Composable Logic via Higher-Order Hook Interceptors

Higher-order hooks allow you to wrap existing hooks to inject cross-cutting concerns like analytics, logging, or performance tracking without modifying the original hook's logic.

snippet.js
javascript
const withAnalytics = (useHook: Function) => (args: any) => {
  const result = useHook(args);
  
  useEffect(() => {
    if (result.triggered) {
      Analytics.track('Action Performed', { ...args });
    }
  }, [result.triggered]);
 
  return result;
};
 
const useLoggedAuth = withAnalytics(useAuth);

react

Breakdown

const withAnalytics = (useHook) => (args) => ...

A factory function that returns a new hook, following the decorator pattern for hooks.

useEffect(() => { ... }, [result.triggered])

Intercepts internal hook state changes to perform secondary side-effects automatically.
