# @fluentui/react-message-bar The MessageBar component communicates important information about the state of the entire application or surface. For example, the status of a page, panel, dialog or card. The information shouldn't require someone to take immediate action, but should persist until the user performs one of the required actions. ```tsx import { MessageBar, MessageBarTitle, MessageBarBody, Button } from '@fluentui/react-components'; import { DismissRegular } from '@fluentui/react-icons'; function Example() { return ( Descriptive title This is a message bar } />}> ) } ```
