Chat-App | Chat application with user authentication

Chat-App is a C# library. Chat-App has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Over the span of a couple months I built this app to increase my knowledge of the C# framework .NET Core, client/server-side relationships and management/utilization of a relational SQL database. I also have always been fasinated with how chat applicatiions work since my earliest internet experience with AOL chat rooms. I used React.js to handle the client-side and React-Router library for handling routhing between React components. When it came to styling this app, I chose a mix of css and Bootstrap because Bootstrap's library creates a very conveinant solution to screen responsiveness and layout which can come in handy when you are under a time crunch. I also added several css edits to the Bootstrap for custimization such as container and div sizes and their positioning along with media quiries for screen break points. The back-end of my application was built with C# .NET Core which has been a wonderful framework for seprerating client-side and server-side buisiness logic. HTTP requests are made from the client-side and sent to the internal API endpoints in a controller. From there, the controller connects to services which then make the appropriate SQL calls to the PostgreSQL requesting or posting data back from and to the front-end. For the SQL calls I had some help from the open-source data provider Npgsql, which allows access to the PostgreSQL server for programs written in C#. For unit testing, I used Nunit framework to perform tests on important functionalities such as creating a new user, and sending a new message.
