EpheroLib Mod (1.21.11, 1.20.1) – Library for Thethonk's Mods

If a mod by thethonk asks for a shared library, EpheroLib Mod is the part that makes that setup possible. It bundles common systems for config handling, networking, server-side translations, and world data storage, and it does so without adding any direct gameplay content to Minecraft.

Key Features

  • Provides a shared config system through Configurate for Fabric and Forge setups.
  • Abstracts networking to hide the packet differences between Fabric and Forge.
  • Includes server-side translations built with GSON, reducing the need to distribute language files to the client for supported server-side mods.
  • Offers a GSON-based storage abstraction for per-world data.
