Answer 1

I just ran into the same issue. The jointjs DirectedGraph plugin requires the dagre and graphlib packages.

To get around this I npm installed both dagre and graphlib.

So you would need to do this...

import dagre from 'dagre';
import graphlib from 'graphlib';
import * as joint from 'jointjs';

joint.layout.DirectedGraph.layout(self.graph, {
    dagre: dagre,
    graphlib: graphlib
    setLinkVertices: false,
    rankDir: "LR",
    rankSep: 150,
    marginX: 100,
    marginY: 200,
    nodeSep: 80,
    edgeSep: 50
  }
  );
