Summer '26 introduces a formal state management pattern for LWC, enabling multiple components on a page to share data through a central store rather than passing it via events.
Where
Available for Lightning Web Components in Lightning Experience. Uses the new state manager module from the LWC framework.
How
Define a shared state store in a service component. Other components import the store and subscribe to relevant slices of state. When one component updates the state, all subscribed components automatically reflect the change without additional server calls or custom event wiring.
Why
Complex component trees in Salesforce pages previously required long chains of custom events to propagate data changes between sibling or distant components. A central store eliminates this complexity and makes large component compositions more maintainable.
