Packet Logger mod
This mod logs all packets (including all relevant data) that you send to the server, and saves it to a seperate JSON (written and saved on disconnect, inside the 'packet-logs' folder) file with timestamps!
Why not incoming packets?
Minecraft code is non human readable, so reading packet class names leads to a non human readable output, I've had to manually list packet names for each outgoing packet, I do plan to add support for all incoming packets in the future!
Dependencies
This mod requires Fabric api, and Cloth config + Mod menu for configuration.
