🚀 Quick Setup

After choosing your combination, follow these steps:

Step 1: Start Frontend

# Example with Vue
git clone https://github.com/halolight/halolight-vue.git
cd halolight-vue
pnpm install
pnpm dev

Step 2: Start Backend API

# Example with FastAPI
git clone https://github.com/halolight/halolight-api-python.git
cd halolight-api-python
pip install -e ".[dev]"
uvicorn app.main:app --reload

Step 3: Configure Frontend to Connect Backend

# Frontend project's .env.local
VITE_API_URL=http://localhost:8000/api
VITE_USE_MOCK=false  # Disable Mock, use real API
