TODOS

• add default cache and use query integration tests
• add global sync default cache and use query integration tests
• variables as query keys.
• optimistic UI queries
• storage options -> session, cookie, indexdb etc…
• Performance optimizations like pagination and lazy loading data
• Deduping multiple requests for the same data into a single request
• refetchOnReconnect, refetchInterval
• retry mechanism
• structural sharing
• dependent queries

   let userId = null;
    useQuery(['user', email], getUserByEmail, {
     onSuccess: (user) => {
             userId = user.id;
         },
     })
    useQuery(['projects', userId], getProjectsByUser,
    {
         // The query will not execute until the userId exists
         enabled: !!userId,
     }
    )

• refetchInterval number | false
• refetchIntervalInBackground boolean
• refetchOnMount boolean
• refetchOnReconnect boolean

Fetching Indicators

• isLoading: indicates a hard state reload
• isFetching: indicates a background state reload, where initial data is still available through cache
