"Architecture" (*ironic*)

I am not relly familiar with networking stack, so I decided to use one of the popular projects from github as the base for network-level communications. It provides async tcp server and client interface that I utilise. The library seems good enough to separate me from plain sockets (I don't want to die), and basic enough to be used in this demo task.

The application and server/client logic is divided by a clear hook-based interface. I would love to have something a bit more interesting, but the time was really short.

TODO

The project isn't really even an MVP, so there is a lot to fix:

• GoogleTests, I used my usual CMakeLists config with test lib dependency, but had no time even for unit tests
• Better UI, I have a pretty good idea, how to implement a nice console-based interface with readline, but again, time
• Better async, especially for IO
• Better MessageStructure, clients need MessageRecieved notification too
• Encryption, I had an idea in mind to implement obscure pub-key based encryption, similar to Shadowsocks, it would be hard to distinguish it on ISP-level because there aren't any headers, but...
