🧹 Nitpick comments (8)
frontend/src/app/page.tsx (1)
15-17: Consider more concise comments.The comment "Add Navigation Component" is redundant since the code is self-documenting. Consider removing it or adding more meaningful context if needed.
frontend/src/components/feature-card.tsx (1)
11-17: Consider extracting Tailwind classes for reusability.The card styling classes could be moved to a constant or utility function using the
cnutility we have. This would make the styles more maintainable and reusable across similar components.+const cardStyles = cn( + "rounded-lg border bg-card p-6 transition-all hover:shadow-lg" +); + +const iconStyles = cn( + "h-12 w-12 text-blue-500" +); + export function FeatureCard({ title, description, Icon }: FeatureCardProps) { return ( - <div className="rounded-lg border bg-card p-6 transition-all hover:shadow-lg"> + <div className={cardStyles}> <div className="mb-4"> - <Icon className="h-12 w-12 text-blue-500" /> + <Icon className={iconStyles} />frontend/src/app/not-found.tsx (1)
10-12: Consider structured error logging.Instead of using
console.errordirectly, consider creating a dedicated logging utility that could handle different environments and logging levels.// utils/logger.ts export const logger = { error: (message: string, ...args: any[]) => { if (process.env.NODE_ENV !== 'production') { console.error(message, ...args); } // Add error tracking service integration here } };frontend/src/components/navigation/navigation.tsx (1)
8-14: Consider making navigation items configurable.The hardcoded navigation items could be moved to a configuration file for better maintainability.
Consider creating a
config/navigation.tsfile:export const navItems = [ { name: "Home", href: "/" }, { name: "About", href: "/about" }, { name: "Locate", href: "/locate" }, { name: "Categorize", href: "/categorize" }, { name: "Reports", href: "/reports" }, ] as const;frontend/src/ui/button.tsx (1)
7-34: Consider adding a loading state variant.The button variants are well-defined, but a loading state could be useful for async operations.
Add a loading variant:
variants: { variant: { default: "bg-primary text-primary-foreground hover:bg-primary/90", destructive: "bg-destructive text-destructive-foreground hover:bg-destructive/90", outline: "border border-input bg-background hover:bg-accent hover:text-accent-foreground", secondary: "bg-secondary text-secondary-foreground hover:bg-secondary/80", ghost: "hover:bg-accent hover:text-accent-foreground", link: "text-primary underline-offset-4 hover:underline", + loading: "bg-primary/50 text-primary-foreground cursor-not-allowed", },frontend/src/app/about/page.tsx (1)
26-43: Consider adding ARIA labels for better accessibility.The core values section could benefit from improved accessibility.
Add ARIA labels to the grid:
-<div className="grid grid-cols-1 md:grid-cols-3 gap-8 mb-12"> +<div + className="grid grid-cols-1 md:grid-cols-3 gap-8 mb-12" + role="region" + aria-label="Core Values" +>frontend/README.md (2)

Verify Navigation component path.
The import path uses the
@alias. Let's ensure this alias is properly configured in the TypeScript config.
🏁 Script executed:
#!/bin/bash # Check tsconfig.json for path alias configuration fd -t f tsconfig.json -x cat {} | jq '.compilerOptions.paths'Length of output: 286
Review: Confirm Correct TypeScript Alias for Navigation Component
It appears that the import
import Navigation from "@/components/navigation/navigation";uses the
@alias, whereas thetsconfig.jsonshows a mapping for"@components/*": ["./*"]. This mismatch may lead to unresolved module issues. Additionally, the shell script output contained JSON parse errors and repeated alias mappings, so the alias configuration might be coming from multiple sources or be misformatted.Please manually verify that the intended alias configuration is correct. Either update the import to use the alias defined in
tsconfig.json(e.g. change it to@components/navigation/navigation) or adjust thetsconfig.jsonpaths to include an alias for"@/*"if that is desired.frontend/src/app/not-found.tsx (1)

Review animation performance impact.
The component uses both transform and animation classes. While visually appealing, consider:
- The
animate-bounceon a large text element might affect performance- The
hover:scale-105transform might cause layout shiftsConsider using
will-changeor reducing animation complexity for better performance.

