Set up Vercel Speed Insights tracking

Vercel Speed Insights Integration

Summary

Successfully integrated Vercel Speed Insights into the AI Glasses Platform project to enable performance monitoring and metrics collection.

Changes Made

Created:

• src/components/common/SpeedInsights.tsx - New React component that handles Speed Insights integration
  • Uses dynamic import to load the @vercel/speed-insights package
  • Calls injectSpeedInsights() on component mount
  • Returns null as it's a non-visual tracking component
  • Follows React best practices with useEffect hook

Modified:

• src/App.tsx - Integrated SpeedInsights component

  • Added import for the new SpeedInsights component
  • Placed SpeedInsights component at the top of the Router
  • Ensures tracking works across all pages and routes

• package.json - Added dependency

  • Added @vercel/speed-insights version ^1.3.1 to dependencies

• package-lock.json - Updated lockfile

  • Contains entries for the newly installed package and its dependencies

Implementation Details

Approach

The implementation uses a React component-based approach that's idiomatic for this Vite + React Router project:

1. Dedicated Component: Created a separate SpeedInsights component to keep concerns separated and make it easy to manage
2. Dynamic Import: Uses dynamic import to ensure the tracking script is only loaded on the client side
3. Optimal Placement: Component is placed early in the component tree (within Router but at the top of AuthProvider) to ensure tracking is initialized quickly
4. Non-intrusive: Returns null as it doesn't render any UI

Why This Approach?

• Client-side Only: The useEffect hook ensures the package is only loaded on the browser, not during server-side operations
• Lazy Loading: Dynamic import prevents the tracking library from blocking the initial bundle
• Framework Agnostic: While using React patterns, it aligns with the Vercel Speed Insights documentation for other frameworks
• Maintainable: Easy to disable or modify in future if needed

Next Steps for Users

Once this code is deployed to Vercel:

1. Enable Speed Insights in the Vercel dashboard for the project
2. Once enabled, Speed Insights will automatically track performance metrics
3. Navigate through the application to generate data
4. After a few days of user visits, metrics will be visible in the Vercel dashboard

Verification

• ✅ Package installed successfully (npm install @vercel/speed-insights)
• ✅ Build completes without errors (npm run build)
• ✅ Linter checks pass (no TypeScript or Biome errors)
• ✅ Component properly typed with TypeScript
• ✅ All imports and exports are correct
• ✅ Lock file updated to reflect new dependencies

Testing Notes

The implementation has been validated to:

• Build successfully with Vite
• Pass TypeScript type checking
• Pass linting checks
• Maintain backward compatibility with existing code
• Not break any existing routes or functionality
