SolLib
by Lyof
SolLib is a library mod of data, multiloader and rendering helpers that other mods can call from common code without hard dependencies.
What it does
The library exposes a set of utilities for mod developers. Most of them concern datapack handling, multiloader code and rendering. Other mods can load it on demand, so an add-on does not have to declare it as a hard requirement.
One datapack helper lets a mod edit datapack files at runtime. A developer can use it to change recipes according to config values, edit or disable compatibility recipes when their target mods are missing, and generate models for dynamically defined items. Common code calls the same API on every loader, so separate mixins are not needed for each one.
SolLib is published for Fabric, Forge and NeoForge, with files for 1.20.1 – 1.21.11. It runs on client and server, so both sides need it. The project is distributed under a custom license. Mods that require it include Sortilege, Combat Bash and Wrathy Armament.
Key features
Runtime datapack editing
Mods can change datapack files while the game runs, for example to adjust recipes after config values are read.

Use cases
Add-on compatibility
An add-on mod can ship recipes that depend on another mod and switch them off when that mod is not installed.
Config-driven recipes
A pack author can alter recipes according to a setting, without shipping a separate datapack for each variant.
Who it’s for: Mod developers who build content across Fabric, Forge and NeoForge and want shared data and rendering helpers. Players do not interact with the library directly.
