deduplicate-global-event-listeners

To optimize global event listeners in React, you can deduplicate multiple instances into a single shared listener. This Skill uses `useSWRSubscription` to ensure only one listener is active, improving performance and reducing memory leaks when handling shared events like keyboard shortcuts.

Creating multiple keydown event listeners causes performance problems because each component instance registers its own listener, leading to redundant processing and potential memory leaks. Deduplicating these into a single listener that dispatches callbacks to relevant components resolves this inefficiency.

Yes, you need the `swr` package installed in your React environment to use this event listener deduplication approach. The Skill implements `useSWRSubscription` to manage shared listeners and efficiently dispatch callbacks to multiple components.

The best way to manage shared keyboard shortcuts in React is deduplicating global event listeners. By utilizing `useSWRSubscription`, a single listener can manage and dispatch callbacks to all relevant components, ensuring optimal performance and preventing memory leaks.

Yes, you can use this event listener optimization for non-keyboard events in React. The `useSWRSubscription` mechanism manages callbacks for any shared global events, ensuring only one listener instance is active regardless of the event type being dispatched.
