Description

Matthiesen Lib API

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.

Docs

Documentation for the library can be found at mods.matthiesen.dev
