Dealing with infinite loops with timers in useEffectBlogReact
December 10, 2018
In a project that I was using useEffect in I needed to setup an interval and a timeout.
The interval was used to occationally check for updates, while the timeout was used for auto play.
The problem turned out to be that it was firing the useEffect any time the component was rerendering, which resulted in more intervals being added. To fix this I passed in that I only wanted it to update based on a certain prop changed like seen at https://reactjs.org/docs/hooks-reference.html#conditionally-firing-an-effect.
