Next.jsのSSRで取得した値をTanStackQueryの仕組みで更新する

Next.js

TanStackQuery

ReactQuery

フロントエンド

app/layout.tsなどのSSRコンポーネントで、prefetchQueryを行い、dehydrateをproviderに渡す。

export default async function RootLayout({
  children,
}: {
  children: React.ReactNode;
}): Promise<JSX.Element> {
  let user: User | null = null;
  let userCategories: UserCategory[] = [];

  const accessToken = cookies().get('accessToken')?.value ?? '';

  if (accessToken) {
    const [userData, categoriesData] = await Promise.all([
      getMe(accessToken),
      getMeCategories(accessToken),
    ]);

    user = userData;
    userCategories = categoriesData;
  }

  const queryClient = new QueryClient();

  await Promise.all([
    queryClient.prefetchQuery({
      queryKey: [GET_ME_KEY],
      queryFn: async () => await Promise.resolve(user),
    }),
    queryClient.prefetchQuery({
      queryKey: [GET_ME_CATEGORIES_KEY],
      queryFn: async () => await Promise.resolve(userCategories),
    }),
  ]);

  return (
    <html lang='ja'>
      <body>
        <Providers dehydratedState={dehydrate(queryClient)}>
          {children}
        </Providers>
      </body>
    </html>
  );
}

HydrationBoundaryにdehydrateを登録する。

export const Providers = ({
  dehydratedState,
  children,
}: ProvidersProps): JSX.Element => {
  const [client] = useState(
    new QueryClient({
      defaultOptions: {
        queries: {
          staleTime: 5000,
          retry: false,
          refetchOnWindowFocus: false,
        },
        mutations: {
          retry: false,
        },
      },
    })
  );

  return (
    <QueryClientProvider client={client}>
      <HydrationBoundary state={dehydratedState}>
        <RecoilRoot>
          <ToastContainer />
          <Suspense fallback={<LinearLoading />}>{children}</Suspense>
        </RecoilRoot>
      </HydrationBoundary>
    </QueryClientProvider>
  );
};

更新したいタイミングでinvalidateQueriesを行い再取得する。

export const usePostMeMemo = (): UseMutationResult<
  boolean,
  fetch.FetchError,
  PostMeMemoRequest
> => {
  const queryClient = useQueryClient();

  return useMutation<boolean, fetch.FetchError, PostMeMemoRequest>({
    mutationFn: postMeMemo,
    onSuccess: () => {
      void queryClient.invalidateQueries({
        queryKey: [GET_ME_MEMOS_KEY],
      });

      void queryClient.invalidateQueries({
        queryKey: [GET_ME_CATEGORIES_KEY],
      });
    },
  });
};
