LifeCompat
by 2Bad4Mods
LifeCompat is a Fabric library that gives other mods shared APIs for buckets, events, and energy, so compatibility code does not have to be written from scratch in each mod.
What it does
The Bucket API lets a mod register custom bucket types, such as a wooden bucket, and add new fluids that those buckets can hold, alongside the vanilla ones. The Event API exposes common game events, including BlockBreakEvent, ItemUseEvent and PlayerDeathEvent, and lets a mod create its own events for other mods to listen to. The Energy API adds a way for blocks to provide, store or consume energy, which the author describes as a different approach to energy compatibility between mods.
Fabric API is required and must be installed alongside LifeCompat. Skylife requires LifeCompat, so it is one of the mods that depends on this library. LifeCompat runs on client and server, so the server and every player need it. Files are published for Fabric only, for game version 1.21, and the code is released under the MIT License as open source.
Key features
Custom bucket types
Mods can add buckets made from other materials and register fluids that those buckets hold.
Listenable game events
Common events such as block breaks, item use and player deaths can be subscribed to by other mods.
Custom events
A mod can define its own events, so the events it fires are available to other mods built on the library.
Energy API for blocks
Blocks can be given the ability to provide, contain or use energy through the shared energy interface.

How it compares
Kielson's API is also an MIT-licensed, open source Fabric library, with files for 1.21 – 26.2 and the same client and server environment as LifeCompat. GoreLib is a CC0 1.0 Universal open source Fabric library for 1.19 – 1.19.2 that also runs on client and server. BlunthornAPI is an MIT-licensed open source Fabric library for 1.20.1 – 1.20.6 that has no environment listed. LifeCompat covers only game version 1.21, so it does not reach the earlier range of GoreLib or BlunthornAPI.
