return type of a query endpoint

Sorry, I just saw these messages. At the moment I mainly use refetch to update the response once something has been updated/deleted. I should probably just return the updated document in the response to the mutation, or in the case of a delete just remove it from the original data list. Would be more efficient for sure.

TRPC ratelimiting endpoints

Hmm, yes okay. I see what you are saying. This depends on vercel runs nextjs api endpoints, im not entirely sure. For now, this is working just fine. But I should look into this just encase. Thank you very much for the help 🙂

TRPC ratelimiting endpoints

But just so I understand, why does this solution not scale? You say I may have to deal with the promise in redis? Why is using memo not okay?

TRPC ratelimiting endpoints

Hi, thank you for the response. But I'm not sure I follow. Since this is hosted on serverless infrastructure (vercel), I don't think this is possible to use a in memory cache to stop this from happening? I may be misunderstanding your solution though.

TRPC ratelimiting endpoints

function which needs to be ratelimited (using the redis cache)

export const getUserGuilds = async (
  session: Session
): Promise<CachedUserGuild[] | null> => {
  if (!session.user.accessToken || !session.user.id) return null;

  const webUser = await cache.webUsers.get(session.user.id);
  if (webUser) return webUser.guilds;

  const response = await fetch(discord...)
  const guilds = await response.json();
  if (!response.ok || guilds.length <= 0) return null;
  
  // add guilds to cache
  await cache.webUsers.create(session.user.id, guilds);

  return guilds;
};

export const getUserGuilds = async (
  session: Session
): Promise<CachedUserGuild[] | null> => {
  if (!session.user.accessToken || !session.user.id) return null;

  const webUser = await cache.webUsers.get(session.user.id);
  if (webUser) return webUser.guilds;

  const response = await fetch(discord...)
  const guilds = await response.json();
  if (!response.ok || guilds.length <= 0) return null;
  
  // add guilds to cache
  await cache.webUsers.create(session.user.id, guilds);

  return guilds;
};

A big band aid fix would be to just add an artificial wait:

    if (!guilds) {
      await new Promise((resolve) => setTimeout(resolve, 1000));
      webUser = await cache.webUsers.get(ctx.session.user.id);
      guilds = webUser?.guilds;
      if (!guilds) {
        throw new TRPCError({ code: 'UNAUTHORIZED' });
      }
    }

    if (!guilds) {
      await new Promise((resolve) => setTimeout(resolve, 1000));
      webUser = await cache.webUsers.get(ctx.session.user.id);
      guilds = webUser?.guilds;
      if (!guilds) {
        throw new TRPCError({ code: 'UNAUTHORIZED' });
      }
    }

But obviously this is not very elegant..

trpc auto refreshes page when I lose focus

Hi. Thank you 🙂 I have found refetchOnWindowFocus which is what I am looking for. Here is my fix for any future people.

export const api = createTRPCNext<AppRouter>({
  config() {
    return {
      transformer: superjson,
      queryClientConfig: {
        defaultOptions: {
          queries: {
            refetchOnWindowFocus: false,
          },
        },
      },

export const api = createTRPCNext<AppRouter>({
  config() {
    return {
      transformer: superjson,
      queryClientConfig: {
        defaultOptions: {
          queries: {
            refetchOnWindowFocus: false,
          },
        },
      },

Awesome! I'm having a look into redis as we speak. Never used it before though, we'll see what happens!

I like your z_user_schema.parse(data.data); function. Very useful.

trpc query running twice

Technically, i could make it so the queries only run once in dev. But, this feature is enabled by default for a reason. Also, doing that is just a band aid fix. What if the user refreshes the page twice? Then my app breaks for a few second and the user gets greeted with a error page. Even though they have already recieved the data from the first request.
