frontend/src/app/locate/page.tsx (2)
57-96: Robust CSV Export Implementation
The CSV export logic is well thought out—using a Set to avoid duplicates and generating a download via Blob. An optional enhancement might be to add error handling around Blob creation for maximum robustness.
98-112: Map Screenshot Feature Implementation
Employinghtml2canvasto snapshot the map element is an effective solution for saving images. Consider adding a catch block to handle potential errors from the asynchronous canvas generation.frontend/src/hooks/use-api.tsx (1)
42-48: Consider adding a more targeted reset function.The reset function is useful, but consider expanding its capabilities to allow partial resets.
- reset: useCallback(() => { - setState({ data: null, isLoading: false, error: null }) - }, []), + reset: useCallback((options?: { keepData?: boolean }) => { + setState(prev => ({ + data: options?.keepData ? prev.data : null, + isLoading: false, + error: null + })) + }, []),This would allow components to reset error states while optionally preserving data, which can improve user experience during form submissions.
frontend/src/components/error-boundary.tsx (1)
1-60: Good implementation of error boundary pattern.This new error boundary component follows React best practices by properly implementing the error lifecycle methods. The fallback UI provides users with clear recovery options.
Consider sanitizing error messages in production to avoid potentially exposing sensitive information:
-<p className="text-gray-600 mb-6 max-w-md">{this.state.error?.message || "An unexpected error occurred"}</p> +<p className="text-gray-600 mb-6 max-w-md"> + {process.env.NODE_ENV === 'production' + ? "An unexpected error occurred" + : (this.state.error?.message || "An unexpected error occurred")} +</p>frontend/src/components/map/MapComponent.tsx (2)
14-18: Duplicate global interface declaration found.There are two identical global interface declarations for
Windowin this file. This redundancy could lead to confusion and should be consolidated.// Keep this one at the top declare global { interface Window { map?: L.Map } } // Remove this duplicate declaration -declare global { - interface Window { - map: L.Map - } -}Also applies to: 59-63
21-21: Performance: Avoid using delete operator.The delete operator can impact performance. Consider using undefined assignment instead.

Heads Up: Verify Image Asset Paths
The recent update in "frontend/src/components/map/LeafletMap.tsx" replaces the @public alias with direct image paths. However, the verification script flagged that none of the images were found. This appears to stem from the script aggregating multiple "public" directories in the monorepo rather than targeting the specific folder used by the frontend app.
- Confirm that the image assets are placed in the correct directory for your frontend application (for example, ensure they exist under
frontend/public/images/). - Double-check that your deployment/build configuration correctly resolves the absolute paths (e.g.,
/images/GoodAir.pngshould point to the intended location within your app's public folder). - Adjust the image paths and/or update the asset serving configuration as needed to prevent potential loading issues in production.

40-51: Consider enhancing image accessibility and error handling.The image error handling is good, but you might want to consider adding more descriptive alt text and improving the fallback image strategy.
<Image src="/images/health-impact.jpg" - alt="Health impact assessment visualization" + alt="Visualization showing health impact assessment data with population health metrics across different regions" fill className="object-cover" onError={(e) => { // Fallback if image doesn't exist - e.currentTarget.src = "/placeholder.svg?height=400&width=600" + e.currentTarget.src = "/placeholders/health-impact-placeholder.svg" + // Consider also logging this error to your monitoring system }} />
16-19: Consider enhancing back button accessibility.The back button could benefit from additional accessibility attributes.
<Link href="/" className="inline-flex items-center text-blue-600 hover:text-blue-800 mb-8" + aria-label="Navigate back to home page" > <ChevronLeft className="h-4 w-4 mr-1" /> Back to Home </Link>frontend/src/app/features/air-quality-categorization/page.tsx (1)
40-51: Consider improving image error handling logic.The current fallback uses a generic placeholder. Consider creating feature-specific placeholders for better user experience.
<Image src="/images/air-quality-categorization.jpg" alt="Air quality categorization visualization" fill className="object-cover" onError={(e) => { // Fallback if image doesn't exist - e.currentTarget.src = "/placeholder.svg?height=400&width=600" + e.currentTarget.src = "/placeholders/categorization-placeholder.svg" }} />frontend/src/app/features/interactive-mapping/page.tsx (1)
89-138: Consider making icons more contextually relevant.All four benefits use the same MapPin icon. Consider using different icons that better represent each specific benefit for improved visual distinction.
<!-- For the first benefit, keep the MapPin --> <MapPin className="h-6 w-6 text-blue-600" /> <!-- For Hotspot Identification (around line 104) --> -<MapPin className="h-6 w-6 text-blue-600" /> +<AlertCircle className="h-6 w-6 text-blue-600" /> <!-- For Location Search (around line 116) --> -<MapPin className="h-6 w-6 text-blue-600" /> +<Search className="h-6 w-6 text-blue-600" /> <!-- For Multiple Map Layers (around line 128) --> -<MapPin className="h-6 w-6 text-blue-600" /> +<Layers className="h-6 w-6 text-blue-600" />This would require adding the new icons to your imports at the top:

