React useCountdown Hook
React useCountdown hook with start, stop, reset controls. Configurable interval, direction, and stop value. TypeScript ready.
Build countdown timers, flash sale clocks, or session timeouts in React. useCountdown returns the current count plus startCountdown, stopCountdown, and resetCountdown controls. Configure start/stop values, interval speed (default 1000ms), and direction (count up or down). All callbacks are memoized. Auto-stops when reaching target. SSR safe with no window access until started. Perfect for Next.js App Router, product launches, quiz timers, or any time-limited UI.
