Best Practices for Optimizing Performance in Large-Scale MERN Apps

Body

Hey everyone ,
I am building a large-scale Mern project with multiple dynamic components and API calls.
I want to optimize performance, especially React Re-rendering and MongoDB query times.
What's the best structure or pattern you follow for handling complex state + DB queries in Real-time Dashboards?

Hypothetically I would go with TanStack Query for API caching, Zustand/Redux for global state, memoize heavy components, use WebSockets for real-time, and optimize MongoDB with indexes + Redis caching.
