"""
|
||||
Unified Single-Command Project Launcher for Brand Catalog Product LLM & RAG Intelligence Engine.
|
||||
|
||||
Usage:
|
||||
python run_project.py
|
||||
|
||||
What this script automates:
|
||||
1. Checks & launches PostgreSQL via Docker Compose (`docker compose up -d`).
|
||||
2. Starts FastAPI backend server on http://localhost:8000 (with background auto-seeding).
|
||||
3. Starts Vite frontend dev server on http://localhost:5173 (or serves static dist).
|
||||
4. Keeps both servers running concurrently with instant hot-reloading & single Ctrl+C exit.
