Start local with useState, move to Context for low-frequency environment settings, use React Query for server data, and reach for a global store like Zustand or Redux only when you have complex, high-frequency client logic.

Prop drilling occurs when you pass data through multiple layers of intermediate components that do not actually use the data, acting only as "mailmen" to deliver it to a deeply nested child. A common "Rule of Three" suggests that if you are passing a prop through more than three levels—especially if the middle components are indifferent to that data—it is a red flag. At this point, you should consider using React Context or a state management library to "teleport" the data directly to where it is needed.
Context is primarily a transport system rather than a storage system; it moves data from point A to point B but still requires local state (like useState) to manage that data. It is best suited for low-frequency "environment" data such as themes, language settings, or authenticated user info. In contrast, libraries like Redux or Zustand are designed for complex "business" data and high-frequency updates. They offer better performance optimizations, such as selectors, which prevent unnecessary re-renders when only a small portion of the global state changes.
When a value in a Context Provider changes, every component "consuming" that context is forced to re-render. If you store data that updates rapidly—like a timer, a real-time chat feed, or a "God Object" containing all app data—you trigger a "render cascade" that can make the application feel laggy or stuttery. To mitigate this, developers should split contexts into smaller, focused pieces and use useMemo to ensure that the context value only changes its referential identity when the underlying data actually updates.
Modern React architecture often separates "server state" from "client state." For data fetched from an API, tools like React Query are recommended because they handle complex logic like caching, loading states, error handling, and re-fetching automatically. This often replaces about 80 percent of what developers used to put into global stores like Redux, leaving those libraries to handle only "browser-born" logic like complex form wizards or global UI settings.
"Provider Soup" happens when your root component is wrapped in a dozen different Context Providers, making the code difficult to read. You can clean this up by using "composition"—creating a single AppProvider component that wraps all your individual providers in one place. Additionally, you should evaluate if multiple contexts can be consolidated into a single organized store, such as a Zustand store, which can manage multiple pieces of state without requiring nested providers.