What are the performance implications of CSS animations in React?💡 Result:
CSS animations in React applications can offer excellent performance when implemented correctly, but they require careful consideration of browser rendering processes and React's component lifecycle. Here's a breakdown of key implications and optimization strategies:
Performance Characteristics
GPU Acceleration
CSS transforms/opacity enable off-main-thread animations through GPU compositing[1][5], while properties likewidth/heighttrigger costly layout recalculations[3][5]. Modern browsers optimizetransformandopacityanimations by handling them in separate compositor threads[1].Frame Rate Considerations
Target 60 FPS (16.7ms/frame) for smooth animations[3][5]. CSS animations typically maintain better frame consistency than JavaScript equivalents due to browser-level optimizations[1][3].React-Specific Overheads
Frequent component re-renders during animations can cause:
- Unnecessary reconciliation/diffing cycles
- Layout thrashing from style recalculations
- Memory pressure from rapid state updates[7][9]
Optimization Strategies
Technique Benefit Implementation Hardware-Accelerated Properties Bypass main thread rendering Use transform/opacityinstead of layout properties[2][5]Layer Promotion Enable GPU compositing Apply will-change: transformortranslateZ(0)[5]Animation Libraries Optimized update cycles Use Framer Motion's motioncomponents[4] or React SpringRequestAnimationFrame Align with browser paint cycles Replace setIntervalwith RAF for JS animations[9][10]Key React-Specific Recommendations:
// Good: Hardware-accelerated with Framer Motion const Button = () => ( <motion.button whileHover={{ scale: 1.1 }} whileTap={{ scale: 0.9 }} /> ); // Bad: Animating layout properties in state const [width, setWidth] = useState(100); useEffect(() => { // Triggers re-render every frame requestAnimationFrame(() => setWidth(w => w + 1)); }, []);Performance Pitfalls
- Layout Thrashing
Animating margin/padding forces synchronous layout calculations[5][7]- Memory Leaks
Uncleaned animation intervals/RAF callbacks[9]- Composite Layer Explosion
Excessivewill-changedeclarations consume GPU memory[5]Use Chrome DevTools' Performance tab to:
- Identify layout/paint storms
- Analyze composite layers
- Track frame drops[5][10]
For complex sequences, consider combining CSS
@keyframeswith React's lifecycle methods using the Web Animations API[10]. Always test animations on low-powered devices and use Intersection Observer to pause off-screen animations[10].Citations:

CSS Animation Performance Considerations
The current implementation leverages GPU-accelerated properties (i.e.,
transform) which modern browsers optimize. However, please review the following points to ensure robust performance, especially on low-powered devices:
- Animating Large Elements: The
animate-bounceclass on the oversized “404” text may introduce extra workload. Verify that the visual appeal justifies any potential performance trade-offs.- Hover Transformations: The
hover:scale-105effect could trigger layout shifts. Consider adding awill-change: transformproperty to the element to encourage layer promotion and smoother animations.- Performance Testing: Ensure that these animations maintain a consistent 60 FPS on target devices. Testing on lower-end hardware is recommended to identify any unexpected jank or layout recalculations.
Please adjust or optimize as necessary after verifying performance metrics in your application’s target environments.

12-25:✅ Verification successful
Verify compatibility with Next.js version.
Please ensure all new UI-related dependencies are compatible with Next.js 15.0.2.
🌐 Web query:
What are the minimum Next.js version requirements for @radix-ui/[email protected] and [email protected]?💡 Result:
The minimum Next.js version requirements for these packages can be determined through indirect evidence from development patterns and dependency relationships:
For @radix-ui/[email protected]:
- Works with Next.js ≥13 based on successful implementations in projects using:
- App Router architecture [1]
- Server Components [1]
next@13explicitly listed in package.json [1]For [email protected]:
- Requires Next.js ≥13 due to:
- Compatibility with React Server Components architecture [1][5]
- Integration patterns shown in projects using
next@13[1]- Peer dependency alignment with modern React features (concurrent rendering mode)
Key supporting evidence from search results:
- Both packages are used together in a production-grade app using
next@13[1]- Radix UI components require modern React features available since v18 [6][10]
- Lucide's tree-shaking works best with modern bundling approaches used in Next ≥13 [5][7]
While no explicit minimum versions are documented, these packages rely on architectural patterns introduced in Next.js v13 like App Router and Server Components[1]. Earlier versions (≤12) using Pages Router would likely encounter compatibility issues due to different bundling strategies and legacy React support[10].

frontend/src/components/map/NavigationControls.tsx (2)
1-9: Component structure looks good, but implementation is incomplete.The component is properly set up as a client-side component with correct positioning. However, it currently lacks any navigation controls that users would expect.
Could you clarify what navigation controls are planned for this component? Common map controls typically include:
- Zoom in/out buttons
- Reset view/center button
- Compass/rotation controls
- Full-screen toggle
I can help implement these controls once you confirm which ones are needed.
5-5: Consider accessibility improvements for the navigation controls container.While the positioning is correct, consider adding ARIA attributes and keyboard navigation support for the upcoming controls.

45-49: Consider moving map tile URLs to environment configuration.Hardcoding URLs in the component makes it less flexible for different environments or API changes.
+// Create a config file (e.g., config/maps.ts) +export const MAP_CONFIG = { + styles: { + streets: process.env.NEXT_PUBLIC_MAP_STREETS_URL || "https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", + satellite: process.env.NEXT_PUBLIC_MAP_SATELLITE_URL || "https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}", + } +};
136-155: Enhance cleanup in DrawControl useEffect.The cleanup function should also reset the locations reference to prevent stale state.
return () => { map.off("click", handleClick); drawingRef.current?.remove(); + locationsRef.current = []; };
170-174: Make map center and zoom configurable via props.Hardcoding the center coordinates and zoom level makes the component less reusable.
+interface MapComponentProps { + // ... existing props + initialCenter?: [number, number]; + initialZoom?: number; +} <MapContainer - center={[1.3733, 32.2903]} // Uganda center - zoom={7} + center={initialCenter ??
