# Vercel Speed Insights Installation Report ## Summary Successfully installed and configured Vercel Speed Insights for Spectrix AI, a static HTML/JavaScript PWA project. ## Implementation Details ### Approach Since Spectrix AI is a pure static HTML/JavaScript project without a build process, I implemented Speed Insights using the CDN approach with ES module imports. This is the recommended method for static sites according to Vercel's documentation. ### Changes Made #### 1. Created package.json (new file) - Added `@vercel/speed-insights@^2.0.0` as a dependency - This provides package management and documents the dependency - The actual integration uses the CDN version for zero-build-step deployment #### 2. Modified index.html - Added Speed Insights integration script in the `<head>` section - Placed before the closing `</head>` tag, after Firebase scripts - Uses ES module import from jsDelivr CDN: `https://cdn.jsdelivr.net/npm/@vercel/speed-insights@2.0.0/+esm` - Calls `injectSpeedInsights()` which automatically: - Initializes the Speed Insights tracking - Loads the Vercel Speed Insights script from `/_vercel/speed-insights/script.js` (when deployed) - Sets up Web Vitals collection (LCP, FID, CLS, FCP, TTFB) #### 3. Line Ending Normalization - Converted index.html from Windows (CRLF) to Unix (LF) line endings for consistency #### 4. Generated package-lock.json - Locked the dependency version for consistency across environments ### How It Works The integration adds a small inline script that: 1. Imports the `injectSpeedInsights` function from the @vercel/speed-insights package via CDN 2. Calls the function to initialize Speed Insights tracking 3. The function automatically injects the Vercel tracking script into the page 4. Speed Insights will start collecting Web Vitals metrics in production ### Framework-Specific Notes This project is a vanilla JavaScript/HTML static site with: - No build process - No package bundler (webpack, vite, etc.) - PWA support with service worker - Firebase integration The CDN approach is perfect for this setup because: - Zero build step required - Works immediately on deployment to Vercel - No bundle size increase - Automatic updates via CDN versioning ### Testing - ✅ HTML structure validated (matching opening/closing tags) - ✅ Speed Insights script properly integrated in HTML - ✅ Import statement verified - ✅ No linting errors (project has no linter configured) - ✅ No tests to run (project has no test suite) ### Next Steps After deployment to Vercel: 1. Speed Insights will automatically start collecting data 2. View metrics in the Vercel dashboard under Speed Insights section 3. Data appears after real user visits (typically within hours to days) 4. Metrics include Core Web Vitals: LCP, FID, CLS, FCP, TTFB ### Files Modified - `index.html` - Added Speed Insights integration script - `package.json` (new) - Added dependency management - `package-lock.json` (new) - Locked dependency versions ### Documentation Reference Implementation follows the official Vercel Speed Insights quickstart guide: https://vercel.com/docs/speed-insights/quickstart The vanilla JavaScript approach uses the main export from @vercel/speed-insights package, which provides the `injectSpeedInsights()` function for non-framework projects.
