Vercel Web Analytics & Speed Insights Implementation Summary

Overview

This document summarizes the successful implementation of Vercel Web Analytics and Speed Insights for the Sharothee Wedding website.

Implementation Date

October 12, 2025

Changes Made

1. Package Installation

Web Analytics

  • Package: @vercel/analytics@1.5.0
  • Installation Command: npm install @vercel/analytics
  • Location: Added to client/package.json dependencies

Speed Insights

  • Package: @vercel/speed-insights@1.1.0
  • Installation Command: npm install @vercel/speed-insights
  • Location: Added to client/package.json dependencies

2. Code Integration

File Modified: client/src/app/layout.tsx

Imports Added (Lines 8-9):

import { Analytics } from "@vercel/analytics/react";
import { SpeedInsights } from "@vercel/speed-insights/next";

Components Added (Lines 69-70):

<Analytics />
<SpeedInsights />

Full Context: Both components are placed at the end of the <body> tag, just before the closing tag:

<body className="font-sans antialiased bg-cream-50 text-gray-800">
  <Providers>
    <ErrorBoundary>
      <Suspense fallback={null}>
        <RouteLoader />
      </Suspense>
      {children}
    </ErrorBoundary>
  </Providers>
  <Analytics />        {/* ← Web Analytics */}
  <SpeedInsights />    {/* ← Speed Insights */}
</body>

3. Testing

Test File Created: client/src/__tests__/Analytics.test.tsx

Test Coverage:

  • ✅ Verifies @vercel/analytics is in package.json dependencies
  • ✅ Verifies @vercel/speed-insights is in package.json dependencies
  • ✅ Confirms Analytics import in root layout file
  • ✅ Confirms SpeedInsights import in root layout file
  • ✅ Validates Analytics component placement in body tag
  • ✅ Validates SpeedInsights component placement in body tag

Test Results:

Test Suites: 10 passed, 10 total
Tests:       33 passed, 33 total
All tests pass ✓

4. Build Verification

Build Status:

✓ Compiled successfully in 13.1s
✓ Generating static pages (34/34)
✓ All routes compiled successfully

Validation Checks:

  • ✅ TypeScript type-check: Passed
  • ✅ ESLint: No errors or warnings
  • ✅ Production build: Successful (34 routes)
  • ✅ Development server: Starts correctly

How It Works

Development Environment

  • Both Analytics and SpeedInsights components are no-op in development
  • No data is collected locally
  • Zero performance impact during development

Production Environment (Vercel)

Web Analytics

When deployed to Vercel, the Analytics component automatically:

  1. Tracks Page Views: Uses Next.js App Router for automatic page tracking
  2. Collects Web Vitals: Measures CLS, FID, LCP, FCP, TTFB
  3. Monitors Performance: Real user monitoring (RUM)
  4. Analyzes Traffic: Geographic and device analytics

Speed Insights

When deployed to Vercel, the SpeedInsights component automatically:

  1. Real User Monitoring: Tracks actual user experiences
  2. Performance Scores: Measures page speed in production
  3. Web Vitals Tracking: LCP, FID, CLS, INP, TTFB
  4. Route-based Analytics: Per-page performance insights

Data Collection

  • Automatic: No additional configuration needed
  • Privacy-Focused: No cookies, GDPR compliant
  • Lightweight: Combined ~2KB gzipped bundle size
  • Fast: Non-blocking, async loading

Deployment Instructions

Step 1: Deploy to Vercel

# If using Vercel CLI
vercel --prod

# Or push to main branch if GitHub integration is enabled
git push origin main

Step 2: Enable Analytics & Speed Insights in Vercel Dashboard

  1. Go to Vercel Dashboard
  2. Select your project: "Sharothee-Wedding-arvinwedsincia"
  3. Navigate to Analytics tab
  4. Click Enable Analytics (if not already enabled)
  5. Navigate to Speed Insights tab
  6. Click Enable Speed Insights (if not already enabled)

Step 3: View Analytics & Speed Insights Data

  • Data appears within 24 hours of first deployment
  • Access via:
    • Vercel Dashboard → Your Project → Analytics
    • Vercel Dashboard → Your Project → Speed Insights

Troubleshooting

Analytics Not Showing Data

Possible Causes:

  1. Less than 24 hours since deployment
  2. Analytics not enabled in Vercel Dashboard
  3. Environment not detected as production

Solutions:

  1. Wait 24 hours for data to appear
  2. Enable Analytics in Vercel Dashboard
  3. Verify VERCEL environment variable is set

Build Failures

Possible Causes:

  1. Package not installed correctly
  2. Import path incorrect

Solutions:

  1. Run npm install in client directory
  2. Verify import: import { Analytics } from "@vercel/analytics/react"

Performance Issues

Possible Causes:

  1. Analytics loading synchronously

Solutions:

  1. Verify Analytics component is at end of <body> tag
  2. Check network tab for async loading
  3. Analytics should not block page rendering
