# Vercel Speed Insights Implementation Report ## Summary Successfully implemented Vercel Speed Insights for the CAIRN ETP website following the latest official documentation. ## Changes Made ### 1. Package Installation - Installed `@vercel/speed-insights` v2.0.0 via npm - Updated `package.json` with the new dependency - Generated `package-lock.json` with locked dependency versions ### 2. Speed Insights Integration Added Vercel Speed Insights tracking scripts to both HTML pages: #### Modified Files: - **index.html** - Added Speed Insights initialization and script loader in the `<head>` section - **book.html** - Added Speed Insights initialization and script loader in the `<head>` section #### Implementation Details: Used the static site approach as recommended in the Vercel documentation: - Added initialization script that creates the `window.si` function and queue (`window.siq`) - Added deferred script tag to load `/_vercel/speed-insights/script.js` - Placed scripts at the end of the `<head>` section for optimal loading ### 3. Framework-Specific Approach This project is a static HTML/CSS/JS website served by FastAPI. Based on the Vercel documentation, I used the "without a package manager" approach which is ideal for static sites: - No build process changes required - No JavaScript module bundling needed - Clean inline script integration ## Verification Steps Completed ✅ Installed the @vercel/speed-insights package ✅ Added Speed Insights scripts to both HTML pages (index.html and book.html) ✅ Verified build completes successfully (`npm run build`) ✅ Validated HTML syntax for both files using Python HTML parser ✅ Confirmed Speed Insights script tags are present in both pages ✅ Updated package-lock.json with dependency resolution ## Next Steps for Deployment After deployment to Vercel: 1. Enable Speed Insights in the Vercel dashboard for this project 2. Deploy the updated code to Vercel 3. The `/_vercel/speed-insights/script.js` endpoint will be automatically available 4. Speed Insights will start collecting performance metrics automatically 5. View performance data in the Vercel Dashboard under Speed Insights ## Technical Notes - The implementation uses the recommended static site approach from the official Vercel documentation - Speed Insights will only track data in production mode (not in development) - The script loads with `defer` attribute to avoid blocking page rendering - Both main pages (homepage and book page) now include Speed Insights tracking - The FastAPI backend doesn't require any changes as it serves static HTML files ## Files Modified - `index.html` - Added Vercel Speed Insights scripts - `book.html` - Added Vercel Speed Insights scripts - `package.json` - Added @vercel/speed-insights dependency - `package-lock.json` - Generated with locked versions (new file) All changes preserve the existing code structure and only add the necessary Speed Insights functionality.
