About this Mod

Fabric API

Essential hooks for modding with Fabric.

Fabric API is the library for essential hooks and interoperability mechanisms for Fabric mods. Examples include:

  • Exposing functionality that is useful but difficult to access for many mods such as particles, biomes and dimensions
  • Adding events, hooks and APIs to improve interoperability between mods.
  • Essential features such as registry synchronization and adding information to crash reports.
  • An advanced rendering API designed for compatibility with optimization mods and graphics overhaul mods.

Also check out Fabric Loader, the (mostly) version-independent mod loader that powers Fabric. Fabric API is a mod like any other Fabric mod which requires Fabric Loader to be installed.

For support and discussion for both developers and users, visit the Fabric Discord server.

Using Fabric API to play with mods

Make sure you have installed fabric loader first. More information about installing Fabric Loader can be found here.

The downloaded jar file should be placed in your mods folder.
