StorageManager API
Other mods can keep structured data between sessions in an SQLite database through the StorageManager API, a server-side library for Fabric.
What it does
Mod developers use the library to manage storage systems for their own features. Data is written to SQLite databases, and writes are cached asynchronously so that frequent saves do not block the server thread. The API is designed for clean, stable use from server code, and it logs operations and warnings while it loads.
The library itself adds no gameplay. Server owners who run mods that depend on it need StorageManager API installed beside them, and Fabric API must be present as well. The current build targets 1.21.1 only, and the author plans to consider more versions later. The code is released under the MIT License and is open source.
Key features
SQLite-based persistent storage
Mods store persistent data in SQLite through the library, so their records survive restarts without each developer writing a database layer.
Asynchronous write caching
Writes are queued and cached asynchronously, which reduces the time spent waiting on storage operations during play.
Stable server-side API
The interface is meant for server-side code, giving dependent mods a consistent set of calls for reading and writing structured data.
Operation logging
The library logs its operations and warnings, which helps developers and server owners see how stored data is being handled.

Use cases
Gameplay mods with saved state
A gameplay mod that must remember player progress, claimed areas or machine contents can keep that data in a shared database instead of its own files.
Who it’s for: Mod developers building server-side features that need reliable structured persistent data, and server owners who run those mods.
