Registry Helper Library
Registry Helper Library, a small Fabric utility API, lets mod developers register items, blocks and armor without writing registry boilerplate by hand.
What it does
Developers normally build a ResourceKey and an Identifier for each entry, then wire them through Registry.register calls. This library replaces that wiring with one RegistryHelper instance per registry and a few purpose-built methods, so a single object handles each registration. Plain items and blocks are covered out of the box, and BlockItems are generated automatically for blocks that need them. Full four-piece armor sets are handled as well, while a generic register method remains available for other vanilla registries such as sounds and entities.
The library also keeps track of everything it registers, so a mod can loop over its items and blocks later, for example to fill a creative tab. Its API is meant to stay backward-compatible and to cut down repetitive code. It requires Fabric API and runs on client and server, so both the server and every player need it. Files are published for Fabric only, with builds covering 1.20.1 – 26.2. The code is under All rights reserved, so it is not open source.
Key features
One helper per registry
Each registry gets one RegistryHelper instance, and simple methods replace manual key and identifier construction.
Automatic BlockItems
Blocks registered through the library receive their BlockItems automatically, so no separate item call is needed.
Armor set registration
Full four-piece armor sets can be registered in one call, while a generic method still covers other registries.
Registration tracking
Everything registered through the library is recorded, so a mod can loop over its contents later, for example for a creative tab.
