CoryLib
Unified data storage and synchronization library for Minecraft mods. ⚙️
Quick answer
Which CoryLib release should I use?
CoryLib fabric-1.21.1-1.0.3 targets 1.21.1 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. All 2 required mods have matching files.
Where it goes
Is CoryLib required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does CoryLib fabric-1.21.1-1.0.3 need?
fabric-1.21.1-1.0.3. Change the file and its required mods may change too.
Install Architectury API, Fabric API first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does CoryLib add?
CoryLib⚡
A Minecraft Library for unified data storage and synchronization library for Minecraft mods.
Designed for mods that need a clean way to store, retrieve, version, and synchronize data across server, dimension, player, and client contexts.

So, why CoryLib? 🤷♂️
Minecraft mods often reimplement the same data systems over and over:
- Dimension-specific state
- Client preferences
- Server-to-client sync
- Runtime-only transient data
So CoryLib provides one fluent API for all of those cases.
public static final CoryContext DATA = CoryData.init("my_mod");
public static final DataEntry<ServerPlayer, Integer> KILLS =
DATA.player("kills", Codec.INT)
.defaultValue(0)
.storage(Storage.DISK)
.version(1)
.sync(SyncTrigger.IMMEDIATE)
.build();
You can check the repository for details and guides.

You can support by simply downloading the mod or donating me! Thanks if you do! 💕
