DataGear is a powerful hot-reloadable Fabric library mod for Minecraft 26.1+ that exposes components, flags, and other modifiers as data. It allows developers to modify them using simple JSON datapack files without writing a single line of code.

Mod, Datapack and Modpack developers: Read the wiki to see how to use DataGear.

Features

Data-Driven items: Modify any component or modifier such as armor points, toughness, attack damage, speed, durability via datapacks.
Live Reload: Use /reload to apply changes instantly.
Simple yet powerful JSON engine: Easy-to-understand data structure. Read the wiki to see examples.

Compatibility & API

DataGear is meant to be a simple and lightweight solution, and as so it's designed to work seamlessly with other mods.

Tagging: DataGear adds some tags to help you target items. See them here.
Dynamic Discovery: Dynamically searches for modded modifiers and components, supports most mods out of the box as long as they don't do anything weird.
Custom Slots: Includes a DataGearPlugin API for mods to register custom slots (like Curios, Trinkets, or Accessories).

If you encounter any issues or incompatibilities, please report them here.

Datagear V2 is under development. To see my ever-expanding but never-fulfilled TODO list, click here.

The mod is available for Neoforge and Fabric 26.1+ and MIGHT be backported to 1.21.1 for both loaders. No Forge or 1.20 ports are ever happening.