1-159: Consider refactoring feature pages to reduce duplication.I've noticed that all feature pages follow nearly identical patterns. Consider creating a reusable FeaturePageTemplate component to reduce code duplication and improve maintainability.
This would involve:
- Creating a new component with props for title, description, image, steps, benefits, etc.
- Refactoring each feature page to use this template with its specific content
This approach would significantly reduce code duplication and make future updates easier to implement across all feature pages.

87-138: Consider using distinct icons for each benefit to improve visual communication.Currently, all four benefits in the "Key Benefits" section use the same MapPin icon. Using distinct icons that better represent each benefit (e.g., a coverage icon for "Maximize Coverage", a coin/money icon for "Cost Efficiency", etc.) would improve visual differentiation and enhance user understanding.

9-151: Significant structural duplication with SiteLocationFeature.This component shares almost identical structure with SiteLocationFeature, differing only in content. This pattern indicates an opportunity to create a reusable FeaturePage component that accepts content props. Doing so would:
- Reduce code duplication
- Improve maintainability
- Ensure consistent styling across feature pages
- Make creating new feature pages faster and less error-prone
Consider creating a generic template that both components could use.

70-91: Consider using semantic list markup for better accessibilityThe list is currently implemented using custom styled
divandspanelements. While visually effective, this approach lacks the semantic meaning that proper list elements provide.Consider replacing the current implementation with proper
ul/lielements while maintaining the styling:- <ul className="space-y-3 mb-6"> - <li className="flex items-start"> - <span className="text-blue-500 mr-2 font-bold">•</span> - <span>Population density and distribution patterns</span> - </li> + <ul className="space-y-3 mb-6 list-none"> + <li className="flex items-start"> + <span className="text-blue-500 mr-2 font-bold" aria-hidden="true">•</span> + <span>Population density and distribution patterns</span> + </li>Adding
list-noneremoves default bullets whilearia-hidden="true"on the bullet character prevents screen readers from announcing it.
32-44: Button component inside Link needs hover state handlingThe Button component wrapped inside a Link component might have conflicting hover states, and the Link's default accessibility attributes need to be preserved.
Consider updating the Button implementation inside the Link component:
<Link href="/locate"> - <Button className="bg-blue-600 hover:bg-blue-700 text-white px-6 py-3 rounded-lg font-medium inline-flex items-center"> + <Button className="bg-blue-600 hover:bg-blue-700 text-white px-6 py-3 rounded-lg font-medium inline-flex items-center w-full" asChild> Try Site Locator <ArrowRight className="ml-2 h-5 w-5" /> </Button> </Link>If your Button component supports the
asChildpattern, this will merge the Button's props with the Link component for better accessibility and consistent hover states.
1-8: Consider organizing imports by categoryWhile not a functional issue, organizing imports can improve code readability and maintainability.
Consider grouping imports by category:
"use client" - import Link from "next/link" - import Image from "next/image" - import { ArrowRight, MapPin, ChevronLeft } from "lucide-react" - import Navigation from "@/components/navigation/navigation" - import { Button } from "@/ui/button" + // Next.js imports + import Link from "next/link" + import Image from "next/image" + + // UI components + import Navigation from "@/components/navigation/navigation" + import { Button } from "@/ui/button" + + // Icons + import { ArrowRight, MapPin, ChevronLeft } from "lucide-react"frontend/src/app/page.tsx (3)
