Lwc Cross Tab State Sync

Category: General  ·  Sub-category: general-misc  ·  Last updated:
Use when an LWC needs to react to events that happen in another browser tab — record updates, login state, draft autosave, console-tab navigation. Triggers: 'sync data across tabs', 'BroadcastChannel LWC', 'storage event LWC', 'one tab updates the other', 'console workspace tab close detection'. NOT for state sync within the same Lightning page (use Lightning Message Service) or for server-pushed updates (use CometD or refreshApex).

From the source SKILL.md

Activate when a Lightning Web Component must react to something that happens in another browser tab — for example, the user updates a record in tab A and tab B has a stale view. The skill produces a same-origin sync implementation using BroadcastChannel (preferred) or the storage event (fallback), wired into LWC lifecycle hooks with proper cleanup.

What this skill does
