React Hook Generator
Scaffold a custom React hook from a library of real patterns — toggle, localStorage, media query, debounced value, click-outside, fetch, event listener, interval and more — in JS or TS, SSR-safe, with a usage example and an optional test.
What this tool does
It writes a complete, working custom hook from a chosen pattern — not a stub. Each template is a real implementation you can drop in and use immediately.
Patterns
State helpers (useToggle, useBoolean,
useCounter, usePrevious), storage and
environment (useLocalStorage, useMediaQuery,
useWindowSize), timing (useDebounce,
useInterval, useTimeout), DOM
(useEventListener, useClickOutside,
useHover, useKeyPress), utilities
(useCopyToClipboard, useIsMounted), and data
(useAsync, useFetch).
Options
JavaScript or TypeScript (with generics and typed returns), an
SSR-safe typeof window guard for hooks that touch the
browser, a JSDoc block, and a companion React Testing Library test
using renderHook.
Usage example
Every hook comes with a short component snippet showing how to call it — switch to the "usage" tab.
