Is it possible to get the procedure name / id in middleware?

I want to create a caching middleware that in some routes, stores a cache key that contains the route id (example: catalog.product.findMany) and the input (example: { categories: shirts }). It's not clear to me if this is possible.

Create client that is used in every request, without re-creating client

Hi all, Consider the following

export const createContextInner = async ({
  req,
  res,
}: {
  req?: Context['req']
  res?: Context['res']
}): Promise<Context> => {
  const app = await NestFactory.createApplicationContext(AppModule)
  return {
    app,
    prisma,
    req,
    res,
    supabaseServerClient: null,
    user: null,
  }
}

export const createContextInner = async ({
  req,
  res,
}: {
  req?: Context['req']
  res?: Context['res']
}): Promise<Context> => {
  const app = await NestFactory.createApplicationContext(AppModule)
  return {
    app,
    prisma,
    req,
    res,
    supabaseServerClient: null,
    user: null,
  }
}

This is annoying in local development because it needs to create the nest app for every request. The same thing with the prisma client. We'd like to create this once and use in every request. Is this possible?

Bug where 2 requests are fired at once. TRPC batches them. Can I cancel the 2nd via ProcedureOption?

Hey all. I have a bug where my app fires two identical requests at the same time. This happens do to some weird upstream auth listener logic. Ideally TRPC can help me mitigate this. I want to configure ProcedureOption such that it doesn't batch, but rather only lets the first request to go through. Is this possible?

const updatedCartItems = await trpcClient.user.cart.replaceCartOnAuthLoaded.mutate(
  {
    anonymousCartItems,
  },
  {
    onlyOneAtATime: true,
  },
)

const updatedCartItems = await trpcClient.user.cart.replaceCartOnAuthLoaded.mutate(
  {
    anonymousCartItems,
  },
  {
    onlyOneAtATime: true,
  },
)

How can I access ctx from inside of a procedure?

const appRouter = t.router({
  helloTab: t.procedure.input(z.object({ url: z.string().url() })).mutation(async ({ input, ctx }) => {
    //@ts-ignore
    const tab = ctx.sender.tab
    console.log(tab)
  }),
});

const appRouter = t.router({
  helloTab: t.procedure.input(z.object({ url: z.string().url() })).mutation(async ({ input, ctx }) => {
    //@ts-ignore
    const tab = ctx.sender.tab
    console.log(tab)
  }),
});

is something like this possible? Not working for me

Use TRPC function inside of a TRPC function

Hi all! We have a trpc query called getProduct. I want to use this getProduct query inside of another query (getCart query). Is this possible / simple as a single trpc request rather than multiple?
