All my mutations are failing due to an empty body after upgrading to 11.0.0-rc.362

TRPCError: JSON Parse error: Unexpected EOF\n    at new TRPCError (/mnt/c/Users/Ángel/IdeaProjects/back/node_modules/.pnpm/@trpc+server@11.0.0-rc.362/node_modules/@trpc/server/dist/unstable-core-do-not-import/error/TRPCError.mjs:51:12)\n    at <anonymous> (/mnt/c/Users/Ángel/IdeaProjects/back/node_modules/.pnpm/@trpc+server@11.0.0-rc.362/node_modules/@trpc/server/dist/unstable-core-do-not-import/http/contentType.mjs:23:30)\n    at processTicksAndRejections (:12:39)

I have tried debugging in http/contentType.mjs and I found the request body is coming empty even if it shows a body on the browser devtools. Originally happened after upgrading a lot of rc.xxx versions at once but I pinpointed it on rc.362. The mutation works fine on rc.361 even using rc.364 on the client....

How to get data type from onMutate function in useMutation

I'm doing optimistic updates using the technique which is documented here https://tanstack.com/query/latest/docs/framework/react/guides/optimistic-updates . I found that I'm using the same queries in multiple spots and want to extract the update code so that I don't have to copy and paste. I can't figure out the type of the data parameter in the onMutate function. ``` api.task.createTask.useMutation({ onMutate: async (data) => {}})...

TRPClientError: Unexpected character

Hello, I am working on an Expo app and I seemingly randomly get the error in the picture. I don't really know why because I send many requests and sometimes it happens and sometimes not. I can provide any code that could be helpful. This the project repo: https://github.com/lmnek/run-app (I use npm and these packages ├── @trpc/client@11.0.0-rc.359 ├── @trpc/react-query@11.0.0-rc.359...

Solution:

Usually a sign that something between the client and the server isn’t working in the infrastructure

TRPC Docs Generation

Hey, I want to generate a swagger-like interface to document my TRPC api. However, I don't want to use trpc-openapi because I don't want to have to map the endpoints to be restful. I just want to directly generate docs for the rpc calls without converting it into openapi. I found a package that does exactly this, but now I can't find it again for the life of me. Would anyone know which package does this?

Is there a way to use TRPC React Query Integration with Nanostores instead of the Context API?

Currently we use TRPC by wrapping out application in a TRPC context provider. However, in some use cases, such as an Astro App, we don't want to wrap our entire app in a React Context. A common solution is to share state between Astro islands using nanostores (https://docs.astro.build/en/recipes/sharing-state/). I wanted to know if there is any way to share the TRPCReact client between Astro components using nano stores, without needing to use a React Context Provider. We can already share the React Query client between components using nanostores by passing the client as a parameter to the useQuery function. However, I could not find an option to pass the trpc client in the same way. I would greatly appreciate any help on this....

What do you guys think about the approach of importing/exporting tRPC types to be used in separate B

Hello, I was looking for a way to share tRPC API between multiple electron apps, I thought first about using a Nx monorepo but it turned out it's almost impossible to make it work with electron app that use electron-vite. After more research I found this repo: https://github.com/mkosir/trpc-api-boilerplate...
