Nirvana Library

by Clefal

Nirvana Library supplies shared code that other Clefal mods depend on, and it must be installed on the server and on every player's client.

What it does

Nirvana Library is a library mod for Clefal's mods. Several of them need it to start, so the server and every player run it. It bundles a standalone copy of the NeoForge event bus and Vavr, plus utility classes meant for developers writing code that works across loaders. Installed alone, it adds no blocks, items or commands. It requires Common Network and Fzzy Config, and it is published for Fabric, Forge and NeoForge across 13 release versions, 1.20.1 – 26.1.2, under the MIT License.

Key features

  1. Bundled event bus

    A standalone copy of the NeoForge event bus lets mods register and fire events without a loader-specific dependency.

  2. Bundled Vavr

    The Vavr functional library ships inside the mod, so functional types are available to other Clefal mods.

  3. Cross-platform utilities

    Utility classes help developers write one codebase that runs on Fabric, Forge and NeoForge.

Questions

Does Nirvana Library need Common Network and Fzzy Config?

Yes. Both are required dependencies and must be installed next to Nirvana Library on every loader.

Does Nirvana Library add anything to the game on its own?

No. Installed alone it does nothing; it only supports Clefal's mods that depend on it.
