cleanup function #5

Closed musicformellons closed 3 years ago

musicformellons commented 3 years ago

I am using code very similar to this codepen, but when I login using an axios call I get this warning:

index.js:1 Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.
    at Login (http://localhost:3000/static/js/main.chunk.js:2036:67)
    at Route (http://localhost:3000/static/js/vendors~main.chunk.js:55437:29)

Probably I should cleanup my axios call somehow, but I do not really have clue how to do that?! Tried, but no success so far. I think the useEffect must be in the library as it is not in my code?!

Indeed needed to take care of cancellation of Axios in the loginFn, then warning was gone.
