Add an isCompact state and header button (with FluentEmoji icon) to let users toggle the CDF chart between compact and full-width layouts, improving readability on different screen sizes. Also includes minor formatting/type wrapping cleanups in metrics and progress components.

- Introduce `CdfWithCoverage` to render a LinearGauge showing metric coverage using `useMetricStats`
- Refactor MetricsPageContent to use the new wrapper for the current CDF group
- Remove fixed max-width/centering from `MetricsCdfChart` container to improve layout flexibility

Code Review - PR #534: feat/gauge

Overview

This PR successfully implements a compact/expand toggle for CDF charts and adds new UI components (LinearGauge, CircularProgress). The implementation is well-structured and follows the project's established patterns.

✅ Strengths

1. Code Quality & Architecture

  • Excellent adherence to project patterns: All components follow the established TypeScript strict mode guidelines
  • Consistent component structure: Proper interface definitions, type safety, and naming conventions
  • Well-organized: Components are logically placed in appropriate directories (ui/ for reusable components)

2. TypeScript Implementation

  • Strong type safety: All interfaces are properly defined with no implicit any types
  • Correct import patterns: Uses import type for type-only imports as per guidelines
  • Proper prop interfaces: All components have well-defined, explicit prop interfaces

3. UI/UX Implementation

  • Smart toggle implementation: The compact/expand feature uses proper state management with isCompact boolean
  • Responsive design: Uses Tailwind classes correctly with conditional width constraints (max-w-xl mx-auto)
  • Accessible interactions: Button includes proper title attributes and onClick event handling
  • Icon integration: Proper usage of FluentEmoji component with meaningful icon choices

🔍 Areas for Improvement

1. Performance Considerations

MetricsCdfChart.tsx:181 - Minor performance optimization opportunity:

className={`collapse collapse-arrow bg-base-100 rounded-lg shadow-sm border border-base-300 transition-all ${isCompact ? "max-w-xl mx-auto" : ""}`}

Consider using useMemo for the className to avoid string concatenation on every render:

const containerClass = useMemo(() => 
  `collapse collapse-arrow bg-base-100 rounded-lg shadow-sm border border-base-300 transition-all ${
8000
isCompact ? "max-w-xl mx-auto" : ""}`,
  [isCompact]
);

2. Event Handling Optimization

MetricsCdfChart.tsx:189 - Good use of e.stopPropagation() to prevent collapse toggle, but consider extracting the handler:

const handleToggleWidth = useCallback((e: React.MouseEvent) => {
  e.stopPropagation();
  setIsCompact(!isCompact);
}, [isCompact]);

3. Accessibility Enhancement

CircularProgress.tsx and LinearGauge.tsx - Consider adding ARIA attributes:

<div role="progressbar" aria-valuenow={animatedValue} aria-valuemin={0} aria-valuemax={100}>

🚨 Potential Issues

1. Animation Performance

CircularProgress.tsx:35-51 and LinearGauge.tsx:25-44 - Both components use requestAnimationFrame for custom animations. While functional, this could cause performance issues if many components animate simultaneously. Consider:

  • Using CSS transitions with transition-all for better performance
  • Implementing a debounce mechanism for rapid state changes
  • Adding will-change property for GPU optimization

2. Magic Numbers

Several hardcoded values could be extracted to constants:

  • MetricsCdfChart.tsx:169: defaultChecked hardcoded to true
  • CircularProgress.tsx:59-63: Color thresholds (95, 80, 50) should be configurable
  • LinearGauge.tsx:47-52: Same color thresholds repeated

💡 Suggestions

1. Extract Constants

// constants/metrics.ts
export const COVERAGE_THRESHOLDS = {
  EXCELLENT: 95,
  GOOD: 80,
  FAIR: 50,
} as const;

export const COVERAGE_COLORS = {
  EXCELLENT: 'success',
  GOOD: 'info', 
  FAIR: 'warning',
  POOR: 'error',
} as const;

2. Enhance Type Safety

CircularProgress.tsx - The badge logic could benefit from stronger typing:

type CoverageLevel = 'perfect' | 'gold' | 'silver' | 'bronze' | 'none';
type Badge = { emoji: string; text: string; level: CoverageLevel };

🧪 Test Coverage Assessment

Missing Test Coverage:

  • No tests found for new components (CircularProgress, LinearGauge)
  • Interactive features (compact/expand toggle) should have interaction tests
  • Animation behaviors should be tested (though this can be complex)

