Pufferfish API

by awesomekalin

Pufferfish API is a library for authors who want one codebase to target several Minecraft versions and loaders.

FabricForgeNeoForgeClient and serverMIT LicenseOpen source1.20.6 – 26.3

What it does

Pufferfish API gives mod developers a shared base for building mods that cover multiple game versions and multiple loaders from a single source. The mod adds no gameplay content of its own, so players only install it because another mod depends on it. Fabric API is required, and The Pro's Game is one of the mods that requires Pufferfish API. Files cover 1.20.6 – 26.3 for Fabric, Forge and NeoForge, and the code is open source under the MIT License.

Key features

  1. Single-source builds

    One project can produce builds for several game versions without maintaining a separate copy of the code for each.

  2. Shared mod base

    Authors write common code once and reuse it across their projects, instead of rewriting the same plumbing for each release.

  3. Developer-only library

    The library is meant for mod authors and contributes no items, blocks or mechanics to a game.

What the author says

Pufferfish API is a library mod that makes it easier to develop multi-version and multi-loader mods with a single codebase. This is primarily built for my mods (excluding BTA), so stuff could break at any time, and you probably shouldn't build your own mods on top of this. This also doesn't add any content, so you…