59-59: Ensure Image component has proper error handlingUnlike the site-location page, this Image component doesn't have an error fallback mechanism.
Consider adding error handling similar to what you implemented in the site-location page:
- <Image src="/images/homeMAP.png" alt="Air quality monitoring dashboard" fill className="object-cover" /> + <Image + src="/images/homeMAP.png" + alt="Air quality monitoring dashboard" + fill + className="object-cover" + onError={(e) => { + // Fallback if image doesn't exist + e.currentTarget.src = "/placeholder.svg?height=500&width=900" + }} + />
5-17: Consider using named imports for better readabilityThe import statement for Lucide icons is getting quite long, which can make it hard to track which icons are actually used in the file.
For large import lists, consider using named imports with explicit renaming when necessary:
- import { - ArrowRight, - MapPin, - Wind, - BarChart3, - BrainCircuit, - Shield, - Sliders, - LineChart, - Zap, - Satellite, - Factory, - } from "lucide-react" + // Navigation icons + import { ArrowRight, ChevronLeft } from "lucide-react" + // Data visualization icons + import { BarChart3, LineChart } from "lucide-react" + // Technology icons + import { BrainCircuit, Sliders, Zap } from "lucide-react" + // Location and environment icons + import { MapPin, Wind, Satellite, Factory, Shield } from "lucide-react"This approach makes it easier to understand the purpose of each imported icon and helps with future maintenance.
115-115: Implement consistent Button usage patternsThe Link-Button pattern is implemented differently in different places. In some places, the Button is inside the Link (like here), while in the features section you're using the Link wrapping a custom card component.
For consistency, consider standardizing how Link and Button components interact:
<Link href="/reports"> - <Button className="w-full bg-blue-600 hover:bg-blue-700">Explore Forecasting</Button> + <Button className="w-full bg-blue-600 hover:bg-blue-700" asChild> + <span>Explore Forecasting</span> + </Button> </Link>If your Button component supports the
asChildpattern from Radix UI, this approach will provide better accessibility and consistent hover states.Also applies to: 152-153, 189-190, 226-227, 263-264

🛠️ Refactor suggestion
Enhance accessibility of clickable divs
The FeatureCard component is now clickable since it's wrapped in a Link, but the div itself has a cursor-pointer class which might mislead users about where the clickable area is.
Since the entire card is now clickable via the wrapping Link component, enhance the accessibility properties:
- <div className="bg-white p-6 rounded-xl border border-gray-100 shadow-sm hover:shadow-md transition-shadow cursor-pointer h-full">
+ <div className="bg-white p-6 rounded-xl border border-gray-100 shadow-sm hover:shadow-md transition-shadow h-full">This removes the redundant cursor-pointer style since the Link component will already provide appropriate cursor styling. The Link wrapping already makes the entire component clickable, so explicit cursor styling on the inner div is unnecessary.

Review double-click navigation behavior
You've implemented a double-click handler that navigates to the map page, but this creates multiple ways to navigate to the same page which may confuse users.
Consider if this double-click handler is necessary:
If there are already accessible navigation options to the map page, you might want to remove this double-click handler for consistency and to avoid unexpected navigation.

Double-click Navigation Redundancy
The double-click handler on line 57 of frontend/src/app/page.tsx performs a navigation to the /map page. However, the codebase already contains multiple conventional navigation options (via <Link href="/map"> and regular anchor tags) across various files, including multiple instances in frontend/src/app/page.tsx, frontend/src/app/ai-technologies/page.tsx, and frontend/src/app/features/interactive-mapping/page.tsx.

