Vercel Speed Insights Installation - Implementation Report

Summary

Successfully installed and configured Vercel Speed Insights for this Next.js 16.0.0 App Router project.

Changes Made

1. Package Installation

  • Installed @vercel/speed-insights version 1.2.0 using pnpm
  • Updated package.json to include the new dependency
  • Updated pnpm-lock.yaml with the new package and its dependencies

2. Component Integration

Modified: app/layout.tsx

  • Added import statement: import { SpeedInsights } from '@vercel/speed-insights/next'
  • Added <SpeedInsights /> component inside the <body> tag, placed after the <Analytics /> component
  • This follows Next.js 13.5+ App Router best practices for the root layout

Implementation Details

Why These Changes?

  • Next.js Version: The project uses Next.js 16.0.0 with App Router, so we used the @vercel/speed-insights/next import path
  • Placement: The component was added to the root layout (app/layout.tsx) to ensure Speed Insights is active across all pages
  • Position: Placed inside the <body> tag after <Analytics /> to maintain consistency with the existing analytics setup

Testing Performed

  1. ✅ Build verification: pnpm run build completed successfully
  2. ✅ Linting: pnpm run lint passed with no new errors introduced
  3. ✅ Type checking: TypeScript compilation successful during build

Files Modified

  • app/layout.tsx - Added SpeedInsights component import and usage
  • package.json - Added @vercel/speed-insights dependency
  • pnpm-lock.yaml - Updated with new package and dependencies

Notes

  • The implementation follows Vercel's official documentation for Next.js App Router
  • No breaking changes were introduced
  • The Speed Insights component will automatically track Web Vitals metrics when the application is deployed to Vercel
  • The component is lightweight and doesn't affect the application bundle size significantly
