This project serves as a demonstration of the seamless integration between FastAPI, SQLAlchemy, and Strawberry GraphQL, utilizing an SQLite3 database. It aims to showcase the synergy and capabilities of these technologies when combined.
-
FastAPI Integration: Utilizes FastAPI, a modern, fast, web framework for building APIs with Python 3.7+.
-
SQLAlchemy Database: Leverages SQLAlchemy, a powerful SQL toolkit and Object-Relational Mapping (ORM) library.
-
Strawberry GraphQL: Implements Strawberry, a GraphQL library for Python with a code-first approach.
-
SQLite3 Database: Utilizes SQLite3 as the backend database for ease of setup and portability.
Follow these steps to download, install requirements, and start the FastAPI server:
- Ensure you have Python 3.7 or higher installed.
-
Clone the repository:
git clone https://github.com/your-username/your-fastapi-project.git -
Change into the project directory:
cd graphql-fastapi -
Create and activate a virtual environment:
python -m venv venvsource venv/bin/activatevenv\Scripts\activate -
