Implementation Examples

TanStack Query - Advanced Caching

import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';

// Custom hook for user data
function useUser(userId: string) {
  return useQuery({
    queryKey: ['user', userId],
    queryFn: () => fetchUser(userId),
    staleTime: 5 * 60 * 1000, // 5 minutes
    gcTime: 10 * 60 * 1000, // 10 minutes
    retry: 3,
    retryDelay: (attemptIndex) => Math.min(1000 * 2 ** attemptIndex, 30000),
  });
}

// Custom hook for user mutations
function useUpdateUser() {
  const queryClient = useQueryClient();
  
  return useMutation({
    mutationFn: updateUser,
    onMutate: async (newUser) => {
      // Cancel outgoing refetches
      await queryClient.cancelQueries({ queryKey: ['user', newUser.id] });
      
      // Snapshot previous value
      const previousUser = queryClient.getQueryData(['user', newUser.id]);
      
      // Optimistically update
      queryClient.setQueryData(['user', newUser.id], newUser);
      
      return { previousUser };
    },
    onError: (err, newUser, context) => {
      // Rollback on error
      queryClient.setQueryData(['user', newUser.id], context?.previousUser);
    },
    onSettled: (newUser) => {
      // Always refetch after error or success
      queryClient.invalidateQueries({ queryKey: ['user', newUser.id] });
    },
  });
}

SWR - Simple but Effective

import useSWR, { SWRConfig } from 'swr';

// Global configuration
function App() {
  return (
    <SWRConfig
      value={{
        fetcher: (url) => fetch(url).then((res) => res.json()),
        revalidateOnFocus: false,
        revalidateOnReconnect: true,
        dedupingInterval: 2000,
      }}
    >
      <UserProfile userId="123" />
    </SWRConfig>
  );
}

// Custom hook with error handling
function useUserWithError(userId: string) {
  const { data, error, isLoading, mutate } = useSWR(
    userId ? `/api/users/${userId}` : null,
    {
      onError: (err) => {
        console.error('Failed to fetch user:', err);
      },
      onSuccess: (data) => {
        console.log('User fetched successfully:', data);
      },
    }
  );

  return {
    user: data,
    isLoading,
    isError: error,
    refresh: mutate,
  };
}
