Vercel Speed Insights Implementation Report

Summary

Successfully installed and configured Vercel Speed Insights for the Next.js 16.1.6 application using the App Router pattern.

Changes Made

1. Package Installation

  • Added dependency: @vercel/speed-insights@^1.3.1 to package.json
  • Updated lock file: package-lock.json with all required dependencies

2. Configuration in Root Layout

File: frontend/app/layout.tsx

Changes:

  • Import added: import { SpeedInsights } from "@vercel/speed-insights/next";
  • Component added: <SpeedInsights /> inside the <body> tag, after the {children} component

The implementation follows the recommended pattern for Next.js 13.5+ with App Router, where:

  • The SpeedInsights component is imported from @vercel/speed-insights/next
  • It's placed in the root layout file to track all pages
  • No additional configuration is needed as the component automatically detects routes in App Router

Implementation Details

Why This Approach?

The project uses:

  • Next.js version: 16.1.6 (>= 13.5)
  • Router type: App Router (confirmed by presence of app/layout.tsx)
  • Package manager: npm (confirmed by package-lock.json)

For Next.js 13.5+ with App Router, the recommended approach is to:

  1. Import from @vercel/speed-insights/next (not /react)
  2. Add the component directly without usePathname() or route props
  3. Place it in the root layout inside the <body> tag

Placement Decision

The <SpeedInsights /> component was placed after {children} within the <body> tag to ensure:

  • It loads after the main content
  • It doesn't block the initial render
  • It tracks all pages uniformly from the root layout

Verification

✅ Completed

  • Package successfully installed via npm install @vercel/speed-insights
  • Component properly imported and added to layout.tsx
  • Lock file automatically updated with dependency tree
  • Linter executed (no new errors introduced by our changes)
  • Code follows existing patterns and TypeScript conventions

⚠️ Note on Build

The build command encountered a pre-existing error related to missing Supabase environment variables. This is unrelated to the Speed Insights implementation. Our changes are syntactically correct and follow Next.js best practices.

No Tests Available

The project does not have a test suite configured (npm test is not available).

Files Modified

  1. frontend/app/layout.tsx - Added SpeedInsights import and component
  2. frontend/package.json - Added @vercel/speed-insights dependency
  3. frontend/package-lock.json - Updated with new dependency tree

Next Steps

When the application is deployed to Vercel:

  1. Speed Insights will automatically start collecting Core Web Vitals data
  2. Data can be viewed in the Vercel dashboard under the Speed Insights tab
  3. No additional configuration or environment variables are required

The implementation is production-ready and follows Vercel's official documentation.
