Nitro Backend Conventions

Overview

Backend TypeScript organized by business domain, with maximum type-safety via ts-brand and Zod validation. Business logic lives in namespaces, business errors are string literals (as const), and routes are minimal orchestrators.

Stack: Nitro (H3), TypeScript strict, Bun, Biome, ts-brand, ts-pattern, Zod.

1. Domain Structure

Each business domain is a folder with 3 files. Technical folders (routes/, middleware/, plugins/, config/) are separate.
