What problem does it solve?

This Skill helps Next.js apps run GTM/GA analytics without blocking the initial render by replacing inline script patterns with a dynamic import approach via @next/third-parties. It reduces render-blocking JavaScript and improves Core Web Vitals while preserving analytics fidelity.

Core Features & Use Cases

  • Dynamic import pattern for GTM/GA using @next/third-parties to load analytics client-side after hydration.
  • Reduces render-blocking JavaScript and improves FCP, LCP, and TBT in production environments.
  • Use cases include migrating from inline <Script> tags to a reusable analytics wrapper in Next.js apps and applying the pattern to GA4 and GTM deployments.

Quick Start

  1. Install the required dependency: npm install @next/third-parties
  2. Create a small client wrapper component that dynamically loads GTM/GA after hydration
  3. Replace inline analytics Script usage in your root layout with the wrapper and set environment variables NEXT_PUBLIC_GTM_ID or NEXT_PUBLIC_GA_ID
