduced Development Time: Automate the tedious task of manual coding, freeing up developers to focus on more complex tasks.
• •Improved User Experience: Ensure the UI accurately reflects the intended user experience by basing it on real-world interactions.
• •Enhanced Collaboration: Easily share prototypes and gather feedback by sharing the video recordings.
• •Lower Development Costs: Reduce the overall cost of development by automating the UI generation process.

⚠️ Warning: While Replay generates high-quality code, it's essential to review and test the generated code thoroughly to ensure it meets your specific requirements and security standards.

Example: Setting up an Alert#

Let's say you want to add functionality to set an alert when energy consumption exceeds a certain threshold. In your demonstration video, you would show the process of clicking on a settings icon, entering a threshold value, and saving the changes. Replay would then generate the code to handle this interaction, including:

typescript
// Example code generated by Replay for setting an alert
import React, { useState } from 'react';

const AlertSettings = () => {
  const [threshold, setThreshold] = useState<number>(100); // Default threshold

  const handleThresholdChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setThreshold(parseInt(event.target.value));
  };

  const handleSave = async () => {
    // Save the threshold to the backend
    await fetch('/api/alert', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ threshold }),
    });
    alert('Alert threshold saved!');
  };

  return (
    <div>
      <h2>Alert Settings</h2>
      <label>
        Threshold:
        <input type="number" value={threshold} onChange={handleThresholdChange} />
      </label>
      <button onClick={handleSave}>Save</button>
    </div>
  );
};

export default AlertSettings;

This code snippet showcases how Replay captures the user interaction (changing the threshold value) and generates the corresponding event handler (

) and API call ().
