trpc query only once parameter is not null
New in T3 stack so forgive me if this is a noob question:
I am trying to run a trpc query only if a user is logged in. The user id is part of the query parameter.
const { data: sessionData } = useSession();
const cart = api.cart.getCart.useQuery({ userId: sessionData?.user?.id });
Normally I would just add sessionData to the query key but there is no option for that here right? Or is there?7 Replies
enabled in useQuery options @marvintherain
seems more like a protectedProcedure would make more sense here
I have found the options 🙂
const cart = api.cart.getCart.useQuery({ userId: sessionData?.user?.id },{queryKey: ["cart", "getCart", sessionData],});
The procedure is actually protected but it seemed inefficient to me to generate network requests destined to failuse the
enabled: !!sessionData optionUse the enabled option:
const { data: sessionData } = useSession();
const cart = api.cart.getCart.useQuery({ userId: sessionData?.user?.id }, { enabled: !!sessionData });why double call
just do protected procedure
thanks for your comments this helps a lot 👍
