ServerLibraries
by Relism
ServerLibraries is a Fabric library for building server-side mods, with mapped events and sync or async task scheduling.
What it does
The library is aimed at developers who write server-side Fabric mods and want a workflow that feels closer to writing a Bukkit-based plugin. It exposes hundreds of mapped events behind a simplified handler layer, so mod code can react to server activity without working through raw Minecraft mappings. Scheduling of both synchronous and asynchronous tasks is built in. Server-side only, so players join without installing anything. Fabric API is required, and the files target 1.20.1 – 1.21.1 under the GNU General Public License v2.0 or later.
Key features
Simplified event handling
Hundreds of server events are mapped to a simpler interface, so handlers can be written with less boilerplate.
Sync and async scheduling
Tasks can be queued to run on the main server thread or in the background, depending on the workload.
Plugin-style development
The API is shaped to resemble Bukkit-based plugin development for developers who already know that style.
