Help needed for a server-side mod

[Residays]

Hello, I have just downloaded the mod tools and have already made some files to start modding, the problem is I don't know how to interact with Don't Starve Together's API, so here's where ask my questions:

Where can I find a reference for the API of Don't Starve Together?

If that's not possible, how can I start a function with the following?:

Player connected to the server.

Player disconnected to the server.

Player has been in the server for some time.

Player has not been in the server for some time.

Disabling world resets and votekicking.

Enabling world resets and votekicking.

If possible, please contact me via Steam ( http://steamcommunity.com/id/Residays ) or Discord ( Residays#1278 ) because I am not very active in Klei forums, so if a large argument's gonna happen it'll be slow, thanks in advance.

I'm pretty sure I can mod, the problem is I don't know how to interact with the API because I don't know how to reverse engineer.
