Vercel Speed Insights Installation Complete

Successfully installed and configured Vercel Speed Insights for the JavaScript30 project following the official Vercel documentation.

What was implemented:

  1. Fetched Latest Documentation

  2. Package Installation

    • The @vercel/speed-insights package (v2.0.0) was already present in package.json
    • Ran npm install to ensure dependencies are properly installed
    • Updated package-lock.json to reflect the correct dependency tree
  3. Speed Insights Integration

    • Added Speed Insights script to all 31 HTML files in the project:
      • Main index.html (already had it)
      • All 30 project pages (01-JavaScript-Drum-Kit through 30-Whack-A-Mole)
  4. Implementation Details

    • Following the vanilla HTML approach from the documentation, added the Speed Insights initialization script:
      <!-- Vercel Speed Insights -->
      <script>
          window.si = window.si || function () { (window.siq = window.siq || []).push(arguments); };
      </script>
      <script defer src="/_vercel/speed-insights/script.js"></script>
    • Placed the script in the <head> section, right after the existing Vercel Web Analytics script
    • This ensures consistency across all pages and proper loading order

Files Modified:

HTML Files (31 total):

  • All 30 project index.html files (01-JavaScript-Drum-Kit through 30-Whack-A-Mole)
  • Main index.html (already had Speed Insights)

Dependency Files:

  • package-lock.json (updated with proper dependency tree)

Implementation Notes:

  • Used the vanilla HTML/JavaScript approach as specified in the Vercel documentation for non-framework projects
  • The Speed Insights script uses the window.si global function pattern, similar to how Web Analytics uses window.va
  • The script loads asynchronously with defer to avoid blocking page rendering
  • The implementation follows the exact pattern from the official documentation
  • All pages now have both Web Analytics and Speed Insights configured consistently

Verification:

  • ✅ Dependencies installed successfully
  • ✅ All 31 HTML files now include Speed Insights
  • ✅ Tests pass (no tests defined in project)
  • ✅ No build errors or linting issues
  • ✅ Code structure preserved, only necessary changes added

Next Steps:

Once deployed to Vercel, Speed Insights will automatically start collecting Core Web Vitals data including:

  • Largest Contentful Paint (LCP)
  • First Input Delay (FID)
  • Cumulative Layout Shift (CLS)
  • First Contentful Paint (FCP)
  • Time to First Byte (TTFB)
  • Interaction to Next Paint (INP)

Data will be accessible via the Vercel dashboard under Speed Insights after the next deployment and user visits.

   - Retrieved the official Vercel Speed Insights quickstart guide from https://vercel.com/docs/speed-insights/quickstart
   - Identified that this is a vanilla HTML/JavaScript project, requiring the vanilla HTML implementation approach

2. **Package Installation**
   - The @vercel/speed-insights package (v2.0.0) was already present in package.json
   - Ran `npm install` to ensure dependencies are properly installed
   - Updated package-lock.json to reflect the correct dependency tree

3. **Speed Insights Integration**
   - Added Speed Insights script to all 31 HTML files in the project:
     - Main index.html (already had it)

     </script>
     <script defer src="/_vercel/speed-insights/script.js"></script>

### Implementation Notes:

- Used the vanilla HTML/JavaScript approach as specified in the Vercel documentation for non-framework projects
- The Speed Insights script uses the `window.si` global function pattern, similar to how Web Analytics uses `window.va`
- The script loads asynchronously with `defer` to avoid blocking page rendering
- The implementation follows the exact pattern from the official documentation
- All pages now have both Web Analytics and Speed Insights configured consistently
