Generating UI for Pollution Control: Reducing Air and Water Pollution

TL;DR: Replay uses video analysis to generate functional UI code for pollution control applications, offering a faster, more accurate alternative to screenshot-based and AI-assisted code generation.

The fight against pollution demands efficient, intuitive user interfaces for monitoring, analysis, and control. But building these UIs from scratch is time-consuming and requires specialized expertise. Existing low-code/no-code solutions often lack the flexibility needed for complex pollution management scenarios. Screenshot-to-code tools fall short because they can't capture the behavior behind the UI.

Replay offers a revolutionary approach: behavior-driven code generation from video. Imagine recording a product flow of interacting with a pollution monitoring dashboard. Replay analyzes that video, understands the user's intent, and generates working code that replicates that functionality. No more tedious manual coding or wrestling with inflexible templates.

The Problem: Manual UI Development for Pollution Control#

Developing effective UIs for pollution control presents several challenges:

• •Data Visualization Complexity: Pollution data is often multi-faceted, requiring sophisticated charts, maps, and dashboards. Manually coding these visualizations is complex and error-prone.
• •Real-Time Data Integration: Pollution monitoring systems often require real-time data feeds from sensors and databases. Integrating these feeds into a UI requires significant coding effort.
• •Regulatory Compliance: Pollution control UIs must often adhere to strict regulatory requirements. Ensuring compliance through manual coding is a challenging task.
• •Specialized Knowledge: Developers need to understand not only UI development but also the intricacies of pollution monitoring and control. This combination of skills is rare and expensive.

Replay: Behavior-Driven UI Generation from Video#

Replay tackles these challenges head-on by leveraging video analysis and AI to generate functional UI code. Instead of relying on static screenshots or limited AI-assisted tools, Replay analyzes the behavior captured in a video recording to understand the user's intent and generate code that accurately replicates that functionality.

How Replay Works: A Step-by-Step Overview#

1. •Record the UI Interaction: Record a video of yourself interacting with an existing pollution monitoring dashboard or a mockup of the desired UI. This video captures the desired user flow and functionality.
2. •Upload to Replay: Upload the video to the Replay platform.
3. •AI-Powered Analysis: Replay's AI engine analyzes the video, identifying UI elements, user actions, and data flows.
4. •Code Generation: Replay generates clean, functional code in your preferred framework (React, Vue, Angular, etc.).
5. •Customization and Integration: Customize the generated code and integrate it into your existing pollution control systems.

Key Features of Replay#

• •Multi-Page Generation: Replay can generate code for complex, multi-page UIs, capturing entire user flows across different screens.
• •Supabase Integration: Seamlessly integrate your generated UI with Supabase for data storage, authentication, and real-time updates.
• •Style Injection: Customize the look and feel of your UI by injecting custom CSS styles.
• •Product Flow Maps: Visualize the user flow captured in the video, providing a clear understanding of the generated UI's functionality.

💡 Pro Tip: When recording your video for Replay, focus on clear, deliberate interactions. This will help Replay accurately capture the user's intent.

Generating a Pollution Monitoring Dashboard with Replay: A Tutorial#

Let's walk through a simplified example of using Replay to generate a UI for a pollution monitoring dashboard.

Step 1: Design a Mockup (Optional)#

While not strictly required, creating a simple mockup of your desired dashboard can help guide the video recording process. You can use tools like Figma or even a hand-drawn sketch. The key elements for our example are:

• •A map displaying pollution levels in different areas.
• •A chart showing historical pollution data.
• •A set of controls for filtering and analyzing the data.

Step 2: Record the Video#

Record a video of yourself interacting with the mockup (or an existing similar dashboard). Clearly demonstrate the desired user flow:

1. •Zoom in and out on the map to view pollution levels in different regions.
2. •Select different pollution types (e.g., PM2.5, Ozone) using dropdown menus.
3. •Adjust the date range to view historical data.
4. •Click on specific data points in the chart to view detailed information.

📝 Note: Ensure the video is clear and well-lit. Speak clearly to narrate your actions, further aiding Replay's analysis.

Step 3: Upload to Replay and Generate Code#

1. •Upload the recorded video to the Replay platform.
2. •Select your desired output framework (e.g., React).
3. •Click "Generate Code."

Replay will analyze the video and generate the corresponding code. This process typically takes a few minutes.

Step 4: Customize and Integrate#

The generated code will provide a functional UI skeleton. You'll likely need to customize it to integrate with your specific data sources and backend systems.

Here's an example of generated React code for displaying pollution data in a chart:

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

interface PollutionData {
  date: string;
  pm25: number;
  ozone: number;
}

const PollutionChart: React.FC = () => {
  const [data, setData] = useState<PollutionData[]>([]);

  useEffect(() => {
    // Replace with your actual data fetching logic
    const fetchData = async () => {
      const response = await fetch('/api/pollution-data');
      const jsonData = await response.json();
      setData(jsonData);
    };

    fetchData();
  }, []);

  return (
    <LineChart width={730} height={250} data={data}
      margin={{ top: 5, right: 30, left: 20, bottom: 5 }}>
      <CartesianGrid strokeDasharray="3 3" />
      <XAxis dataKey="date" />
      <YAxis />
      <Tooltip />
      <Legend />
      <Line type="monotone" dataKey="pm25" stroke="#8884d8" />
      <Line type="monotone" dataKey="ozone" stroke="#82ca9d" />
    </LineChart>
  );
};

export default PollutionChart;

This code provides a basic chart component. You'll need to:

• •Replace the placeholder
  text

  /api/pollution-data
  endpoint with your actual API endpoint.
• •Adjust the data keys (
  text

  pm25
  ,
  text

  ozone
  ,
  text

  date
  ) to match your data format.
• •Customize the chart appearance and styling as desired.

Here's an example of how you might integrate the generated UI with Supabase for real-time data updates:

typescript
// Assuming you have a Supabase client initialized
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

useEffect(() => {
  const subscription = supabase
    .from('pollution_data')
    .on('*', (payload) => {
      // Update the chart data based on the payload
      console.log('Change received!', payload);
      // Implement logic to update the 'data' state with the new data
    })
    .subscribe();

  return () => supabase.removeSubscription(subscription);
}, []);

This code subscribes to changes in the

table in your Supabase database. Whenever new data is inserted, updated, or deleted, the callback will be triggered, allowing you to update the UI in real-time.

⚠️ Warning: Remember to replace

text

YOUR_SUPABASE_URL

and

text

YOUR_SUPABASE_ANON_KEY

with your actual Supabase credentials.
