    Class DataArtifactViewerComponent

    Viewer component for Data artifacts.

    Displays tabular data using AG Grid via mj-query-data-grid. Supports two modes:

    1. Live data: When metadata.sql is present, executes the query dynamically via RunQuery({ SQL }) to fetch fresh data on each view. Falls back to inline rows on error.
    2. Inline data: Rows embedded directly in the artifact JSON (backward compat with older artifacts)

    The Query Builder agent emits artifacts with metadata.sql for live execution.

    Constructors

    Properties

    ActiveTableIndex: number = 0

    Index of the currently active table tab

    artifactVersion: MJArtifactVersionEntity

    The artifact version to display

    cssClass?: string

    Optional: Additional CSS classes to apply

    EffectiveSavedAtVersion: number | null = null

    The effective version number at which the query was last saved/updated. When viewing an older version, this looks ahead through newer versions to find the most recent savedAtVersionNumber for the same query, giving the user accurate context (e.g., "Query updated at v3" instead of the stale "Saved at v1" from this version's snapshot).

    ErrorMessage: string = ''
    GridColumnConfigs: QueryGridColumnConfig[] | null = null
    GridData: Record<string, unknown>[] = []
    HasError: boolean = false
    height?: string

    Optional: Custom height for the viewer (defaults to auto)

    IsLive: boolean = false
    IsLoading: boolean = false
    IsSaving: boolean = false
    LatestVersionNumber: number = 0

    Latest version number for this artifact (from cache)

    navigationRequest: EventEmitter<NavigationRequest> = ...

    Optional: Emitted when the plugin wants to navigate to a different app/nav item. Plugins that need app-level navigation (e.g., "Open Query" navigating to the Data Explorer's Queries nav item) should instantiate this emitter and emit a NavigationRequest. The event bubbles up through the artifact viewer chain to the host application where NavigationService handles the actual navigation.

    openEntityRecord: EventEmitter<
        { compositeKey: CompositeKey; entityName: string },
    > = ...
    PagerPageNumber: number = 1
    PagerPageSize: number = 100
    PagerTotalRowCount: number = 0

    Paging state — passed through to mj-query-data-grid's embedded pager

    Provider: IMetadataProvider | null

    If specified, this provider will be used for communication and for all metadata purposes. By default, if not provided, the Metadata and RunView classes are used for this and the default GraphQLDataProvider is used which is connected to the same back-end MJAPI instance as the Metadata and RunView classes. If you want to have this component connect to a different MJAPI back-end, create an instance of a ProviderBase sub-class like GraphQLDataProvider/etc, and configure it as appropriate to connect to the MJAPI back-end you want to use, and then pass it in here.

    QuerySyncState: QuerySyncState = 'no-query-latest'

    Query sync state — drives the toolbar UI for saved query actions

    readonly: boolean = true

    Optional: Whether the viewer is in readonly mode

    ResolvedTables: DataTable[] = []

    All resolved tables (from multi-table or wrapped single-table)

    SavingMessage: string = ''
    ShowSaveDialog: boolean = false
    ShowUpdateDropdown: boolean = false
    spec: DataArtifactSpec | null = null
    tabsChanged: EventEmitter<void> = ...

    Optional: Emitted when the plugin's additional tabs change after async loading. Plugins that load data asynchronously (e.g., from a component registry) should emit this when loading completes and new tabs become available. The parent panel listens for this to re-run change detection and render the updated tab list.

    "ɵfac": unknown

    Accessors

    • get hasDisplayContent(): boolean

      Whether this plugin has content to display in the Display tab. Used by the parent wrapper to determine if the Display tab should be shown.

      Subclasses should override this getter to return true when they have meaningful content to display.

      Default: false (subclasses must opt-in to showing Display tab)

      Returns boolean

    • get isShowingElevatedDisplay(): boolean

      Whether this plugin is showing an "elevated" display (e.g., extracted markdown/HTML) vs raw content. When true and content type is JSON, the wrapper will show a JSON tab.

      Subclasses should override this getter to return the appropriate value based on their current display state. For example, JSON plugin returns true when showing displayMarkdown or displayHtml, false when showing raw JSON editor.

      Default: false (showing raw content)

      Returns boolean

    • get parentShouldShowRawContent(): boolean

      Whether the parent wrapper should show a raw content tab (e.g., JSON tab for JSON content). This gives plugins fine-grained control over the parent's tab display.

      Use cases:

      • JSON plugin with extract rules: true (show JSON tab to view source)
      • Component plugin: true (show JSON tab even when displaying elevated component)
      • Code plugin: false (already showing raw content)

      Subclasses can override this to control parent behavior. Default: true (parent should show raw content tab if applicable)

      Returns boolean

    • get ProviderToUse(): IMetadataProvider

      Returns either the default Metadata provider or the one specified in the Provider property, if it was specified

      Returns IMetadataProvider

    • get RunQueryToUse(): IRunQueryProvider

      Returns either the default RunQuery provider or the one specified in the Provider property, if it was specified

      Returns IRunQueryProvider

    • get RunReportToUse(): IRunReportProvider

      Returns either the default RunReport provider or the one specified in the Provider property, if it was specified

      Returns IRunReportProvider

    • get RunViewToUse(): IRunViewProvider

      Returns either the default RunView provider or the one specified in the Provider property, if it was specified

      Returns IRunViewProvider

    • get SupportsFeedback(): boolean

      Whether this plugin supports user feedback. Plugins that return true will get a feedback button in the artifact viewer header. Override this getter to return true when feedback is available.

      Default: false

      Returns boolean

    Methods

    • A callback method that is invoked immediately after the default change detector has checked the directive's data-bound properties for the first time, and before any of the view or content children have been checked. It is invoked only once when the directive is instantiated.

      Returns Promise<void>
