NAIF API
by naif team
NAIFapi is a utility library for Minecraft 1.21 mod developers, offering reusable APIs and systems that a project can build on instead of writing its own infrastructure.
What it does
Developers who build mods on Fabric, NeoForge or Quilt can use NAIFapi to cut down on repetitive code. Its collection of developer-focused tools covers common groundwork so that a project can focus on its own content and experiences. The library is lightweight, which keeps the foundation small for projects of any size, and it fits into existing codebases without adding unnecessary complexity.
NAIFapi is maintained by Naif Hani and supports the 1.21.x release series, with files for 1.21 – 1.21.11. Every player and the server need a copy of the mod. Dependent mods detect NAIFapi automatically. Players usually do not need to install it unless another mod requires it. The library is released under the MIT License and is not open source.
Key features

Practical APIs and systems are bundled together so developers can reuse them across several projects.
Less repetitive code
Common infrastructure is provided by the library, which reduces the amount of boilerplate a mod has to contain.
Cleaner project structure
Using shared components helps keep mod codebases organized as they grow in size and scope.
Lightweight integration
The library is small and can be added to a project without pulling in large amounts of extra functionality.
