Caching Strategy in Next.js 2026 – What I Use Now

Hey everyone,

Caching is one of the things that tends to cause the most confusion in Next.js, especially since the App Router. After trying various combinations, here's the approach I use most often now.

1. Understand the Types of Cache First

I distinguish between 3 levels:

Request Memoization → React cache() (single request only)
Data Cache → fetch cache / unstable_cache
Full Route Cache → Static rendering

2. The Strategy I Follow

A. Data that rarely changes

import { unstable_cache } from "next/cache";

const getProducts = unstable_cache(
  async () => {
    return await db.product.findMany();
  },
  ["products"],
  { revalidate: 3600 }, // 1 hour
);

B. Data that changes fairly often I use revalidate: 60 or revalidateTag.

C. Data that must always be fresh

fetch(url, { cache: "no-store" });

3. The Revalidation Approach I Like

Time-based (revalidate: number) → simple and predictable
On-demand (revalidateTag / revalidatePath) → more powerful

I often combine the two.

4. Things I Avoid

Don't cache all data by default
Don't forget to invalidate the cache after a mutation
Don't over-cache data that's highly personal / user-specific

5. Practical Tips

Start with static first, then add dynamic only when needed
Use loading.tsx so users still get feedback
Monitor the cache hit rate in production
Document the tags you use so they're easy to revalidate

Conclusion

Caching in Next.js isn't about "caching as much as possible." It's about finding the balance between freshness and performance.

If your caching strategy still feels messy, try starting by separating data that's "okay to be stale" from data that "must be fresh."

A question for you all: How do you set up caching in Next.js these days? Do you rely more on time-based or on-demand revalidation?
