Overview

Advanced hook patterns enable complex, reusable logic. Learn to compose hooks effectively and build hook libraries.

Composing Hooks

Build complex functionality by composing simpler hooks together. This creates powerful, reusable abstractions.

Code Example:
// Base hooks
function useCounter(initial = 0) {
  const [count, setCount] = useState(initial);
  const increment = () => setCount(c => c + 1);
  return [count, increment];
}

function useLocalStorage(key, initial) {
  const [value, setValue] = useState(() => {
    const stored = localStorage.getItem(key);
    return stored ? JSON.parse(stored) : initial;
  });
  // ... implementation
  return [value, setValue];
}

// Composed hook
function useCounterWithStorage(key, initial = 0) {
  const [count, setCount] = useLocalStorage(key, initial);
  const increment = useCallback(() => {
    setCount(c => c + 1);
  }, [setCount]);
  
  return [count, increment];
}

Compose simpler hooks to build complex functionality. This pattern creates maintainable, testable abstractions.

Conclusion

Hook composition is a powerful pattern for building complex, maintainable logic.
