## What it is
Fabric API is the essential hooks and interoperability library for Minecraft mods built on the Fabric mod loader. It exposes events, APIs for rendering, networking, registries, and other game functionality that mods depend on.

## Use cases
- develop a fabric mod for minecraft
- add event hooks to minecraft mod code
- install the base library needed by fabric mods
- use a rendering api compatible with optimization mods
- synchronize mod registries across client and server
- build a minecraft mod with gradle

## When to choose
- you are developing a Fabric mod and need core hooks and APIs
- you are a player whose Fabric mods list Fabric API as a dependency
- you need interoperability between multiple Fabric mods

## When to avoid
- you use Forge or NeoForge instead of Fabric
- you want a standalone mod rather than a dependency library
- you need a mod loader itself - use Fabric Loader instead

## Facets
- artifact type: library
- maturity: active
- function: plugin-system, middleware, sdk, graphics, networking
