About this project

What does Matthiesen Lib API add?

Matthiesen Lib API

⚠️ This mod has been deprecated and is no longer going to receive updates. This library has been replaced by Matthiesen Core which provides a more robust and feature-rich foundation for mod developers to build upon.

Matthiesen Lib API is the server-side API for Matthiesen Lib, a lightweight Architectury-style library that enables
mod developers to write shared code that works seamlessly across both Fabric and NeoForge mod loaders for Minecraft 1.21.1.
Instead of maintaining separate implementations for each platform, you can write your mod logic once in common code and let
Matthiesen Lib handle the platform-specific details.

Note: For regular users, This library does nothing on its own - it's a developer tool. If a mod requires Matthiesen Lib API,
simply drop it in your mods folder alongside the mod that needs it.
