Writing Resilient Components

Principle 1: Don’t stop the data flow

• Don’t stop the data flow in rendering.
• Read the props directly in your component and avoid copying props (or anything computed from the props) into state.
• Use useMemo to memoize expensive computations.
• Don’t stop the data flow in side effects.
• Use useEffect to track side effect dependencies.
• Don’t stop the data flow in optimizations.
• With useCallback and useContext, you can avoid passing functions deep down altogether. This lets you optimize rendering without worrying about functions.

Principle 2: Always be ready for render

• Component shouldn’t break just because it or its parent re-renders more often

Principle 3: No Component Is a Singleton

• Even if a component is rendered just once, your design will improve if rendering twice doesn’t break it.

Principle 4: Keep the Local State Isolated

• Think about which state is local to a particular UI representation — and don’t hoist that state higher than necessary.
