App, API aur Database — teeno ek repo mein, aur connected ✅
Episode 2 mein hum PlanIt ka poora project setup karte hain: React Native app, Node.js + TypeScript + Express server, aur PostgreSQL — aur ek GET /health endpoint jo prove karta hai ki database connected hai.

Stack: React Native · TypeScript · Node.js · Express · PostgreSQL

✅ Is episode mein:
– Monorepo folder structure (apps/PlanItMobile, server, docs)
– package.json scripts + TypeScript config (tsconfig)
– .env aur DATABASE_URL setup
– Express server with GET /health
– PostgreSQL role, database aur connection (psql)
– Real errors aur unka fix — “already exists”, syntax errors
– Proof: 200 OK → “database”: “connected”
