Fabric Plugin Messaging

by Stampede

Fabric Plugin Messaging is a Fabric library for sending and receiving plugin messages on a proxied network, with one packet listener API so mods do not register their own packets.

FabricServer-side onlyMozilla Public License 2.0Open source1.21.1 – 1.21.4

What it does

The library gives server-side mods a standard way to register a plugin message packet and react to plugin message events, which removes the need for each mod to build its own packet handling. Developers use it in their projects, and it runs only on the server side, so players join without installing it. Fabric Plugin Messaging is published for 1.21.1 – 1.21.4 under the Mozilla Public License 2.0, and it requires Fabric API.

Key features

  1. Plugin message packet

    A packet class lets a server-side mod register and send plugin messages across the proxied network.

  2. Plugin message event

    Mods subscribe to a shared event to receive plugin messages without writing their own network listeners.

  3. Shared packet listener

    A single packet listener handles registration, so separate mods do not clash when they register the same packets.

What the author says

A Fabric plugin messaging library! This server-sided mod will register a Plugin Message Packet (PluginMessagePacket.class) and a Plugin Message Event (PluginMessageEvent#EVENT) for developers to use in their projects. Without this mod, developers would need to register their own packets, which would cause conflicts…
