Persistent Storage

by Sygikal

Persistent Storage keeps chosen variables saved between worlds, so values carry over when a player starts a new save.

FabricClient-side onlyAll rights reserved1.18 – 1.21.8

What it does

The Fabric mod stores variables outside any single world, so data set in one save can be read again in another. It is a small library-style utility aimed at other mods and datapacks that need values to survive a world change. Persistent Storage runs on the client only, so a server does not need it. Files exist for 1.18 – 1.21.8, the latest being 1.0.2 for 1.21.8, released under All rights reserved and not open source.

Key features

  1. Variables kept between worlds

    Stored variables remain available after a player leaves one world and opens another.

  2. Simple, focused scope

    The mod does one job: saving and loading variables across worlds, with nothing else added.

  3. Client-side support only

    Support runs on the client for now. Server-side support is planned for a later release.

What the author says

Extremely simple mod allowing the storage of variables between worlds. Currently only client side, but could support server in the future. Adding Data: - PersistentStorage.put(String key, Object value) - PersistentStorage.putTag(String tag)
