How to Stretch Node Width to Viewport Width in React Diagram?

This article explains how to stretch a node’s width to fit the viewport width in React 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 = diagramInstance.getObject('headerNode');
   node.width =
     diagramInstance.scrollSettings.viewPortWidth +
     diagramInstance.scrollSettings.viewPortWidth *
       diagramInstance.scrollSettings.currentZoom;

        //to preview zoom in and zoom out
       diagramInstance.scrollSettings.maxZoom = diagramInstance.scrollSettings.currentZoom;
       diagramInstance.scrollSettings.minZoom = diagramInstance.scrollSettings.currentZoom; 
 }
