# Backend for Glass Cutting Optimization

This directory contains the FastAPI backend application.

## Setup

1.  **Create a virtual environment:**
    ```bash
    python -m venv venv
    source venv/bin/activate  # On Windows use `venv\Scripts\activate`
    ```
2.  **Install dependencies:**
    ```bash
    pip install -r requirements.txt
    ```
3.  **Configure environment variables:**
    Create a `.env` file in this directory based on `.env.example` (you'll create this later).
4.  **Run database migrations (using Alembic):**
    ```bash
    # Initialize alembic (only once)
    # alembic init alembic

    # Edit alembic.ini and alembic/env.py to point to your models and database URL
    # ...

    # Create a migration
    # alembic revision --autogenerate -m "Initial migration"

    # Apply the migration
    # alembic upgrade head
    ```
5.  **Run the development server:**
    ```bash
    uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
    ```
