How to inspect all active event listeners registered by server resources in FiveM:

In CitizenFX Lua:

LUA
-- Hook AddEventHandler to log all incoming server events
local originalAddEventHandler = AddEventHandler
AddEventHandler = function(eventName, handlerRoutine)
    print('[EVENT REGISTERED]:', eventName)
    return originalAddEventHandler(eventName, function(...)
        print('[EVENT TRIGGERED]:', eventName, 'Args:', json.encode({...}))
        return handlerRoutine(...)
    end)
end

Dumps every inventory sync, bank deposit, and admin alert event directly to your local console window.

Hooking AddEventHandler reveals all server-to-client network protocol structures in seconds. Excellent tool.

Similar to hooking RemoteEvents in Roblox. Lua event models are so transparent.
