SSE streaming added unnecessary complexity and latency due to buffering issues across Node.js event loop, Nginx proxy, and Docker layers.

Tech stack
| Layer | Choice | Rationale |
|---|---|---|
| Backend | Express + TypeScript | Simple, well-known, sufficient for a small local app |
| Frontend | React + Vite + TS | Fast dev experience, modern tooling |
| Database | PostgreSQL | Deployed on Synology NAS |
| Migrations | Knex | Lightweight, SQL-close, supports seeds |
| Shared | Pure TypeScript types | Zero-runtime, imported by both backend and frontend |
Prerequisites
- Node.js >= 20
- PostgreSQL >= 15
- npm >= 10
Getting started
# Install all workspace dependencies
npm install
# Build shared types (must be done before backend/frontend)
npm run build -w shared