You could extract sections like "CoreAITechnologies", "TechnicalApproach", "AdditionalAIApplications", etc., into separate components. This would make the main component more readable and facilitate reuse across the application.
Example refactoring for the Core AI Technologies section:
- {/* Core AI Technologies Section */} - <div className="mb-20"> - <h2 className="text-3xl font-bold mb-10 text-center">Our Core AI Technologies</h2> - <div className="grid md:grid-cols-3 gap-10"> - {/* Forecasting AI */} - <div className="bg-white rounded-xl shadow-md overflow-hidden transition-transform hover:scale-105"> - {/* ... */} - </div> - {/* Calibration AI */} - <div className="bg-white rounded-xl shadow-md overflow-hidden transition-transform hover:scale-105"> - {/* ... */} - </div> - {/* Location AI */} - <div className="bg-white rounded-xl shadow-md overflow-hidden transition-transform hover:scale-105"> - {/* ... */} - </div> - </div> - </div> + <CoreAITechnologies />
15-18: Enhance accessibility of back navigation linkThe back button link could benefit from additional accessibility attributes.
Consider adding an
aria-labelto provide more context for screen readers:- <Link href="/" className="inline-flex items-center text-blue-600 hover:text-blue-800 mb-8"> + <Link href="/" className="inline-flex items-center text-blue-600 hover:text-blue-800 mb-8" aria-label="Navigate back to home page"> <ChevronLeft className="h-4 w-4 mr-1" /> Back to Home </Link>
39-73: Extract repetitive card components to reduce duplicationThe three technology cards (Forecasting AI, Calibration AI, and Location AI) share very similar structure with only content differences.
Consider extracting a reusable
TechnologyCardcomponent to reduce duplication:type TechnologyCardProps = { title: string; description: string; features: string[]; icon: React.ReactNode; color: string; linkHref: string; linkText: string; }; const TechnologyCard = ({ title, description, features, icon, color, linkHref, linkText }: TechnologyCardProps) => ( <div className="bg-white rounded-xl shadow-md overflow-hidden transition-transform hover:scale-105"> <div className={`relative h-48 bg-${color}-600`}> <div className="absolute inset-0 flex items-center justify-center"> {icon} </div> <div className={`absolute bottom-0 left-0 right-0 bg-gradient-to-t from-${color}-900 to-transparent h-1/2`}></div> <div className="absolute bottom-4 left-6"> <h3 className="text-2xl font-bold text-white">{title}</h3> </div> </div> <div className="p-6"> <p className="text-gray-700 mb-4">{description}</p> <ul className="space-y-2 mb-6"> {features.map((feature, index) => ( <li key={index} className="flex items-start"> <span className={`text-${color}-500 mr-2`}>•</span> <span>{feature}</span> </li> ))} </ul> <Link href={linkHref}> <Button className={`w-full bg-${color}-600 hover:bg-${color}-700`}>{linkText}</Button> </Link> </div> </div> );Then use it like:
<TechnologyCard title="Forecasting AI" description="Our forecasting AI predicts air quality conditions up to 7 days in advance with high accuracy. Using recurrent neural networks and ensemble methods, we analyze historical air quality data, weather patterns, and human activity to generate reliable forecasts." features={[ "Time-series prediction models", "Weather data integration", "Seasonal pattern recognition" ]} icon={<LineChart className="h-20 w-20 text-white opacity-30" />} color="blue" linkHref="/reports" linkText="Explore Forecasting" />Also applies to: 76-110, 113-147
267-267: Use typographically correct apostropheThe escaped apostrophe could be replaced with a straight apostrophe for better readability in the source code.
- We're continuously advancing our AI capabilities to address emerging challenges in air quality management: + We're continuously advancing our AI capabilities to address emerging challenges in air quality management:Since this is a Next.js application, it should handle the conversion automatically as long as you're using the latest JSX transform.
292-306: Enhance button accessibility and consistencyThe CTA section contains multiple buttons with inconsistent sizing and potentially unclear purposes for screen readers.
Consider standardizing the button styles and adding aria-labels:
<div className="flex flex-wrap justify-center gap-4"> <Link href="/map"> - <Button className="bg-white text-blue-700 hover:bg-blue-50 px-8 py-4 rounded-lg font-medium"> + <Button + className="bg-white text-blue-700 hover:bg-blue-50 px-8 py-4 rounded-lg font-medium" + aria-label="Explore the interactive air quality map" + > Explore the Map </Button> </Link> <Link href="/locate"> - <Button className="bg-transparent text-white hover:bg-white/10 border border-white px-8 py-4 rounded-lg font-medium"> + <Button + className="bg-transparent text-white hover:bg-white/10 border border-white px-8 py-4 rounded-lg font-medium" + aria-label="Try the air quality site locator tool" + > Try Site Locator </Button> </Link> <Link href="/categorize"> - <Button className="bg-transparent text-white hover:bg-white/10 border border-white px-8 py-4 rounded-lg font-medium"> + <Button + className="bg-transparent text-white hover:bg-white/10 border border-white px-8 py-4 rounded-lg font-medium" + aria-label="Use the air quality categorization tool" + > Use Categorization Tool </Button> </Link> </div>Also, consider extracting this into a reusable
CTAButtoncomponent to maintain consistency.
320-320: Remove unnecessary empty line at the end of fileThere's an empty line at the end of the file that isn't necessary.

