# @repo/api — tRPC Router Definitions

tRPC routers that call controllers from `@repo/core`. Each procedure validates input and delegates to a controller.

## Rules

- NEVER put business logic in routers — delegate to controllers
- Input validation uses Zod schemas
- Each domain gets its own router file

## Adding a New tRPC Router

1. Create `src/router/{domain}.router.ts`
2. Import `router` and `publicProcedure` from `../trpc.js`
3. Define procedures (`.query()` for reads, `.mutation()` for writes)
4. Each procedure calls a controller from `@repo/core`
5. Add router to root `appRouter` in `src/router/index.ts`
