I am curious because it's not simple to make a good network code for realtime games and I'd like to know how it has been approached in CS2D which plays pretty well.
I would like to know how and when is data synchronised, movement, shooting etc.

Yazir: Tickrate and events. And for bullets, imao clients should send player rotation while shot and then server should calculate the hit. Yazir: Client side projectiles thrown by yourself are just a visual thing you see, the server notifies the actual projectile (that does damage and stuff) to the rest of the clients.So there's a delay between the moment you threw the projectile and the moment the server figured out that you threw a projectile, which is added to the time where the projectile actually explodes.
Edit: The time a message takes to arrive from the server to the client or viceversa can't be worked out, however, you can work out client-side interpolation when you're trying to deal with object movement. (In order to predict where the object could possibly be moving to)
You could use interpolation techniques like; lagrange, spline.
My goal is to make the most responsive and least resource using netcode possible.
Thank you for the information.
Gaios has writtenclients should send player rotation while shot and then server should calculate the hit.
Yes please do this if you want to give people the easiest method to make an aimbot.
!?!
Yates: I didn't talk about the security 
Yazir: What game engine are you using?@
Yates: Please don't do sarcasm, you are indeed correct in what you're saying but it is not necessary to bring the thread down with a negative discussion. Starkkz: sad 
OnlineI'm sending the launch position and direction with projectiles in CS2D but only grenades and special weapons like rocket launchers have actual projectiles which are flying around. Of course the server has to validate if the player is close to the launch position to prevent cheating.
Shots in CS2D are not using projectiles. It's a simple message which only says "player x shot". No additional data. All other data like the current weapon and latest movement/rotation is sent with other packages. This is to minimize traffic as there are some high frequency fire arms in CS2D which shoot like every second frame.
Lag compensation in CS2D works by saving a list of old player positions. This allows you to go back in time to simulate the approximate game state at the time when the client shot locally.
I also implemented a tiny protocol on top of UDP to make CS2D work with a single UDP socket connection and minimal traffic. If you're using UDP directly you have to take care of things like reliable messages and message order as UDP is a simple "fire and forget"-protocol which doesn't guarantee that messages arrive in the right order or at all.
You should probably search for some articles and best practices as I can't tell you everything here
Starkkz: I am using Phaser framework with Socket.io@
DC: Thank you for the descriptive answer. I am searching for all the possible resources I can get to create the optimal (in terms of reliability and precision with least cpu and network usage). The information is not really anything new to me but it made me sure that I'm heading the right way 
Also, the fact that I'm doing this on webSockets puts it a bit apart from CS2D since it requires a bit different approach (TCP only).
Nonetheless, thank you for your time and I understand the reason behind not being able to tell everything
