Ash API

by Trikzon

Ash API is a library that gives multi-loader developers one interface over Fabric and NeoForge, and it is the base layer for several Trikzon mods.

FabricForgeNeoForgeQuiltClient and serverGNU Lesser General Public License v3.0 onlyOpen source1.19.3 – 1.21.6

What it does

Developers who build a mod for both Fabric and NeoForge from one codebase can use Ash API to call shared code instead of writing separate loader-specific calls. The library sits between the two loaders and is meant to be paired with a multi-loader development template such as Jared's MultiLoader-Template.

Four mods in the catalog require it: Transparent, Armor Visibility, Shuffle and Flourish. Ash API depends on Fabric API, which must be installed alongside it on Fabric. The library runs on client and server, so both the server and every player need it when a required mod is present. Builds cover 1.19.3 – 1.21.6 across Fabric, Forge, NeoForge and Quilt, and the code is under the GNU Lesser General Public License v3.0 only.

Key features

  1. Key mapping registry

    KeyMappingRegistry offers a single way to register keybindings for both loaders.

  2. Block use events

    UseBlockEvent lets mods react when a player uses a block, through one shared event.

  3. Mod and resource loading

    ModLoader and ResourceLoader provide shared entry points for loading mod content and resources.

  4. Client tick hooks

    ClientTickEvents exposes tick hooks that mods can subscribe to during each client update.

Use cases

Multi-loader mod development

A developer maintaining one mod for Fabric and NeoForge can write shared logic once against Ash API.

Who it’s for: Mod developers who ship the same mod on Fabric and NeoForge and use a multi-loader development environment. Players who only need the four dependent mods do not interact with the API directly.

How it compares

Questions

Does Ash API need Fabric API?

Yes. Fabric API is a required dependency, so it must be installed alongside Ash API on Fabric.

Does the server need Ash API?

Yes. A server running it needs every connecting player to have it too.

Which mods require Ash API?

Transparent, Armor Visibility, Shuffle and Flourish require it, and each of them needs Ash API on the same side as the mod.

In the catalog

Ash API is one of 3,514 Library mods on ModsFinder, and one of 2,348 Library mods for Fabric. 13,625 mods support Minecraft 1.21.6.
