About this project

What does Alexandria Lib add?

Alexandria is a lightweight library mod built to provide common utilities and abstractions for other mods. Named after the ancient Library of Alexandria, it serves as a central foundation of shared code, making development simpler and more efficient.



Features include:

📚 Shared Utilities – A collection of reusable helpers, data structures, and APIs.

⚡ Optimized Base – Reduces duplicate code across mods, ensuring better maintainability.

🧩 Modding Foundation – Designed as a dependency for mods, not for standalone gameplay.



If you see Alexandria in your mod list, it means another mod you’re using depends on it. By itself, Alexandria doesn’t add new content—rather, it makes other mods more powerful and easier to maintain.
