From da03f87b9935ada9a96c52f68ebe679009f5df7f Mon Sep 17 00:00:00 2001 From: Vercel Date: Sat, 17 Jan 2026 15:16:49 +0000 Subject: [PATCH] Add Vercel Speed Insights to Next.js MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented Vercel Speed Insights for Next.js ## What was implemented: Successfully installed and configured Vercel Speed Insights for the Next.js 15.1.0 project using the App Router. ## Changes made: ### 1. Package Installation - Installed `@vercel/speed-insights` (v1.3.1) using npm - Updated package.json and package-lock.json with the new dependency ### 2. Code Changes **Modified: `app/layout.tsx`** - Added import: `import { SpeedInsights } from '@vercel/speed-insights/next'` - Added `` component inside the `` tag, after the `` component - Placement follows best practices for Next.js 13.5+ with App Router ## Why these implementation choices: 1. **App Router Detection**: The project uses Next.js 15.1.0 (newer than 13.5) with the App Router (confirmed by presence of `app/layout.tsx` and absence of `pages/_app.tsx`), so the `@vercel/speed-insights/next` import was the correct choice. 2. **Placement Strategy**: The SpeedInsights component is placed in the root layout's body tag, after the Analytics component, which ensures it's loaded on every page without requiring duplicate imports across multiple layouts. 3. **Zero Disruption**: The implementation preserves all existing code structure and only adds the minimal necessary changes. The existing Vercel Analytics component is left untouched. 4. **Package Manager**: Used npm (detected by package-lock.json) to maintain consistency with the project's dependency management. ## Testing & Verification: - ✅ Build completed successfully (npm run build) - ✅ No build errors or warnings introduced - ✅ Project compiles with the SpeedInsights component integrated - ✅ All 14 static pages generated successfully during build ## Files Modified: - `app/layout.tsx` - Added SpeedInsights import and component - `package.json` - Added @vercel/speed-insights dependency - `package-lock.json` - Updated with new dependency details The implementation is minimal, focused, and follows Next.js best practices for performance monitoring integration.
