Question 1

How do I create a countdown timer with use-timer in React?

Accepted Answer

Set timerType to 'DECREMENTAL', define an endTime, and use the onTimeOver callback for actions when the timer reaches zero. The hook manages the countdown logic automatically, as shown in the decremental timer example.

Question 2

use-timer vs using setInterval directly: which is better for React apps?

Accepted Answer

use-timer abstracts setInterval management, providing built-in state and callbacks, reducing boilerplate and potential bugs. However, for very simple or one-off timers, direct setInterval might suffice with more manual control.

Question 3

Can I use use-timer for a Pomodoro timer application?

Accepted Answer

Yes, by configuring decremental timers for work intervals and using callbacks to switch between sessions. However, you'll need to handle session logic externally as use-timer doesn't support timer chains or advanced scheduling.

Question 4

How to handle multiple timers with use-timer in a single component?

Accepted Answer

Call the useTimer hook multiple times with different configurations. For synchronization, manage state externally, as use-timer doesn't provide built-in coordination between timer instances.

Question 5

Does use-timer work with server-side rendering (SSR) in Next.js?

Accepted Answer

The README doesn't specify SSR compatibility. Since it uses React hooks, ensure it's only called on the client-side to avoid hydration errors, possibly using dynamic imports or useEffect checks.

Question 6

How to reset a timer to its initial time after it has run?

Accepted Answer

Use the reset method provided by the hook, which stops the timer and sets time back to initialTime. This is shown in the basic usage example with the reset button for quick UI updates.
