What are the limitations of the Context API?

While Context is powerful, it’s not perfect:

  • Re-render Performance: When a context value changes, all components consuming it will re-render, even if they don't care about the part that changed.
  • Not a replacement for a full-fledged state management library: Context is great for simple/global state, but for complex state logic (e.g., caching, middleware, side-effects), libraries like Redux, Zustand, or Recoil are more suitable.
  • Coupling components: Components become tightly coupled with the Context, which can reduce reusability.
  • Testing difficulty: Mocking Contexts during testing requires some extra setup.
