unexpected message from server

Hi all, we see this error pretty randomly

error in connector: error querying the database: unexpected message from server

I try to replicate with the same query, but the error persists. Is this the kind of error wherein it makes sense to implement some kind of retry logic?

Which is more efficient: Promise.all([findUnique() * 3]) or prisma.$transaction([findUnique() * 3])?

With prisma, is it more efficient to do

await Promise.all([
  prisma.product.findMany()
  prisma.order.findMany()
  prisma.catalog.findFirst()
])

await Promise.all([
  prisma.product.findMany()
  prisma.order.findMany()
  prisma.catalog.findFirst()
])

await prisma.$transaction([
  prisma.product.findMany()
  prisma.order.findMany()
  prisma.catalog.findFirst()
])

await prisma.$transaction([
  prisma.product.findMany()
  prisma.order.findMany()
  prisma.catalog.findFirst()
])

Maybe transaction is slower because of transactional integrity? Or is there another command / alternative to $transaction that allows me to make just one trip to the database, rather than many? Ideally this is about optimizing efficiency/time/being better than Promise.all, and not about transactional integrity

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?

Deno Jupyter Notebook - monorepo support

Hi all! We have a typescript-based monorepo that uses Turbo/Pnpm/etc Our primary reason for coming across Deno is that it seems to be the best supported way to use Typescript in a Jupyter notebook. We'd like set up a notebooks/ subfolder in the apps/* folder of the project and do queries there I haven't been able to set this up (maybe due to inexperience with Deno). For example, both of the following commands fail:

// Importing from a package in node_modules
import { PrismaClient } from '@prisma/client';
// Importing from a monorepo package
import { soemthing } from '@myapp/api';

// Importing from a package in node_modules
import { PrismaClient } from '@prisma/client';
// Importing from a monorepo package
import { soemthing } from '@myapp/api';

I've tried both in the root of the project and in the notebooks/* sub-folder

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?
