What is Composer?

Composer is a general-purpose Fabric library mod developed under Project Codex.
It provides shared systems, utilities, and architectural building blocks used across multiple mods, with a focus on clean APIs, long-term stability, and multi-version support.

Composer does not add gameplay content on its own (except for a plushie). It exists to support other mods at runtime and during development.

For more details, take a look at the wiki!

If you want to use Composer as a library in your mod, add the Composer Maven repository and Cardinal Components
repository to your build file, then add Composer as a dependency.

Replace (latest_version) with the latest Composer version compatible with your Minecraft version.
