Type Alias: LaunchAspect

type LaunchAspect = {
  compose: Promise<LaunchComposition>;
  preflight: Promise<LaunchPreflightResult>;
  run: LaunchSession;
};

Defined in: src/kit/launch-aspect.ts:26

Shape of kit.launch.

Methods

compose()

compose(target, options): Promise<LaunchComposition>;

Defined in: src/kit/launch-aspect.ts:27

Parameters

Parameter	Type
target	Target
options	LaunchOptions

Returns

Promise<LaunchComposition>

---

preflight()

preflight(target): Promise<LaunchPreflightResult>;

Defined in: src/kit/launch-aspect.ts:42

Cheap, network-free readiness gate: reports whether every launch-critical file (java executable, version JSON, client jar, classpath entries) is present on disk. The network-free subset of verify.targetReady.run, reporting the same shape.

Parameters

Parameter	Type
target	Target

Returns

Promise<LaunchPreflightResult>

---

run()

run(composition, options?): LaunchSession;

Defined in: src/kit/launch-aspect.ts:36

Spawn the game. The only run in the library that is not async: it returns the live LaunchSession synchronously so the caller holds pid and abort() immediately. awaiting it yields the session, not the exit — wait on session.exited for that.

Throws LAUNCH_JAVA_NOT_FOUND before spawning when composition.javaPath is an absolute path that is not a file.

Parameters

Parameter	Type
composition	LaunchComposition
options?	LaunchRunOptions

Returns

LaunchSession
