How to do state management on the server side of Next.js
In Next.js 15, managing server-side state is simpler and more powerful thanks to React Server Components and the App Router. You can fetch data directly in server components, store session-like state using middleware or cookies, or persist data with databases and cache layers like Redis or Upstash. For interactive UI, client components can be hydrated with server-fetched props. And for clean, shareable state management, URL query parameters let you control things like tabs, filters, or pagination—no client libraries needed. This approach reduces reliance on global state tools and enhances deep linking and user experience.