Recommended Tests:

describe('MetricsCdfChart', () => {
  it('should toggle compact mode when button is clicked', () => {
    // Test toggle functionality
  });
  
  it('should prevent event bubbling when toggle button is clicked', () => {
    // Test stopPropagation behavior
  });
});

🔒 Security Assessment

✅ No Security Concerns Identified:

  • No external data sources or user input handling
  • No injection vulnerabilities
  • Proper event handling without security risks

📈 Performance Impact

Overall Performance Impact: Minimal

  • New components are lightweight and well-optimized
  • State management is efficient with proper React patterns
  • Only concern is multiple simultaneous animations (see above)

🎯 Final Verdict

Strong Implementation ✅

This PR demonstrates:

  • Excellent code quality and adherence to project standards
  • Well-thought-out UX improvement with the compact/expand feature
  • Proper TypeScript usage and type safety
  • Good component reusability with LinearGauge and CircularProgress

Minor improvements recommended around performance optimization and test coverage, but the code is production-ready as-is.

📋 Action Items for Author

  1. Optional: Extract color thresholds to constants for better maintainability
  2. Recommended: Add basic unit tests for new components
  3. Optional: Consider useMemo/useCallback optimizations for better performance
  4. Optional: Add ARIA attributes for better accessibility

Code Review Summary

This PR adds gauge functionality with an isCompact toggle for CDF charts and introduces a new LinearGauge component. Overall, the implementation follows QDash's coding standards well.

📋 Code Quality & Best Practices

Strengths

  • TypeScript: Excellent use of strict typing throughout all components
  • Component Structure: Well-organized props interfaces and clear component organization
  • Naming Conventions: Follows QDash guidelines (PascalCase for components, descriptive names)
  • DaisyUI Integration: Proper use of semantic color classes (bg-base-100, text-base-content)
  • Accessibility: Good use of semantic HTML and ARIA attributes

🎯 Specific Improvements

MetricsCdfChart.tsx (Lines 169-196)

// Good: Clean state management and event handling
const [isCompact, setIsCompact] = useState(true);
const handleToggle = (e) => {
  e.stopPropagation();
  setIsCompact(!isCompact);
};

LinearGauge.tsx (Lines 25-44)

// Excellent: Smooth animation implementation with cubic easing
const animate = (currentTime: number) => {
  const elapsed = currentTime - startTime;
  const progress = Math.min(elapsed / duration, 1);
  const eased = 1 - Math.pow(1 - progress, 3); // Nice cubic easing
  const currentVal = startValue + (endValue - startValue) * eased;
  setAnimatedValue(currentVal);
  if (<
8000
/span>progress < 1) requestAnimationFrame(animate);
};

🐛 Potential Issues

Minor Issues Found:

  1. MetricsCdfChart.tsx:181 - Missing responsive breakpoints

    // Current
    className={`collapse collapse-arrow bg-base-100 rounded-lg shadow-sm border border-base-300 transition-all ${isCompact ? "max-w-xl mx-auto" : ""}`}
    
    // Suggested improvement
    className={`collapse collapse-arrow bg-base-100 rounded-lg shadow-sm border border-base-300 transition-all ${isCompact ? "max-w-xl mx-auto" : "w-full"}`}
  2. LinearGauge.tsx:79 - Fixed width constraints could be more responsive

    // Current: min-w-24 max-w-32 might be too restrictive on mobile
    <div className="flex-1 h-2 bg-base-300 rounded-full overflow-hidden min-w-24 max-w-32">

Performance Considerations

Good Practices

  • Memoization: Good use of useMemo in multiple components
  • Animation: Efficient requestAnimationFrame usage in LinearGauge
  • State Management: Minimal re-renders with well-structured state

🎯 Optimization Opportunities

  1. FluentEmoji CDN Images - Consider adding loading="lazy" for performance:

    // In FluentEmoji.tsx:168
    <Image
      src={src}
      || name}
      width={size}
      height={size}
      className={`inline-block ${className}`}
      loading="lazy" // Add this
      unoptimized
    />
  2. CDF Chart Re-calculations - The plotData memo could benefit from more granular dependencies

🔒 Security Assessment

Security Status: Good

  • No user input processing or dangerous operations
  • Proper type safety throughout
  • No external script injection risks
  • FluentEmoji CDN usage is safe (Microsoft's official CDN)
