SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TRPC router development and wiring for server-side APIs can be error-prone without a clear blueprint. This guide provides a structured approach to building routers, procedures, and middleware with consistent patterns.

Core Features & Use Cases

Router structure & conventions: standardized file layout, middleware use, and type-safe procedures.
Context injection & error handling: guidance on injecting models into ctx and wrapping errors consistently.
Use Case: rapidly implement endpoints for domain-specific data access with zod validation and TRPCError handling.

Quick Start

Create or modify src/server/routers/lambda/<domain>.ts using the templates and samples to implement your API.

FAQPage Schema

How do I structure a tRPC router for server-side APIs?▼

Structure a tRPC router by defining domain-specific modules under a standardized file layout, using lambda-style routers to organize procedures and middleware for server-side APIs. This ensures consistent patterns and type safety across endpoints.

How does middleware work in tRPC routers?▼

Middleware in tRPC routers works by intercepting procedure calls to inject context, such as data models, and enforce consistent error handling before passing execution to the main procedure. This provides a structured approach for API request processing.

How do I add zod validation to tRPC procedures?▼

Add zod validation to tRPC procedures by defining zod schemas for your inputs and applying them to procedure definitions. This enforces type-safe inputs and ensures consistent error handling before the server-side API logic executes.

What is the best way to handle TRPCError in TypeScript routers?▼

The best way to handle TRPCError in TypeScript routers is by wrapping errors consistently within your procedures using standard tRPC error handling patterns. This ensures type-safe error responses across your server-side API endpoints.

Do I need TypeScript to use tRPC routers?▼

Yes, you need TypeScript to use tRPC routers effectively. Building and maintaining these server-side APIs requires TypeScript, tRPC, and zod to ensure type-safe inputs, context injection, and consistent error handling.

How do I inject models into tRPC context?▼

Inject models into tRPC context by defining a context creation function that passes required data models into the ctx object. This allows your procedures and middleware to access domain-specific data safely during API execution.
