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";
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;
  }),
});

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

hmm idk about that one tbh, @julius ? app router master

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
