rune-langium / visual-editor/src / RuneTypeGraphRef

Interface: RuneTypeGraphRef

Defined in: packages/visual-editor/src/types.ts:528

Imperative ref handle for RuneTypeGraph.

Remarks

Obtain via React.useRef<RuneTypeGraphRef>() and pass as ref to <RuneTypeGraph ref={ref} />. All methods are synchronous except exportImage().

Pitfalls

• relayout() triggers a full Dagre computation — avoid calling it in rapid succession (e.g., in a useEffect with frequent deps). Batch layout updates with a debounce.
• exportImage() renders the current viewport — hidden nodes (filtered out) will not appear in the export.

Methods

exportImage()

exportImage(format): Promise<Blob>;

Defined in: packages/visual-editor/src/types.ts:536

Parameters

Parameter	Type
format	"svg" | "png"

Returns

Promise<Blob>
