Fabric Loader

The Fabric Loader is the foundation of the Fabric ecosystem. It loads mods and provides the runtime environment, which can be extended through the Fabric API.

What the Fabric loader does

Mod Initialization
It hooks into the game’s startup sequence to load and execute mod code properly.

Dependency Management
It checks your mods, verifies that required dependencies (like the Fabric API) are present, and prevents version conflicts.

Class Transformation
It uses a tool called Mixins) to safely modify existing game code without heavily altering the core game.
