transformers, tensor.js, PyTorch and tRPC

dumb question: does anyone has experience with tensorflow.js? is there any major obstacle to use tensorflow.js rather than PyTorch and tensor? Just wondering if there could be any future difficulty using t3 stack while having transformers and embedding models to generate output at the backend

`QueryClientProvider` not included in `withTRPC`?

Trying to use import { useIsMutating } from "react-query" but it's throwing Error: No QueryClient set, use QueryClientProvider to set one We have the trpc.withTRPC(MyApp) with Next.js to add the tRPC provider - expected that this wouldn't also add the QueryClientProvider?...

Handle React error boundary

Seems like Im doing something wrong as I can't handle the error boundary from trpc query. I've queryClient with useErrorboundary set to true and wrapped my component that uses trpc query with the React Error Boundary but it doesn't seem to be able to catch it. When I just throw before the query it successfully intercepts the error but from trpc seems its not doing that? Am I doing something wrong ?? ```js const [queryClient] = useState(...

Any tips for Typescript slowness?

We successfully migrated from 9.x to 10 but are still seeing slow VS Code perf (10+ seconds to get any type info) are there any strategies we can use to minimize this?

Is it possible to call one procedure in another?

I have multiple routers in my trpc server. For example userRouter (e.g. procedure: getUser) and postRouter (e.g. procedure: updatePost). Is it possible to call the getUser procedure from my userRouter in my updatePost procedure? Or are all procedure effectively independent....

Handling Query Errors at Root of App (v9)

I want to show an error toast on my NextJS frontend every time there is an error from useQuery in a functional component. Is there a way to add something at the root of my app that can watch for trpc errors or do I have to handle it at every use of useQuery? (note: i am on v9)

trpc hook pattern. This works, but I’m not convinced…

I want to call my route when a button is clicked and have access to isLoading, onError etc… I have implemented a pattern using ‘’refetch()’’ but it doesn’t feel ‘correct’ is there a better way of doing this.

Why do some examples create PrismaClient in context, and others don’t

Is there a specific reason to do this or not to do this? I can imagine with the new Prisma extension feature you could do some handy things like attaching multi tenancy data to each query beforehand
