Next.js: Optimizing Dynamic Routes

Are you using static rendering (SSG) with Next.js to optimize performance? That’s a great start! But what about your dynamic routes? Are they optimized?

Many developers focus on SSG and overlook dynamic routes. Here are 5 strategies to boost their performance:

1️⃣ Client Cache (Router Cache)

• Use staleTime to cache pages on the client after the first load.
  👉 This makes subsequent loads nearly instant.

2️⃣ Request Memoization

• With React Cache, you can memoize API or database requests (e.g., Prisma calls).
  👉 Ensures that each request runs only once, even if called multiple times. Works with fetch too! (Note: limited to the lifecycle of the request)

3️⃣ Server Cache (Data Cache)

• Next.js extends the fetch API to enable server-side data caching.
  👉 Cached data is shared and persists for a defined duration, reducing response times.

4️⃣ unstable_cache or use Cache

• These APIs let you cache any kind of data with a key-value system.
  👉 Similar to TanStack Query, but integrated into Next.js backend for greater flexibility.

5️⃣ Choosing the right database region

• Hosting your database close to your users is critical.
  👉 For instance, if most users are in Europe, host your database in a European region to reduce latency.

Mastering these optimizations will set you apart from other developers!

All of this is covered in Next Mastery, where we dive deep into building FullStack apps with Next.js. Session 2 starts next week! 🚀
