This is a minimalist FastAPI backend designed to manage library records. It provides a RESTful interface and persists data using a PostgreSQL database.

Prerequisites

• Python 3.8+
• PostgreSQL

Configuration

The application uses environment variables for configuration. Create a file named .env in the root directory:

DATABASE_URL=postgresql://user:password@localhost:5432/library_db

Installation

Follow these steps to prepare your local environment:

1. Dependencies

Update pip and install the required packages:

python3 -m pip install --upgrade pip
pip install -r requirements.txt

2. Database Seeding

Initialize the PostgreSQL schema and populate the database with initial data:

python3 seed.py
