Tiny DataLib
Tiny DataLib is a lightweight library for server owners and datapack authors, with a macro-powered API for building mechanics and debugging NBT.
What it does
The library is meant to take on the heavier parts of datapack development. Its macro-based API lets a single function call run a set of operations, and it accepts variable inputs for function calls that adapt to different arguments. It also includes utility modules for a database system, tools for working with mannequins and armor stands, and attribute management.
Because the library is required on the server, the server must run it, while players may add it on the client for their own use. The mod is licensed under the MIT License and is open source. Files are published for Fabric, Forge, NeoForge and Quilt, and every build targets 1.21.11 only. Public source code, an issue tracker and a wiki are available.
Key features
Macro-powered API
Macros let developers write game mechanics with variable inputs and fewer repeated commands.
Entry-based logic
Calculations are organized into entries so that high-frequency work keeps tick-rate stable and reduces lag.
Raycasting and hitboxes
The library adds raycasts and improved entity hitbox detection for precise checks.
Item handling
Custom give commands stack items sensibly, handle overflow and support components.

Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Heavy datapack projects
Large datapacks can move repeated logic into the library to keep function files shorter.
Persistent entity data
Calculating complex distances and storing persistent entity data is covered by the distance and entity modules.
Who it’s for: Datapack authors who build mechanics on a server, and server owners who want the library available for those datapacks.
