State Management Basics

State management gets complicated when too many parts of the app try to own the same information. A good approach starts with the simplest thing that works.

Keep State Local First

If a value only matters to one component or one small area of the UI, keep it there.

Lift State When Needed

Move state up only when siblings or parents genuinely need to share it.

Avoid Premature Abstraction

Not every app needs a store, and not every state update needs middleware. Add structure when the problem actually calls for it.

Separate UI From Business Rules

Try to keep interaction details away from the rules that determine the state itself.

Watch for Duplication

If the same data is being copied into several places, it is a sign that the ownership model needs attention.

Closing Thought

Simple state usually lasts longer than clever state. Start small, then add structure only when the UI proves it needs more.
