AlfinoLib

Library for networking and datapacks across Forge and NeoForge.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Mod loader NeoForge1 build
Mod loader Forge1 build

Minecraft version

Minecraft 1.21.1Newest

Minecraft 1.20.1Newest

⬇ Download for 1.21.1 · NeoForge ⬇ Download for 1.20.1 · Forge

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

AlfinoLib is a library I use in all of my mods - it is a combination of the old Alfino's Datapacks/Alfino's Networking.

The library contains abstractions for datapacks and networking (the big win is stream codec standardisation!) - making version maintenance between Forge 1.20.1, NeoForge 1.21.1, and NeoForge 26.1 (hopefully) a bit easier :)

There are more planned abstractions in the future too, with the aim of making maintaining multiple versions easier.
