offline mode (expo app)
I have an expo (react native) app which uses better-auth, tRPC, hono router, mysql DB. Do I have any option to enable the 1 core feature of my app (daily emotion tracking) to work in offline mode (i.e. no network) and sync when network is connected?
Using react server components with separate API
Hi
I have a separate API from my frontend, when setting up https://trpc.io/docs/client/react/server-components how would I be able to have it use my separate API url instead...
Expo and nextjs TRPC issue
Hello,
I have a Nextjs project and an Expo mobile application that I am trying to use trpc between my native app and nextjs backend. When I try to fetch data from my mobile app, i get the following error:
[TRPCClientError: right operand of 'in' is not an object]...
Can we use trpc route inside another trpc route?
I have two routes, one is for generating image, and another one is uploading and creating a row in DB. So I am wondering if we can use the generating image route after the creating row in DB.
prefetchInfiniteQuery example?
Hi, I'm trying to switch to the newer tanstack react query pattern with our existing nextjs codebase, but I keep getting type errors when trying to use
queryClient.prefetchInfiniteQuery. I noticed there's no infiniteQueryOptions alternative to queryOptions on trpc.{aRouter}.{procedure}, so I'm assuming I have to configure queryOptions somehow to get it to take.
That's on the server, the situation is similar on the client. When I try to pass options to useInfiniteQuery I get the following error:
Type 'DefinedTRPCQueryOptionsOut<LedgerResponse, LedgerResponse, TRPCClientErrorLike<{ transformer: true; errorShape: DefaultErrorShape; }>, { keyPrefix: false; }>' is missing the following properties from type 'UseInfiniteQueryOptions<unknown, Error, InfiniteData<unknown, unknown>, readonly unknown[], unknown>': getNextPageParam, initialPageParam ts(2769)...Solution:
Nm, I see it's documented under the React Query Integration (classic). Must provide a cursor field to unlock the infinite properties. https://trpc.io/docs/client/react/useInfiniteQuery
react-native crashes with trpc > 11.3.0
Hey,
I am currently setting up trpc in our codebase. We have a monorepo with React webapp, Express.js API (node 20) and React-native mobile app (Expo 53). Once I add
"@trpc/client": "^11.7.2" as a dependency to the mobile app, it crashes on start immediately.
The logs show this error.

Hey! Might be being thick here but I'm implementing in an optimistic update layer and fully expected this to work:

Unauthorized Error while prefetching from protected procedure
I was working on a nextjs monorepo using trpc as backend I am integrating SSE with normal trpc methods, I implemented auth using better auth and it works very smoothly, but when I try to prefetch on server components I get not authenticated user error, but after render the app works without error. I checked further and reached upon conclusion that cookies aren't resolved because when I tried passing headers vis prop drilling from TRPC provider and using those in getting auth it worked and prefetching worked. Here is my problem, any help would be appreciated

migrated to trpc 11, pageprops not available after client side navigation
Before:
NextJs v14 pages router
Trpc v10
Now...
With infinite-query, how do I ensure a re-render during status=pending of next-page fetch?
Whether I use the
placeholderData option, or my Component's own custom skeletons=<number> prop, the fact is that I get either of those rendered only on the very first fetch (on page load).
When fetching a next data page, however, there simply is no rendering happening while .status === 'pending' and so no skeletons/placeholders show on the "Load more..." scenario.
Anyone know a solution to this, or an option for this I have somehow missed somewhere?...Hono tRPC Server body issue
I have been trying to get Cloudflare Workers, Hono and tRPC working for tens of hours now.
I am using the
@hono/trpc-server package which gives me middleware for trpc to run with hono. They even have an example with cloudflare workers and a d1 database, so I know it is possible to do what I am trying to do.
The problem I am having is that tRPC is not reading the body properly, or at all. Take this function as an example:

The AI SDK uses the Chat class as the abstraction that one is supposed to share: https://ai-sdk.dev/cookbook/next/use-shared-chat-context

Hey everyone! I’m pretty new to this way of building APIs. Is it possible to use tRPC to create type-safe APIs with Next.js (using React Query + prefetch) while having a separate Node.js backend inside the same monorepo?
authenticatedProcedure
Is it true that for every requests, it is going to call getSession()?
If yes, what is a good workaround or this is how everyone is doing?...
trpcClient
Is this way recommended or stable that we can save the trpcClient outside of the provider and access it easily? Like image 2
Type stable "combine" function for "useQueries"
Hey all,
im trying to use a https://tanstack.com/query/latest/docs/framework/react/reference/useQueries#combine function to combine the results from multiple queries together. As the documentation says, the combine function should be referentially stable.
Im trying to get this typed properly, but getting the proper type for the "result" parameter of the combine function is a little crazy the way I have it working now, see example below....
