LibJF
A library for my mods
Quick answer
Which LibJF release should I use?
LibJF 26.1.3 targets 26.1.2 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. No extra mods listed for this file.
Where it goes
Is LibJF required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does LibJF 26.1.3 need?
26.1.3. Change the file and its required mods may change too.
This file does not list any required mods. Do not add a library just because a different file uses it.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it
Add LibJF without breaking your instance.

About this project
What does LibJF add?
LibJF is a library for my smaller mods which contains several common components.
Namely it provides:
- a complete config system with UIs, commands, compile-time codegen, presets, verifiers, etc
- a framework for manipulating loaded data and resources
- two new tags (which you can also use in data packs):
libjf:overpowered: if an entity only wears armor items with this tag, it will become invulnerablelibjf:shulker_boxes_illegal: items with this tag cannot be placed inside shulker boxes.
Intended to be used for backpacks or similar items
- utility code for serialization, script loading, co-processes, IO, etc.
- network utilities including a HTTP client and server
- a configurable and extensible translation system supporting various providers
- utilities for early initialization and ASM patching
If a mod is made by me, it is generally safe to assume it requires LibJF (or ships with parts of it)
If you want to use LibJF yourself, you can find documentation here
