For mod developers juggling configuration files across multiple loaders, Resource Config API Mod offers a straightforward solution that cuts through the complexity. Created by xStopho, this lightweight library handles the creation, saving, and autocorrection of mod config files — supporting Forge, Fabric, NeoForge, and Quilt from a single codebase. With over 140,000 downloads on Modrinth and active development since early 2024, it has quietly become a reliable backbone for multi-loader Minecraft projects.
Key Features
- Broad data type support — Store primitives like Integer, Double, String, and Boolean alongside reference types such as List, ArrayList, and LinkedList, covering most configuration needs out of the box.
- Commented values and categories — Add inline comments to individual config values and entire categories, making config files readable for both developers and end users who want to tweak settings manually.
- Range-defined values — Constrain numeric values within a defined range so invalid entries are caught automatically before they cause issues in-game.
- Autocorrection of invalid configs — If a config file becomes corrupt or contains out-of-range values, the API automatically corrects them to valid defaults rather than crashing the game.
- Custom config paths — Specify exactly where config files are stored, giving developers flexibility over file organization within their mod structure.
- Multi-loader design — Built from the ground up to work across Forge, Fabric, NeoForge, and Quilt, so developers can maintain a single config system for all loader versions of their mod.

How to Install
- Install your preferred mod loader — Forge, Fabric, NeoForge, or Quilt — matching your Minecraft version.
- If using Fabric, make sure Fabric API is also installed. For Quilt, install Quilt Loader.
- Download the correct Resource Config API file for your Minecraft version and loader from the link below.
- Place the downloaded
.jarfile into your.minecraft/modsfolder. - Launch Minecraft. The API loads silently in the background — no in-game content is added since this is a library mod.

FAQ
Do I need Resource Config API if I'm just playing Minecraft?
Only if another mod you have installed lists it as a dependency. On its own, Resource Config API adds no gameplay content — it is a behind-the-scenes library that other mods use to manage their configuration files.
Does Resource Config API work with both Forge and Fabric at the same time?
It supports Forge, Fabric, NeoForge, and Quilt, but you need to download the correct version for your specific loader. The multi-loader design benefits mod developers who want to maintain one config system across platforms.
What happens if a config file gets corrupted?
The API includes built-in autocorrection that detects invalid or out-of-range values and resets them to valid defaults automatically, so a broken config file should not prevent your game from launching.
