how to build tRPC and Prisma with express?
I am using TSC as the official docs example does.
But when I use paths in tsconfig.json, It does not work because of not transforming paths . Should I add webpack like nestjs doing?...
How to infer types from input?

trpc + AWS Lambda (through cdk)
Hi all, has anyone successfully integrated tRPC with AWS Lambda? My current stack is API Gateway + Lambda, all created through cdk. I am trying to figure out how to hook up the tRPC router and client to the lambda code. This is my first time using tRPC 😅
Is it possible to narrow an output schema if the query optionally doesn't return all fields?
I have a router procedure that has an input schema that has an optional
filter that changes the shape of the data to only include those fields (like sql select), but those records will fail the output schema which contains all of the fields as required. is there a way to construct a .output() specification that narrows the type, possibly using z.partial() so that these partial "rows" will pass output validation?Fetching different server url than defined in config
Is it possible to access the reactQuery instance and fetch different server url? I would like to use reactQuery to get data from my server which is at say
/address-middleware instead of hitting /trpc/.... Can I do that? I dont want to setup separate reactquery provider or something just to call one separate endpointError types in catch block
Hey!
I have a mutation that I want to catch if the procedure throws an error, I'd like to get the code of the error ("UNAUTHORIZED", "FORBIDDEN" etc.) but TRCPClientError doesn't have full types (basically I can't access the code property). I saw a generic that you can pass to the error but I don't know what to pass as the generic to get the types.

Issue with monorepo architecture ant tRPC
Hi, we had an issue with batched requests that if we batch some requests they produce a TRPCClientError which says
Cannot read properties of undefined (reading 'messsage') so I have read that at least error problem was fixed in newer versions, so we tried to update version, but then the builds started to fail. We get this error (photos in the thread) and more information
Using tRPC in CRON jobs
Hey everyone, this might be a very stupid question, but is it possible to use tRPC inside a CRON job? I saw that Vercel now supports them, and since I use tRPC inside a NextJS project, I thought that it could be used. Unfortunately, I wasn't able to find anything online.
async createContext for Express Adapter
Been debugging an odd behavior for the past hour, it seems like that an async function does not work in the express adapter. Is that supposed to work or is that the expected behavior? If this is a bug i can toss together a quick sandbox, but figured I check first whether this is expected or not.
If this is expected behavior, should the async calls happen in middleware instead? Seems a bit at odds. Thoughts?...
Is it possible to split the router definition with the imlementation?
I want to define the server router(input\output\meta) in a separate package from the server package
I want to have a package that will contain the types I use + the router definition, another for the server itself(will use the router definition like an interface),
and lastly the client package which ill only need to import the types package to work
is this possible?...

JSON inferred router output not matching
Hello. I have a procedure query which is returning Json from a postgresql db using Prisma. The type in the query on the server is showing up as
JsonValue (definitions below).
The inferred type from the router.procedure.query() on a createTRPCProxyClient instance comes back as expected, but the type definition using inferRouterOutputs<AppRouter> types the Json data as string | null.
Any ideas? Thanks. New to tRPC so sorry if this is a no-brainer....Best way to implement input based validation on a router procedure
Hi guys, bit of a noob. I have already created a 'protectedProcedure', ensuring the user is logged in, but for some of my procedures, I also want to ensure the user is an ADMIN for the account specified on the input. This is my first try with validation just added at the top of the procedure implementation...
```
changeUserAccessWithinAccount: protectedProcedure
.input(z.object({ user_id: z.number(), account_id: z.number(), access: z.enum([ACCOUNT_ACCESS.ADMIN, ACCOUNT_ACCESS.OWNER, ACCOUNT_ACCESS.READ_ONLY, ACCOUNT_ACCESS.READ_WRITE]) }))
.query(async ({ ctx, input }) => {...
