useSuspenseQuery
There is no isLoading or isError in the return type of this hook. This is because <Suspense/>
and <ErrorBoundary/>
guarantee the data of this hook. Also, in the options of this hook, suspense is set to true by default. Any new options you need can be used like @tanstack/react-query's useQuery (opens in a new tab).
import { useSuspenseQuery } from '@suspensive/react-query'
const Example = () => {
const query = useSuspenseQuery({
queryKey,
queryFn,
}) // suspense: true is the default.
// No type narrowing required with isSuccess.
query.data // TData
}
motivation
You can use useQuery (opens in a new tab) with <Suspense/>
and <ErrorBoundary/>
by using the suspense option in @tanstack/react-query.
import { useQuery } from '@tanstack/react-query'
const Example = () => {
const query = useQuery({
queryKey,
queryFn,
suspense: true,
})
query.data // TData | undefined
if (query.isSuccess) {
query.data // TData
}
}
The return type of useQuery (query.data) will always be a success case thanks to this component's parents, <Suspense/>
and <ErrorBoundary/>
.
But @tanstack/react-query doesn't express this typescript typely.
That's why @suspensive/react-query provides useSuspenseQuery.
Focus on successful cases.
Now we can focus only on successful cases as fetching always succeeds inside our component.
