DevKit API

Lightweight modular library for Fabric 1.21.x mod developers

Why DevKit API

Writing the same boilerplate for every Fabric mod is exhausting. DevKit API collapses the repetitive parts — registry, networking, data components, config — into clean annotations and fluent builders, so you ship features instead of setup code.

What you get

• KRegister<T> — type-safe registry container, two lines per entry
• @AutoPacket — annotation-driven Payload S2C/C2S registration, no manual ByteBuf
• Components.builder(...) — fluent DataComponentType factory with persistent + networked codecs
• @SyncedConfig — server-authoritative JSON config with auto S2C sync
• ModelGen, TagHelper, LootHelper — datagen shortcuts
• DevkitNetworking — sendToPlayer, sendToTracking, sendToAll helpers
• NetworkCompat — runtime shim for 1.21.1 ↔ 1.21.8 API differences
