Ticket 2 - FastAPI: FastAPI Server Setup for Nomic Game

[mustafakucuk0]

Description: The aim of this task is to initiate the setup of a FastAPI web server for our Nomic game, transitioning from the previously considered Flask framework. This setup will provide the foundation for the application's structure and initial functionality.

Key Tasks:

FastAPI Installation and Virtual Environment Setup:
    Create a new Python virtual environment using Poetry to manage dependencies, ensuring an isolated development environment.
    Install FastAPI along with Uvicorn, an ASGI server, to serve the FastAPI application.

FastAPI Application Structure:
    Establish a structured application directory by creating an app folder. Within this folder, set up the following files:
        __init__.py: Initializes the FastAPI application instance.
        main.py: Serves as the entry point for the FastAPI application, importing the app instance from __init__.py.
        routes.py: Manages all the route declarations.

Initializing FastAPI App:
    In the __init__.py file, import FastAPI and instantiate the application object.
    Set the application to run in development mode for ease of debugging.

Defining Routes:
    Home Route (/): In routes.py, define a route that returns a welcoming JSON response or HTML page, introducing players to the Nomic game.
    Placeholder Game Route (/game): Add a temporary route for /game that returns a message indicating that game functionalities are being developed. This will later serve as the entry point for game interactions.
    API Documentation Route: Implement Swagger to have automated documentation.

Running the FastAPI Server:
    Ensure the FastAPI application can be launched locally using Uvicorn and is accessible through a web browser.
    Update the README file with instructions on starting the server and navigating to the home and documentation routes.

Document the Setup Process, Application Structure, and Purpose Behind Each Route:
    Talk about how to spin up a local database.

Data Model Preparation:
    Ensure we define the model used in our database and how that data is structured.

Deliverables:

A Python virtual environment managed by Poetry with FastAPI and Uvicorn installed.
An organized app directory featuring __init__.py, main.py, and routes.py for application initialization, entry point, and routing respectively.
A fully operational FastAPI application capable of being served locally, with a welcoming home route and a placeholder for game interactions.
A database connection for the Nomic game.
A README file with clear setup and server start instructions, alongside instructions on local DB usage.

Considering the workflow and the concerns raised, I suggest incorporating a step focused on security and testing early in the development process. Specifically, after setting up the FastAPI and Uvicorn dependencies, introduce a step for integrating security practices and a testing framework. This could involve setting up Pytest for testing and using tools like SQLAlchemy ORM to mitigate SQL injection risks, as well as implementing input sanitization to protect against XSS. Additionally, configuring environment variables for sensitive information right from the start can enhance database connection security. This proactive approach ensures that security and testing are not afterthoughts but integral parts of the development workflow, aligning with the concerns about security vulnerabilities, database connection security, and the need for testing and continuous integration.
