SSR and Next.js

SSR-safe factory

• Use createControllerForNext(() => ({ camera, domElement, ... })) in client components or after mount.
• On server, it returns a no-op stub; on client, it constructs the real controller.

Guards

• All DOM/window access is guarded; controller constructors avoid accessing DOM on server.

Resize

• Use setViewport({ width, height, devicePixelRatio }) wired via ResizeObserver on your canvas/container.
