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.

A rewrite 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.
