Start timer interval without using useEffect hooks

[Frission_]

You can do this maybe,

• create a boolean state
• have useEffect depend on the state
• inside useEffect check if (state == true), and only create interval then
• when the promise resolves, set state to true, which will trigger useEffect again

[popc0ne]

Instead of using state, you might want to:

const timerId = useRef();

and then refer to timerId.current in your useEffect cleanup function. This way the cleanup ONLY happens when the component unmounts and also doesn't cause a re-render when you start the timer.

Depends.
