import vue3ResizeDrag from 'vue3-resize-drag'
const app = createApp(App)
app.use(vue3ResizeDrag)

## 组件用法
```

        v-for="item in data.data" 
        :key="item.name" 
        :x="item.x"   <!-- x 为组件left位置 -->
        :y="item.y"   <!-- y 为组件top位置 -->
        :w="100"  <!-- 组件宽度 默认为100 -->
        :h="100"  <!-- 组件高度 默认为100 -->
        :zIndex="1"  <!-- 组件层级大小 -->
        @moveHandler="moveHandler"  <!-- 组件移动回调 -->
        @mouseUpHandler="mouseUpHandler"  <!-- 组件移动结束回调 -->
        @downHandler="downHandler"  <!-- 移动开始之前回调 -->
        :isDraggable="item.drag"  <!-- 是否可移动 默认为true -->
        :isResizable="item.resize"  <!-- 是否可缩放 默认为true -->

        :rotate="0"  <!-- 旋转角度 默认为0 -->
        @resizeHandler="resizeHandler"  <!-- 缩放回调函数 -->
        @rotateHandler="rotateHandler"  <!-- 旋转回调函数 -->
        :resizeIconSize="8"  <!-- 缩放按钮大小 默认为8px -->
        :isGuide="true"   <!-- 是否开启辅助线 默认为false -->
        :guideStyle="{}"  <!-- 辅助线样式 -->
        @activated="activated"  <!-- 激活回调函数 -->
