Tech Tip Tuesday: 5 Ways to Speed Up Your Next.js App

Next.js is awesome, but your app can feel sluggish if you don’t optimize it. Here are 5 quick tips to make it run faster:

1️⃣ Use Dynamic Imports & Lazy Loading

  • Reduce initial load time by dynamically importing components:
import dynamic from "next/dynamic";
const HeavyComponent = dynamic(() => import("../components/HeavyComponent"), { ssr: false });
Enter fullscreen mode Exit fullscreen mode

2️⃣ Optimize Images with Next.js Image Component

  • Instead of using <img>, leverage Next.js's built-in <Image> component for better compression & lazy loading:
import Image from "next/image";  
<Image src="/hero.jpg" width={500} height={300} alt="Hero image" />
Enter fullscreen mode Exit fullscreen mode

3️⃣ Enable Automatic Static Optimization

  • Use getStaticProps() or getStaticPaths() to pre-render pages at build time for better performance.

4️⃣ Reduce Bundle Size with Code Splitting

  • Analyze your bundle size with next build + next analyze to remove unused dependencies.

5️⃣ Leverage Edge Functions & Middleware

  • Move logic closer to users with Edge Functions to improve speed and scalability.
