Introduction
Build scalable Nextjs applications using architectural patterns. Focus on data fetching and deployment. These patterns help you handle millions of users. Performance stays high.
Server Components and Client Components
Modern Nextjs applications use Server Components and Client Components.
Server Components
Server Components offer advantages.
- Zero client side JavaScript for static content.
- Direct database access.
- Automatic code splitting.
- Improved page load speed.
Client Components
Use Client Components for specific needs.
- Interactivity like clicks and changes.
- Browser APIs like local storage.
- State management.
- Effects for subscriptions.
Data Fetching Patterns
Parallel Data Fetching
Fetch data in parallel to save time. This method runs requests at the same time.
Streaming and Suspense
Use Streaming with Suspense for a better experience. Show loading states while components finish.
Caching Strategies
Nextjs has several caching layers.
- Request Memoization: Deduplicates identical requests.
- Data Cache: Stores fetch requests.
- Full Route Cache: Pre renders routes.
- Router Cache: Stores navigations on the client.
Cache Revalidation
Use time based or on demand revalidation. Update your data on a schedule or when needed.
Key Learnings
- Start with Server Components. Use Client Components sparingly.
- Fetch data in parallel.
- Use caching strategies.
- Use Suspense for progressive loading.
These patterns prepare your application for millions of users.
