Register Shape

You can refer to src/Shape/Nodes, src/Shape/Lines to register your own shape.

Registe React Node

extend VEditor.Default.Node please make the left-top point as the origin point (0,0)

editor.graph.node.registeNode("react-svg-node", {
  linkPoints: [{ x: 0, y: 0.5 }, { x: 1, y: 0.5 }],
  adsorb: [20, 12],
  render: render: (node: InstanceNode) => {
    const radius = 30;
    // popOver
    node.shape = node.shape ? node.shape : document.createElementNS('http://www.w3.org/2000/svg', 'g');
    ReactDOM.render(
      <>
        <circle className="svg-item-output" r={radius + 2} cx={radius} cy={radius} />
        <circle
          className="svg-item"
          r={radius - 1}
          cx={radius}
          cy={radius}
          style=
        />
      </>,
      node.shape
    );
    return node.shape;
  },
});
// result data

Registe Line

import { DefaultLine } from '@vesoft-inc/veditor';
const Path: DefaultLine.LineRender = {
  type: 'path',
  arcRatio: 4,
  ...DefaultLine,

  renderLabel(line: InstanceLine): SVGGElement {
    const { label, startStep = 1, endStep = 1, stepType, filter = [] } = line.data as VisualQueryLine;
    if(!line.label){
      line.label = document.createElementNS('http://www.w3.org/2000/svg', 'text');
    }
    line.shape?.appendChild(line.label);
    // do some thing to render label
    line.label.text = label;
    return line.label.labelGroup;
  },

  //if you need custom line path,override this method
  // render(line:InstanceLine){}
  
  checkNewLine(data: VisualQueryLine) {
    const { from, to } = data;
    if (from === to) {
      return false;
    }
    return true;
  },
};
editor.graph.line.registeLine('simple-label-line', Path);
