WrapperLib
multi-platform library for easier data serialization
About this Mod
WrapperLib
A collection of multi-platform implementations of common tasks for developing Minecraft mods.
- Provides a uniform api across mod loaders and Minecraft versions.
- A priority is placed on never manually writing serialization code for nbt or byte buffers.
- Designed to be modular, so you can shadow only the parts you need and have no external dependencies.
- Each api concept is exposed as a Builder like class with no additional setup required.
- Extensive documentation (wiki & javadocs).
See wiki for more info.
- NetworkWrapper: send information between the client and the server.
- ConfigWrapper: allow players to configure mod features by editing json files.
- DataWrapper: save extra information with world data.
- RegistryWrapper: an api like Forge's deferred register that can be called from common code.
- Helpers: simple utilities for multi-platform mods.

WrapperLib 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 (1.19.3). You can switch loaders with one click in the panel.
Is WrapperLib compatible with fabric and forge and quilt?
WrapperLib officially supports fabric, forge, quilt for Minecraft 1.19.3, 1.19.2, 1.19.1. 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 WrapperLib – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if WrapperLib 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.
