The artifact version to display
OptionalcssOptional: Additional CSS classes to apply
OptionalheightOptional: Custom height for the viewer (defaults to auto)
OptionalnavigationOptional: 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.
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.
Optional: Whether the viewer is in readonly mode
OptionaltabsOptional: 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.
StaticɵcmpStaticɵdirStaticɵfacRehydrated board engine for export/snapshot duty (null when content is malformed).
Raw board payload fed to the snapshot component (setter-driven re-parse there).
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)
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)
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:
Subclasses can override this to control parent behavior. Default: true (parent should show raw content tab if applicable)
Returns either the default Metadata provider or the one specified in the Provider property, if it was specified
Returns either the default RunQuery provider or the one specified in the Provider property, if it was specified
Returns either the default RunReport provider or the one specified in the Provider property, if it was specified
Returns either the default RunView provider or the one specified in the Provider property, if it was specified
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
Ask the user for feedback on the current artifact. Called by the artifact viewer panel when the user clicks the feedback button in the header. Each plugin implements its own feedback UX (dialog, panel, inline form, etc.).
Default: no-op. Subclasses should override to implement artifact-type-specific feedback.
OptionalGetGet additional tabs that this plugin wants to provide to the artifact viewer. Override this method to provide custom tabs for viewing metadata, code, etc.
Array of tab definitions, or undefined if no additional tabs
ProtectedgetGet the content from the artifact version. Handles both string content and JSON objects.
Return a point-in-time snapshot of the data this viewer is currently displaying. Every viewer plugin MUST implement this with type-appropriate content.
Guidelines for file-based viewers:
A DataSnapshot describing the current state, or null if no data is available.
ProtectedgetGet the description
ProtectedgetGet a safe display name for the artifact version
ProtectedgetGet a display-friendly title for the artifact. Returns null if no name is available.
ProtectedgetGet the raw text content from the artifact version. Returns null if no content is available.
OptionalGetGet list of standard tabs that this plugin wants to hide/remove. Use this when the plugin provides custom alternatives to standard tabs.
Example: Component viewer provides custom "Resolved JSON" tab, so removes standard "JSON" tab
Array of standard tab names to remove (case-insensitive) Valid values: 'JSON', 'Details', 'Links' Note: 'Display' cannot be removed (it's the main view)
Download the board as one self-contained HTML document.
Download the board as a standalone SVG document.
Print the board: open a blank window, write the self-contained export document and invoke the print dialog (same precedent as the live board host's print path). When the popup is blocked this is a logged no-op — nothing breaks, the user can retry.
ProtectedparseProtectedtriggerTrigger a browser file download from a URL. Shared by all file-backed viewer plugins (PDF, XLSX, DOCX) so the fetch → blob → object-URL → anchor pattern lives in exactly one place.
ARTIFACT VIEWER PLUGIN for saved whiteboards — renders the session-channel board artifact (a WhiteboardState.ToJSON payload) as a read-only snapshot with the same export affordances the live board offers (Download HTML / Download SVG / Print).
Resolved dynamically by the artifact plugin host via the MJ ClassFactory (keyed by the artifact type's DriverClass), which instantiates the class ONCE with a bare
