Vercel Speed Insights Installation Report

Summary

Successfully installed and configured Vercel Speed Insights for the rto.GiO project following the latest official documentation from Vercel.

Project Analysis

  • Framework: Vanilla HTML/JavaScript static site
  • Package Manager: npm (confirmed by package-lock.json)
  • Deployment Platform: Vercel (serverless functions in /api)
  • Architecture: Multi-page HTML application with client-side JavaScript

Implementation Details

1. Package Installation

  • Installed @vercel/speed-insights version 2.0.0 using npm
  • Package added to dependencies in package.json
  • package-lock.json updated with new dependency tree (95 packages added)

2. Speed Insights Integration

Since this is a vanilla HTML/JavaScript project (not a framework like Next.js, React, or Vue), I followed the HTML-specific integration approach from the official Vercel documentation:

Files Modified:

  • index.html - Main store page
  • admin.html - Admin dashboard page

Implementation:
Added the Speed Insights script to the <head> section of both HTML files:

<script>
  window.si = window.si || function () { (window.siq = window.siq || []).push(arguments); };
</script>
<script defer src="/_vercel/speed-insights/script.js"></script>

This approach:

  • Initializes the Speed Insights queue (window.si and window.siq)
  • Loads the Speed Insights script asynchronously using the defer attribute
  • Uses Vercel's built-in Speed Insights route (/_vercel/speed-insights/script.js)

3. Why This Approach?

According to the official Vercel Speed Insights quickstart documentation:

  • For vanilla HTML/JavaScript projects without a framework, the recommended approach is to add the script tag directly to the HTML
  • The defer attribute ensures the script loads without blocking page rendering
  • The queue initialization (window.si) allows for immediate tracking even before the script fully loads
  • Vercel automatically serves the Speed Insights script when deployed

4. Coverage

Speed Insights has been added to:

  • ✅ Main store page (index.html) - tracks customer browsing and ordering
  • ✅ Admin dashboard (admin.html) - tracks admin interface performance

Both pages will now send performance metrics to Vercel's Speed Insights dashboard.

Next Steps (To Be Done After Deployment)

  1. Deploy the project to Vercel (or push to connected Git repository)
  2. Enable Speed Insights in the Vercel dashboard (Project Settings → Speed Insights → Enable)
  3. After deployment and user visits, view performance metrics in the Vercel dashboard
  4. Monitor Core Web Vitals (LCP, FID, CLS) and other performance indicators

Files Changed

  • package.json - Added @vercel/speed-insights dependency
  • package-lock.json - Updated with new dependency tree
  • index.html - Added Speed Insights script tags
  • admin.html - Added Speed Insights script tags

Verification

  • ✅ Package successfully installed (95 packages added)
  • ✅ Scripts added to both HTML files in the correct location (head section)
  • ✅ HTML syntax validated (no errors)
  • ✅ Existing code structure preserved
  • ✅ No breaking changes introduced

Notes

  • This is a static site with no build process, so no build verification was necessary
  • No tests or linters are configured in the project
  • The Speed Insights script will only become active after deployment to Vercel
  • All changes follow Vercel's official documentation retrieved on March 19, 2026

# Vercel Speed Insights Installation Report

## Summary
Successfully installed and configured Vercel Speed Insights for the rto.GiO project following the latest official documentation from Vercel.

## Project Analysis
- **Framework**: Vanilla HTML/JavaScript static site
- **Package Manager**: npm (confirmed by package-lock.json)
- **Deployment Platform**: Vercel (serverless functions in /api)
- **Architecture**: Multi-page HTML application with client-side JavaScript

## Implementation Details

### 1. Package Installation
- Installed `@vercel/speed-insights` version 2.0.0 using npm
- Package added to dependencies in package.json
- package-lock.json updated with new dependency tree (95 packages added)

### 2. Speed Insights Integration
Since this is a vanilla HTML/JavaScript project (not a framework like Next.js, React, or Vue), I followed the HTML-specific integration approach from the official Vercel documentation:

**Files Modified:**
- `index.html` - Main store page
- `admin.html` - Admin dashboard page

**Implementation:**
Added the Speed Insights script to the `<head>` section of both HTML files:
```html
<script>
  window.si = window.si || function () { (window.siq = window.siq || []).push(arguments); };
</script>
<script defer src="/_vercel/speed-insights/script.js"></script>
```

This approach:
- Initializes the Speed Insights queue (`window.si` and `window.siq`)
- Loads the Speed Insights script asynchronously using the `defer` attribute
- Uses Vercel's built-in Speed Insights route (`/_vercel/speed-insights/script.js`)

### 3. Why This Approach?
According to the official Vercel Speed Insights quickstart documentation:
- For vanilla HTML/JavaScript projects without a framework, the recommended approach is to add the script tag directly to the HTML
