Disable trpc route cahce?

import { protectedProcedure, router } from "@/lib/trpc/server/trpc";
import { TRPCError } from "@trpc/server";

export const clientRouter = router({
get: protectedProcedure.query(async ({ ctx }) => {
const { id: user_id } = ctx.session.user!;

if (!user_id)
throw new TRPCError({
code: "NOT_FOUND",
message: "No user session found",
});

let { data: client, error } = await ctx.supabase
.from("clients")
.select("*")
.eq("user_id", user_id)
.single();

if (error) {
throw new TRPCError({
code: "BAD_REQUEST",
message: error.message,
});
}

return client;
}),
});
import { protectedProcedure, router } from "@/lib/trpc/server/trpc";

export const clientRouter = router({

message: error.message,
});
}

return client;
}),
});
I have this code to fetch some data from my db and return it, however if i call the endpoint again, the data is the same even if the db is different? Does trpc cache the old data on new request? If so i dont want this

However when i go to http://localhost:3000/api/trpc/getClient and test i get the fresh data on every request?

this is because of react-query’s caching if you set cacheTime to 0 in your useQuery call options, it won’t cache the response

but im using
export const trpc = experimental_createTRPCNextAppDirServer<AppRouter>({
config() {
return {
transformer: superjson,
links: [
loggerLink({
enabled: () => process.env.NODE_ENV === "development",
}),
experimental_nextHttpLink({
batch: true,
url: getUrl(),
headers() {
return {
cookie: cookies().toString(),
"x-trpc-source": "rsc-http",
};
},
}),
],
};
},
});
export const trpc = experimental_createTRPCNextAppDirServer<AppRouter>({
config() {
return {
transformer: superjson,
links: [
loggerLink({
enabled: () => process.env.NODE_ENV === "development",
}),
experimental_nextHttpLink({
batch: true,
url: getUrl(),
headers() {
return {
cookie: cookies().toString(),
"x-trpc-source": "rsc-http",
};
},
}),
],
};
},
});
The Nextjs server trpc so it only has the query method on it

The ”new”, experimental, nextHttpLink does set cache tags, so that’s why you’re seeing that behavior, it’s expected. You can set a revalidation time on how long you want the fetch request to be cached for in the link options, or just use the old/normal httpLink/httpBatchLink if you dont want any caching
