Adding precision to millify ensures consistent number formatting with one decimal place.

Using the IconKeys type is more type-safe than the previous approach with keyof typeof Icons.

The hover effects align with PR objectives, but check GitHub metric icons.

The transition, scaling, and brand colors on hover match the PR requirements. However, previous review comments indicated these changes may have affected existing hover animations for GitHub metrics icons (stars, forks, etc.).

Action Required: Verify GitHub Metric Icons Hover Behavior

The updated hover classes in frontend/src/components/DisplayIcon.tsx (lines 22–24) meet the PR objectives. However, our CSS search shows that the only file referencing potential GitHub metric icon styles (e.g., for rotation/flip effects) is frontend/src/index.css. Please double-check that the new hover effects do not inadvertently override or conflict with the hover animations for GitHub metric icons (such as stars and forks):

• Ensure that any rules in frontend/src/index.css (or elsewhere) targeting classes like icon-rotate, icon-flip, or similar remain intact.
• Confirm via manual QA that GitHub metric icons retain their intended animations without interference from the transition-transform, hover:scale-110, or brand color classes applied to non-metric icons.

Update tooltip props to match new package API.

The tooltip props have been adjusted to work with the @heroui/tooltip package, but previous review comments indicate tooltips aren't appearing. Ensure that the new props (delay instead of openDelay, placement instead of positioning) are correct for the new package.

Action Required: Confirm Tooltip API Prop Changes

The tooltip component in frontend/src/components/DisplayIcon.tsx (lines 39 and 42) now uses the new props (delay instead of openDelay, and placement instead of positioning). However, our automated search couldn’t locate the @heroui/tooltip package or usage examples in the codebase to verify these changes. Please manually verify that these updated prop names align with the package’s current API.

• File: frontend/src/components/DisplayIcon.tsx

Brand color hover effects meet requirements but check applicability.

The implementation of brand colors on hover aligns with the PR objectives. However, ensure this is only applied to social media icons and not to GitHub metrics icons per previous review comments.

Also verify there's a consistent approach to color handling by examining:

---

🏁 Script executed:

#!/bin/bash
# Check where this component is used and with what item values

echo "Looking for DisplayIcon usage with social media items:"
grep -r "<DisplayIcon" --include="*.tsx" frontend/src/ | grep -E "item=['\"]discord|instagram|linkedin|youtube"

What are best practices for handling hover effects and brand colors for social media icons in React applications?

💡 Result:

To handle hover effects and brand colors for social media icons in React effectively, follow these best practices:

1. Use Dedicated Icon Libraries

• Leverage React-specific libraries like react-icons or react-social-icons to simplify implementation and ensure performance. These libraries provide optimized SVG icons and eliminate the need to load entire icon sets[5][6][10].

  // Example using react-social-icons[5]
  import { SocialIcon } from 'react-social-icons';
  
  <SocialIcon url="https://twitter.com" bgColor="#1DA1F2" /> 

• Import icons selectively to reduce bundle size:

  // Instead of importing all icons[6][10]
  import { FaTwitter } from 'react-icons/fa';

2. Brand Color Implementation

• Apply platform-specific brand colors using official HEX values:

  /* CSS class approach[1][8] */
  .twitter { color: #1DA1F2; }
  .youtube { color: #FF0000; }

  // Inline style method[2][5]
  <MDBBtn style={{ backgroundColor: '#1DA1F2' }}>

• Use dynamic props for color theming:

  <FontAwesomeIcon icon={faTwitter} color={isDarkMode ? '#fff' : '#1DA1F2'} />[1][4]

3. Hover Effects

• CSS transitions for smooth animations[1][3][8]:

  .social-icon {
    transition: transform 0.3s ease;
  }
  .social-icon:hover {
    transform: translateY(-3px);
    opacity: 0.8;
  }

• State-driven hover effects for complex interactions[3][9]:

  const [hovered, setHovered] = useState(false);
  
  <FaTwitter 
    color={hovered ? '#0D8ECF' : '#1DA1F2'}
    onMouseEnter={() => setHovered(true)}
    onMouseLeave={() => setHovered(false)}
  />

