Summary of Changes

Hello @unnoq, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a compatibility issue with trpc^11.10 by updating the @trpc/server dependency and introducing a necessary batchIndex property to procedure calls. These changes ensure that the orpc package functions correctly with the newer tRPC version, preventing potential errors related to missing context properties during procedure execution.

Highlights

Dependency Update: Updated the @trpc/server dependency from ^11.9.0 to ^11.10.0 in packages/trpc/package.json.
tRPC Procedure Context Fix: Added the batchIndex: 0 property to the context object passed to toORPCProcedure in packages/trpc/src/to-orpc-router.ts to ensure compatibility with trpc^11.10 procedure calls.

Changelog

packages/trpc/package.json
- Updated @trpc/server dependency to ^11.10.0.
packages/trpc/src/to-orpc-router.ts
- Added batchIndex: 0 to the ORPCProcedure context object.

🐰 A tiny zero hopping through the code,
batchIndex set where inputs flowed,
a version bumped, a quiet tune,
small change by the light of the moon,
carrots celebrated — hop, behold! 🥕✨

Code Review

This pull request updates the @trpc/server dependency to ^11.10.0 and adds the newly required batchIndex property to tRPC procedure calls. While this fixes the immediate issue caused by the dependency update, the implementation of hardcoding batchIndex: 0 is not robust and can lead to incorrect behavior in batched requests. My review includes a suggestion for a more resilient approach that prepares for a proper fix by propagating the batch index through the request context.
