HammerLib

HammerLib is a Minecraft utility library that helps mod developers register content with annotations, handle networking, and serialize NBT data. It also supports Java-based recipe and tag registration. Available for NeoForge and Forge, it covers Minecraft versions 1.12.2–1.21.4.

Rent your own Minecraft server and install HammerLib in one click from the panel to provide the library required by mods that depend on it.
