FTB Library (Fabric)


If you are looking for Forge version, it's here! https://curseforge.com/minecraft/mc-mods/ftb-library-forge

FTB Library serves as a foundational component for FTB Mods. It's designed to simplify and enhance the modding experience for our developers, streamlining the development process for mods within the Feed the Beast ecosystem. While primarily intended for use by FTB Mods such as FTB Chunks and FTB Quests, it is not explicitly prohibited for integration into non-FTB mods. However, please note that using it in such contexts may pose challenges, and the responsibility for resolving any resulting issues falls upon the mod developer.
