Middleware composition in tRPC can be verbose and error-prone; this Skill reduces boilerplate and prevents common pitfalls by showing how to authenticate, authorize, log, time, trace, and safely extend request context for server procedures.
Use the middlewares skill to create an authedProcedure that validates ctx.user, throws an UNAUTHORIZED TRPCError when missing, and returns opts.next with a narrowed ctx.user so downstream procedures see a non-nullable user.

To create tRPC middleware for authentication, validate the incoming context user and call opts.next() with a narrowed ctx to guarantee downstream procedures receive a non-nullable user object. This pattern safely extends the request context for authorized server procedures.
Compose reusable tRPC middleware chains by using .concat() to combine existing middleware and .unstable_pipe() to extend chains for ordered context enrichment. This approach reduces boilerplate and prevents common composition errors in server procedures.
Yes, tRPC v11 supports request timing and logging middleware for observability. You can implement middleware patterns to measure request duration and create integration points for OTEL tracing to avoid silent internal errors during procedure execution.
Runtime errors or security issues when extending ctx usually occur from incorrect typing or failing to properly return opts.next(). Explicitly call and return opts.next() with safe context extension typing to ensure correct middleware execution flow.
Yes, you can build an adminProcedure in tRPC that enforces role-based authorization by creating middleware to check user roles within the request context. This guarantees non-nullable user context and throws an UNAUTHORIZED TRPCError when permissions are insufficient.
