@loontail/minecraft-kitMinecraft launcher kit

Stateless TypeScript library and interactive CLI for installing, verifying, repairing, and launching Minecraft — vanilla, Fabric, and modern Forge.

Library + CLI

TypeScript facade plus interactive mckit CLI, backed by the same code.

Symmetric list/resolve for Minecraft, Fabric, Forge, and Mojang Java runtimes.

Downloads the installer, runs processors with the installed Mojang JDK, verifies every output hash.

Discriminated-union onEvent covers every download, integrity check, processor, and launch transition.

Per-aspect verifiers (minecraft / fabric / forge / runtime) with a repair flow that re-downloads only what's broken.

Writes only the files Minecraft expects — no profile registry, no session files.
