What it does

For mod authors, BlueLib offers helper systems that cut down the code needed to build a mod, and it handles both data packs and resource packs. Its stated goal is to make modding more accessible. Fabric API is required on Fabric, and Just Enough Items (JEI) is optional. Two catalog mods, Bluedude Dragons and BlueLib Common, require it. Client and server both need the library, so the server and every player must run it. Files cover 1.21 – 1.21.5, with the latest build, 2.4.3, targeting 1.21.3 and dated 2026-01-04.

Key features

  1. Shared modding systems

    Code development is simplified through reusable systems that other mods can build on.

  2. Data and resource pack support

    The library works with both data packs and resource packs, so content can be shipped that way.

  3. Source code and wiki

    The source code, an issue tracker and a wiki are public for anyone studying or contributing to the library.

Questions

Does BlueLib need Fabric API?

Yes. Fabric API is required on Fabric. Both must be installed next to BlueLib on that loader.
