Respond to Location Filter Changes

Custom components should respond to global filter changes if possible, to provide a cohesive Command Center user experience.

Components that must respond to global filter changes should subscribe to the Command Center standard Lightning Message Service channels. To reference a message channel, import it from the @salesforce/messageChannel scoped module. To use the Lightning Message Service APIs:

• Import the following functions from lightning/messageService: subscribe, unsubscribe, MessageContext, and APPLICATION_SCOPE.
• Import COMMAND_CENTER_MSG_CHANNEL from @salesforce/messageChannel/lightning__CommandCenterMessageChannel.

The following example, from the sample app at https://github.com/forcedotcom/WorkDotCom-Partners, demonstrates subscribing and unsubscribing to the Command Center message channel and listening for events fired.

While Lightning Message Service allows any component to publish a message on any channel, the Command Center global filter component does not subscribe to any LMS channels, so it won’t receive any messages published by other Command Center components.
