How to stretch node width to viewport width in Javascript Diagram?

To stretch a node’s width to fit the viewport width, you can adjust the node size based on the diagram’s viewport settings.The viewPortWidth and currentZoom properties within the diagram’s scrollSettings help you calculate the appropriate node width, ensuring it aligns with the visible area of the diagram.

Below Code Snippet explains how to stretch node width to viewport width

function updateImageNode() {
 let node = diagram.getObject('headerNode');
 node.width =
   diagram.scrollSettings.viewPortWidth +
   diagram.scrollSettings.viewPortWidth * diagram.scrollSettings.currentZoom;

 // Lock the zoom level to maintain a consistent view
 diagram.scrollSettings.maxZoom = diagram.scrollSettings.currentZoom;
 diagram.scrollSettings.minZoom = diagram.scrollSettings.currentZoom;
} 

The updateImageNode function sets the headerNode width to account for the viewport width and current zoom. It then locks the zoom level by setting maxZoom and minZoom to the current zoom, maintaining a consistent view.
