como usar componentDidmount no componente funcional
// passing an empty array as second argument triggers the callback in useEffect
// only after the initial render thus replicating `componentDidMount` lifecycle behaviour
useEffect(() => {
if(!props.fetched) {
props.fetchRules();
}
console.log('mount it!');
}, []);
// componentDidUpdate
useEffect({
your code here
})
// For componentDidUpdate
useEffect(() => {
// Your code here
}, [yourDependency]);
// For componentWillUnmount
useEffect(() => {
// componentWillUnmount
return () => {
// Your code here
}
}, [yourDependency]);
