LibraryAPI

This project is a test web application built using FastAPI, a modern web framework for creating APIs in Python. It showcases the use of Pydantic for data validation, SQLModel for database interactions, Alembic for migration management, PostgreSQL as the database system, and Docker Compose for easy deployment.

Key Components:

1. FastAPI: Provides high performance and simplicity for developing RESTful APIs, supporting asynchronous operations and automatic documentation generation.
2. Pydantic: Used for data validation and serialization, allowing easy definition of data schemas.
3. SQLModel: Combines SQLAlchemy and Pydantic, enabling database operations with Python classes.
4. Alembic: A tool for managing database migrations, making it easy to track and apply changes to the database schema.
5. PostgreSQL: A reliable relational database used for data storage.
6. Docker Compose: Simplifies the deployment of the application and its dependencies in containers.

Installation Instructions

For development:

1. Clone the repository:

   git clone https://github.com/wowlikon/libraryapi.git
   

2. Navigate to the project directory:

   cd libraryapi
   

3. Configure environment variables:

   edit .env
   

4. Build the Docker containers:

   docker compose build
   

5. Run the application:

   docker compose up api
   

For make new migrations:

docker compose run --rm -T api alembic revision --autogenerate -m "Migration name"

For run tests:

docker compose up test
