Server-Side Caching Strategies
Learn to cache data on the server using `fetch` options and revalidation to improve performance.
Why Server-Side Caching?
In Next.js, server-side caching is crucial for building fast and efficient web applications. It helps reduce load times and server strain.
- Performance: Delivers content faster to users.
- Cost Reduction: Less frequent data fetches mean fewer API calls, potentially saving money.
- Scalability: Handles more users without overloading your backend.
We'll explore how Next.js leverages the native fetch API for powerful caching.
Next.js `fetch` & Caching Defaults
When you use the native fetch API in Next.js Server Components, it automatically caches data by default. This is like having a built-in data store.
By default, fetch requests are cached using the 'force-cache' strategy. This means Next.js will look for a cached response first and use it if available, only fetching new data if no cache entry exists.
