# Vercel Web Analytics Installation

## Summary
Successfully installed and configured Vercel Web Analytics for the PetroBrain web application following the official Vercel documentation.

## Changes Made

### 1. Package Installation
- Installed `@vercel/analytics@^2.0.1` package using pnpm
- Added dependency to `frontend/apps/web/package.json`

### 2. Analytics Integration
- Modified `frontend/apps/web/app/layout.tsx`:
  - Added import: `import { Analytics } from '@vercel/analytics/next';`
  - Added `<Analytics />` component before the closing `</body>` tag

### 3. Framework Configuration
- Followed Next.js App Router instructions from the official Vercel Analytics quickstart guide
- The Analytics component is properly placed in the root layout to track all pages

## Files Modified
- `frontend/apps/web/app/layout.tsx` - Added Analytics component import and JSX element
- `frontend/apps/web/package.json` - Added @vercel/analytics dependency
- `frontend/pnpm-lock.yaml` - Updated with new package dependencies

## Implementation Details
- Used Next.js App Router approach as the project uses the `app/` directory structure
- Analytics component is placed at the end of the body tag to avoid blocking page rendering
- The implementation follows Vercel's official documentation exactly as retrieved from https://vercel.com/docs/analytics/quickstart

## Testing
- ESLint passes successfully (only pre-existing warnings about image optimization)
- The Analytics component will automatically start tracking page views once deployed to Vercel
- To verify proper setup after deployment, check the browser's Network tab for requests to `/<unique-path>/view`

## Next Steps
To complete the setup:
1. Deploy the application to Vercel
2. Enable Web Analytics in the Vercel dashboard (Analytics tab → Enable button)
3. Visit the deployed site to generate analytics data
4. View analytics in the Vercel dashboard

## Notes
- The build has pre-existing TypeScript errors in other parts of the codebase (unrelated to this change)
- The Analytics integration itself is correctly implemented and follows Vercel's best practices
- No breaking changes were introduced to existing functionality