21-21: Consider avoiding the delete operator for better performanceThe static analysis tool flags the use of the delete operator here as a potential performance issue. While this is a common pattern for Leaflet icon fixes, consider using an assignment instead.
- delete (L.Icon.Default.prototype as any)._getIconUrl + (L.Icon.Default.prototype as any)._getIconUrl = undefined🧰 Tools

[error] 20-21: Avoid the delete operator which can impact performance.
Unsafe fix: Use an undefined assignment instead.

110-119: Good cleanup implementation, but could be improvedAdding a cleanup function to remove the map reference from the global window object is a good practice. However, consider two improvements:
- Avoid using delete operator (flagged by static analysis)
- Consider using React context instead of modifying the global window object
- return () => { - // Clean up reference when component unmounts - if (window.map === map) { - delete window.map - } - } + return () => { + // Clean up reference when component unmounts + if (window.map === map) { + window.map = undefined + } + }For a more React-idiomatic approach, consider implementing a MapContext provider instead of using the global window object.

25-40: Consider centralizing URL resourcesThe marker and shadow URLs are hardcoded in multiple places. Consider extracting these to a central configuration object to improve maintainability.
// Example of a centralized config approach const mapResources = { markers: { blue: "https://raw.githubusercontent.com/pointhi/leaflet-color-markers/master/img/marker-icon-2x-blue.png", green: "https://raw.githubusercontent.com/pointhi/leaflet-color-markers/master/img/marker-icon-2x-green.png" }, shadow: "https://cdnjs.cloudflare.com/ajax/libs/leaflet/1.7.1/images/marker-shadow.png" } // Then use it like: // shadowUrl: mapResources.shadow

13-18: Global window.map declaration is a good improvementAdding proper TypeScript typing for the global window.map property enhances type safety throughout the application. The optional chaining operator (?) correctly indicates that this property might be undefined.
136-145: LGTM! Good implementation of location handlingThe implementation of the click handler in DrawControl correctly captures new locations and updates the polygon. The code properly manages the polygon state and references.
183-183: Clean and effective polygon renderingThe Polygon component implementation is clean and appropriately maps the location data to the format expected by react-leaflet.

Consider providing props to NavigationControls if needed
The NavigationControls component is rendered without any props. If this component requires context about the current map state, consider passing relevant information as props.
🏁 Script executed:
#!/bin/bash # Check if NavigationControls accepts/expects any props rg -A 3 -B 3 'function NavigationControls' frontend/src/componentsLength of output: 498
NavigationControls Component Props Verification
After verifying the component definition in
frontend/src/components/map/NavigationControls.tsx, it’s confirmed that theNavigationControlscomponent is implemented as a stateless function with no props. There’s no need to pass any props as the component does not expect any.
