search bar causing infinite loop in React

 Programing Coderfunda     September 09, 2023     No comments   

Here's parent component: const Page = () => { const { user } = useAuth(); const router = useRouter(); const [allUsers, setAllUsers] = useState([]); const [search, useSearch] = useState(""); useEffect( () => { if (user !== null && user.isAdmin) { const token = localStorage.getItem("token"); api .get("/users", { headers: { authorization: `Bearer ${token}`, }, }) .then((data) => { setAllUsers(data.data); }) .catch((error) => { if (error.message === "Request failed with status code 401") { const refresh_token = localStorage.getItem("refresh_token"); const refresh = api .post("/auth/refresh", { refresh_token, }) .then((req) => { if (refresh.data.token && refresh.data.refresh_token) { localStorage.setItem("token", refresh.data.token); localStorage.setItem( "refresh_token", refresh.data.refresh_token ); api .get("/users", { headers: { authorization: `Bearer ${refresh.data.token}`, }, }) .then((req) => { setAllUsers(req.data); }); } }) .catch((error) => { if (error.message === "Request failed with status code 400") { if (error.response.data.message === "Refresh Token não encontrado." ) { router.push("/"); } } }); } }); } else if (!user) { router.push("/404"); } else { router.push("/auth/login"); } }, [user, router] ); useEffect( () => { const filterSearch = () => { if (search === "") return allUsers; return allUsers.filter((user) => user._id.includes(search)); }; const filtered = filterSearch(search); setAllUsers(filtered); }, [search, allUsers], search ); const useConsultasPagination = (data, page, rowsPerPage) => { return useMemo(() => { return applyPagination(data, page, rowsPerPage); }, [data, page, rowsPerPage]); }; const [page, setPage] = useState(0); const [rowsPerPage, setRowsPerPage] = useState(5); const keys = useConsultasPagination(allUsers, page, rowsPerPage); const handlePageChange = useCallback((event, value) => { setPage(value); }, []); const handleRowsPerPageChange = useCallback((event) => { setRowsPerPage(event.target.value); }, []); if (user !== null && user.isAdmin) { return ( Search | API Users ); } else { router.push("/404"); } } And here's search bar's component: export const UsersSearch = (props) => { const { setAllUsers = () => {}, allUsers = [], search = "", useSearch = () => {} } = props; const { user } = useAuth(); const router = useRouter(); const SetSearch = (value) => { useSearch(value); }; const HandleInputChange = (event) => { console.log('a') event.preventDefault(); const target = event.target; const value = target.value; if (value === "") { SetSearch("") } else { SetSearch(value); } }; if (user.isAdmin) { return ( ); } else { router.push("/404"); } }; The problem I'm facing is that, everytime a change the text in the search I get an infinite loop, although the search feature works (and when I remove all the text from the bar it doesn't comes back to the initial allUsers value). Help me please :) Changed the useEffect from causing another loop
