    id: 'right',
    orientation: [1, 0],
    pos: [0, 0.5]
  },
  {
    id: 'left',
    orientation: [-1, 0],
    pos: [0, 0.5]

];

export default {

canvasData.render Render mode (two)

• Two modeString|Object

Object type (.vue) Recommended

// grid-node.vue
<template>
  <div class="grid-node">
    {{itemData.label}}
  </div>
</template>

<script>

export default {
  name: "grid-node",

  props: {
    // Here you can get the data of the current node in mockdata
    itemData: {
      type: Object,
    },
    // Native node data (not recommended)
    canvasNode: {
      type: Object
    }
  },
  methods: {
  },
  created() {

  }
};
</script>

<style scoped>
  .grid-node {
    width: 30px;
    height: 30px;
    line-height: 30px;
    text-align: center;
    border-radius: 50%;
    border: 1px solid #aaa;
    color: #FFF;
    background-color: #F66902;
  }

</style>

// component.js

<template>
  <div id="app">
    <butterfly-vue
      :canvasData="graphData"
    />
  </div>
</template>

<script>
import {ButterflyVue} from 'butterfly-vue';

import gridNode from './node/drag-node.vue';

export default {
  name: 'App',
  components: {
    ButterflyVue
  },
  data(){
    return{
      graphData: {
        groups: [],
        nodes: [
          {
            id: '0',
            left: 10,
            top: 10,
            label: '0',
            render: gridNode,
          }
        ],
        edges: [],
      },
    }
  },
}
</script>

String type（template）

// component.js

<template>
  <div id="app">
    <butterfly-vue
      :canvasData="graphData"
    />
  </div>
</template>

<script>
import {ButterflyVue} from 'butterfly-vue';

export default {
  name: 'App',
  components: {
    ButterflyVue
  },
  data(){
    return{
      graphData: {
        groups: [],
        nodes: [
          {
            id: '0',
            left: 10,
            top: 10,
            render: `<div>testNode0</div>`,
          }
        ],
        edges: [],
      },
    }
  },
}
</script>

• Because the String type uses runtime compilation, the following configuration needs to be enabled

//vue.config.js

module.exports = {
  runtimeCompiler: true
}

Function

Method	Description	Parameters
redraw	Redraw canvas	-

<template>
  <div>
    <button @click="redraw">Redraw canvas</button>
    <butterfly-vue
      ref="butterflyVue"
    />
  </div>
</template>

<script>
import {ButterflyVue} from 'butterfly-vue';

export default {
  name: 'Drag',
  components: {
    ButterflyVue,
  },
  methods:{
    redraw() {
      this.$refs.butterflyVue.redraw();
    },
  }
}
</script>

Custom Endpoint usage

<template>
  <div class="endpoint-node">
    <butterfly-vue-endpoint id="1" :param="{scope:'endpoint-1', limitNum: 2}"/>
    <butterfly-vue-endpoint id="2" className="endpoint-2">
      content
    </butterfly-vue-endpoint>
  </div>
</template>

<script>

import {ButterflyVueEndpoint} from 'butterfly-vue';
