Wmi reactjs ismounted hook with useeffect basic errors warning: cant perform a react state update on an unmounted component. this is a no op, but it indicates a memory leak in your application.
Useeffect Hook Reactjs To The New Blog I wrote this custom hook that can check if the component is mounted or not at the current time, useful if you have a long running operation and the component may be unmounted before it finishes and updates the ui state.

Custom hook that determines if the component is currently mounted. The warning "can't perform a react state update on an unmounted component" is caused when we try to update the state of an unmounted component. a straightforward way to get rid of the warning is to keep track of whether the component is mounted using an ismounted boolean in our useeffect hook. * use iscomponentmounted () to check if the component is currently mounted before performing certain actions. while the code is focused, press alt f1 for a menu of operations. Always check if a component is mounted before updating state or doing side effects. use the useeffect hook to manage component mount state and clean up side effects when a component unmounts. Okay pretty straight forward, now we have something we can call in place of useeffect which will pass the current status of the component, for you to evaluate inside (or outside if needed) of usestatuseffect. let's replace the useeffect example with this. enjoy!.
