How to fix missing dependency warning when using useEffect React Hook?

Question

With React 16.8.6 (it was good on previous version 16.8.3), I get this error when I attempt to prevent an infinite loop on a fetch request

./src/components/Bu         


        

Answer 1

const [mount, setMount] = useState(false)
const fetchBusinesses = () => { 
   //function defination
}
useEffect(() => {
   if(!mount) {
      setMount(true);
      fetchBusinesses();
   }
},[fetchBusinesses]);

This is solution is pretty simple and you don't need to override es-lint warnings. Just maintain a flag to check whether component is mounted or not.
