我是使用的vue,所以,

第一步:先安装 Dagre and Graphlib 依赖

npm install dagre 

npm install @dagrejs/graphlib

第二步:引入

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

第三步:使用

this.graph = new joint.dia.Graph;
this.paper = new joint.dia.Paper({
  el: document.getElementById('model'),
  model: this.graph,
  width: "100%",
  height: 500,
  gridSize: 1,
});
 
//注意:这个要放在生成节点之后的位置,否则不会生效
例如
var rect = new joint.shapes.standard.Rectangle();
rect.addTo(this_.graph);
 
joint.layout.DirectedGraph.layout(this.graph, {
  dagre: dagre,
  graphlib: graphlib,
  setLinkVertices: false,
  rankDir: "TB", //节点方向 有几个选项 "TB" (top-to-bottom) / "BT" (bottom-to-top) / "LR" (left-to-right) / "RL" (right-to-left)
  align:"UL",
  rankSep: 150, //节点方向 有几个选项 TB / BT / RL / LR
  marginX: 100,
  marginY: 200,
  nodeSep: 80,
  edgeSep: 50
});
