tRPC httpBatchLink expired credential enforcement Goal: determine whether an expired credential should fail only the affected procedure in a tRPC batch or invalidate the entire HTTP batch, and where credential validation belongs in the middleware chain. tRPC has no native authentication, session, or credential-expiry feature, so access control lives in userl
The experimental_defer feature in tRPC v10 allows for the deferral of query execution to optimize initial page loads by delaying specific data fetching until the component mounts. Current documentation indicates that this functionality is designed to work with standard useQuery hooks. However, there is a known gap regarding its interaction with useSuspenseQu
Goal We want to rely on tRPC v10’s Zod‑auto‑inference to provide fully typed end‑to‑end calls without manual type annotations, especially when procedures return objects that contain optional properties or default values defined in the Zod schema. Constraints & Uncertainty The auto‑inferred output type is generated from the Zod schema used for the procedu
Integration Goal Determine whether tRPC should expose a user‑configurable hook for the underlying HTTP Agent (or undici fetch pool) while preserving the generic client abstraction that works across Node.js versions. The challenge lies in balancing backward compatibility, version‑specific defaults (legacy http.Agent vs undici), and ensuring that any Agent rep
Procedure not found error when invoking unregistered tRPC procedure The goal is to maintain synchronization between client-generated procedure calls and server router definitions so that the tRPC runtime never returns a procedure‑not‑found failure, while operating a low‑traffic API where connection overhead and resource usage are concerns. Constraints includ
Goal: Use tRPC’s httpBatchLink to coalesce multiple client queries into a single POST request while running on a serverless production platform. Constraint: Locally, a long-running Node process accepts the combined payload without issue. On serverless or edge hosts, provider-specific body size limits and cold-start timeouts can cause the entire batch to fail
Goal Ensure the tRPC‑generated client bundle stays within the size limits that keep Cloudflare Worker cold‑start latency under 50 ms for low‑traffic workloads. Constraints / uncertainty The generated client includes all procedure types, Zod validation schemas, and any procedural middleware. Its exact size depends on the number of procedures, schema complexit
