NetworkJS
by snowylol_
NetworkJS gives KubeJS scripts on a NeoForge server the ability to make HTTP requests to outside services, with global functions available from scripts.
What it does
Once the jar is placed in the mods folder and KubeJS is installed, scripts can reach the internet and exchange data with web services such as Discord. The mod exposes a set of classes and functions that are available globally inside KubeJS scripts, so a script can call them without extra setup. Server owners restart the server after adding the jar, and the mod is built for Minecraft 1.21.1.
The mod is aimed at server owners who write server scripts and want them to talk to external systems, for example to post server events to a chat channel or to read data from a web endpoint. It also adds server utilities, including the ability to send colored messages to players and to show them server information. Because the mod runs only on the server, players join without installing anything.
NetworkJS is published for NeoForge only, across eight release versions, with 1.1.0 for 1.21.8 as the latest file, first published on 2025-08-17 and last updated on 2025-08-23. The source code and issue tracker are public, and the mod is open source under the MIT License.
