Reforged Fabric API
by TKD_Kedis
With Reforged Fabric API installed, a Forge mod can add biomes, entities and other content through one library layer, and that layer is what this card describes.
What it does
Reforged Fabric API is a Forge library that provides a core API for mods. Its biome API can modify vanilla biomes and add new biomes to the End and the Nether. Other features cover registering entities and similar game content without using Forge registries directly.
The library works with many other mods, though it does not work with the type registry. Client and server both need it: the server and every player must run the same build. Files exist for Forge 1.20.1 only, 1.20 – 1.20.1, with 0.87.0 as the latest file, released under the Apache License 2.0 and open source. Source code and an issue tracker are public.
