Jauml
Jauml is a lightweight configuration library for Minecraft mods, designed to simplify JSON-based config management
About this Mod
This beta release of Jauml lays a solid foundation for managing mod configurations in Minecraft. Whether you're adding new settings or validating existing ones, this library streamlines the process with clean, maintainable code. It’s an essential tool for mod developers looking to enhance their projects with flexible config options.
Usage for Developers
Jauml is a library dependency. Players usually install it because another mod requires it.
| Step | Action |
|---|---|
| Add dependency | Depend on Jauml from your Fabric / Forge / NeoForge build |
| Create config | Define your settings with Jauml’s JSON config helpers |
| Load on startup | Read and validate config when your mod initializes |
| Save changes | Write updates back through the same config layer |
| Ship with your mod | List Jauml as a required dependency on CurseForge / Modrinth |
Configuration
Jauml itself is a library. Your mod owns the config files.
Typical pattern:
- Your mod declares settings through Jauml
- JSON config files are generated / updated under the usual Minecraft config folder
- Invalid or missing values can be validated and restored to safe defaults
Example shape (illustrative):
{
"enabled": true,
"debug": false,
"values": {
"exampleOption": 1
}
}
Exact keys depend on the mod using Jauml.
Compatibility
- Singleplayer
- Multiplayer / dedicated servers (as required by dependent mods)
- Fabric
- Forge
- NeoForge
- Large modpacks
- Client + server (library; follow the dependent mod’s side requirements)

Jauml server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.2). You can switch loaders with one click in the panel.
Is Jauml compatible with fabric and forge and neoforge?
Jauml officially supports fabric, forge, neoforge for Minecraft 26.2, 26.1.2, 26.1.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Jauml – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Jauml consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
