University mandatory project for the Enterprise half of the Advanced Programming Paradigms exam.

The project consists of a simple RESTful API written with .NET 8.0, Entity Framework, ASP.NET Core and Swashbuckle.

Disclaimer
This application is NOT to be used in an actual real-world scenario.
Despite implementing some basic security measures, like password hashing and use of JWT tokens, it is far from perfect and likely still has many unfound bugs and security vulnerabilities.
This application does not use https, does not revoke authentication tokens when a user changes their password or gets deleted (essentially because there isn't a refresh token), does not use an additional database secret on top of the per-user salt for hashing, and does not have any kind of rate limiting or IP banning features, nor does it apply email verification for new users registration.
It moreover does not use secrets or ignored files to hide the database password, because this is, once again, only an educational application, developer for a university exam.

The application models a very trivial use case for a library, while also providing a Swagger web interface to interact with the API.
The modeled library itself is very much simplified, it only having one many-to-many relationship between books and categories they belong to. The separation of authors and publishers from books was not required, and is left as a potential improvement to the project, as well as https support and some other minor details such as improved filtering and sorting.

Since the project was developed on ArchLinux, deploying it is made simpler by containerization of the whole infrastructure.
To run the application, simply use docker-compose -f docker-compose.yml up -d from inside the DotNetLibrary inner directory (where the .yml file is located).
The configured services will spin up the MySQL database and populate it using init.sql (exposing port 50666 for database connections), then build the DotNetLibrary.API Dockerfile and run it (exposing port 50667 for the Swagger interface).

Some scripts, both bash and powershell, are provided to:

• start docker services;
• start docker services while re-populating the database (deleting the previously created volume) and re-building the API project;
• stop docker services.

To test the application, visit http://localhost:50667/swagger using any browser.
