Implement performance optimizations

[amiable-dev]

Description

Several performance optimizations could be implemented to improve the site's loading speed and overall user experience.

Current Performance Gaps

1. FontAwesome icons are loaded as a full package
2. No explicit caching strategy defined
3. Image optimization could be improved

Proposed Solutions

1. Optimize FontAwesome Usage

Replace the current FontAwesome implementation with a more efficient approach:

// Instead of importing full packages:
import { library } from '@fortawesome/fontawesome-svg-core'
import { fab } from '@fortawesome/free-brands-svg-icons'

// Import only needed icons:
import { faGithub, faLinkedin, faTwitter } from '@fortawesome/free-brands-svg-icons'
library.add(faGithub, faLinkedin, faTwitter)

2. Implement Caching Strategy

Add caching configurations in docusaurus.config.js:

module.exports = {
  // ... other config
  staticDirectories: ['static'],
  customFields: {
    cacheControl: {
      '/assets/': 'public, max-age=31536000',
      '/static/': 'public, max-age=31536000',
      '/': 'public, max-age=0, must-revalidate'
    }
  }
}

3. Image Optimization

• Implement WebP format with fallbacks
• Add lazy loading for images below the fold
• Set explicit width/height attributes

Acceptance Criteria

• Bundle size reduced by optimizing FontAwesome imports
• Caching strategy implemented and verified
• Images optimized and properly configured
• Lighthouse performance score improved
• No regression in site functionality
• Documentation updated with performance optimization details

Performance Metrics to Monitor

• First Contentful Paint (FCP)
• Largest Contentful Paint (LCP)
• Total Blocking Time (TBT)
• Cumulative Layout Shift (CLS)
• Bundle size

Additional Notes

• Run performance audits before and after changes
• Consider implementing monitoring for ongoing performance tracking