4. Accessibility & Semantics

• Add ARIA labels for screen readers[5][10]:

  <SocialIcon 
    aria-label="Follow us on Twitter"
    url="https://twitter.com"
  />

• Use semantic HTML:

  <a href="https://twitter.com" role="button">
    <FaTwitter />
  </a>

5. Performance Optimization

• Global icon configuration with IconContext.Provider[6][10]:

  <IconContext.Provider value={{ size: '2em', className: 'global-icons' }}>
    <FaTwitter />
    <FaFacebook />
  </IconContext.Provider>

• Lazy load non-critical icons using dynamic imports:

  const TwitterIcon = React.lazy(() => import('react-icons/fa').then(module => ({ default: module.FaTwitter })));

6. Responsive Design

• Use relative units for sizing[7][8]:

  <FaTwitter size="clamp(1.5rem, 3vw, 2rem)" />

• Media queries for hover behavior[3]:

  @media (hover: hover) {
    .social-icon:hover { /* styles */ }
  }

Recommended Implementation

import { SocialIcon } from 'react-social-icons';

const SocialIcons = () => (
  <div className="social-container">
    <SocialIcon 
      url="https://twitter.com" 
      bgColor="transparent"
      fgColor="#1DA1F2"
      className="social-icon"
      aria-label="Twitter"
    />
    <SocialIcon
      url="https://facebook.com"
      bgColor="transparent" 
      fgColor="#1877F2"
      className="social-icon"
      aria-label="Facebook"
    />
  </div>
);

.social-icon {
  transition: transform 0.3s ease, opacity 0.3s ease;
  margin: 0 12px;
}

.social-icon:hover {
  transform: translateY(-3px);
  opacity: 0.8;
}

@media (prefers-reduced-motion) {
  .social-icon {
    transition: none;
  }
}

This approach combines brand authenticity (using official colors[1][5]), accessibility[3][10], and performance[6][7] while maintaining visual polish through CSS transitions[1][8]. For complex use cases, consider combining with state management for dynamic interactions[3][9].

Action Required: Verify That Hover Effects Are Limited to Social Media Icons
The implementation of hover effects via getBrandColorClass conforms to the PR objectives and best practices for social media icon branding. However, please confirm that these brand-specific hover styles are only applied when the icon represents a social media channel (e.g. Discord, Instagram, LinkedIn, YouTube) and are not inadvertently used for GitHub metrics icons. In particular, note that our search located a usage in frontend/src/components/Card.tsx without clear evidence that it’s a social media icon. Verify that any such usage is appropriate or adjust the logic accordingly.

Test tooltip functionality for all icon types

Previous review comments repeatedly mentioned tooltips weren't appearing for social links.

Please verify tooltip functionality for all icon types, particularly social media icons. Run this script to check for potential issues:

---

🏁 Script executed:

#!/bin/bash
# Check if @heroui/tooltip package is installed
echo "Checking if @heroui/tooltip is installed:"
if [ -d "node_modules/@heroui/tooltip" ]; then
  echo "Package found in node_modules."
else
  echo "Package NOT found in node_modules. This could explain tooltip issues."
fi

# Check package.json for dependency
echo -e "\nChecking package.json dependencies:"
grep -E "@heroui/tooltip" package.json || echo "Not found in package.json"

# Check for other tooltip implementations
echo -e "\nChecking for tooltip component implementations:"
find frontend/src/components -type f -name "*.tsx" | xargs grep -l "Tooltip" | sort

Length of output: 984

Action Required: Verify Custom Tooltip Functionality for All Icon Types

The code in frontend/src/components/DisplayIcon.tsx now relies on our local Tooltip component (see frontend/src/components/ui/tooltip.tsx) rather than the external @heroui/tooltip package—which is neither installed in node_modules nor listed in the dependency file. Please manually test the tooltip behavior for all icon types, with particular focus on social media icons. Ensure that on hover the tooltip appears as expected with the correct delay and content. If any issues persist (especially with social links), further investigation into the custom Tooltip implementation may be required.
