Conditional Module Loading
Load large data or modules only when a feature is activated.
Example (lazy-load animation frames):
function AnimationPlayer({
enabled,
setEnabled,
}: {
enabled: boolean;
setEnabled: React.Dispatch<React.SetStateAction<boolean>>;
}) {
const [frames, setFrames] = useState<Frame[] | null>(null);
useEffect(() => {
if (enabled && !frames && typeof window !== "undefined") {
import("./animation-frames.js")
.then((mod) => setFrames(mod.frames))
.catch(() => setEnabled(false));
}
}, [enabled, frames, setEnabled]);
if (!frames) return <Skeleton />;
return <Canvas frames={frames} />;
}
The typeof window !== 'undefined' check prevents bundling this module for SSR, optimizing server bundle size and build speed.
