ts
import { App, Rect } from 'leafer-ui'
const app = new App({ view: window, type: 'user' })
const backgroundLayer = app.addLeafer()
const contentLayer = app.addLeafer({ type: 'design' })
const wireframeLayer = app.addLeafer()
const background = new Rect({ width: 800, height: 600, fill: 'gray' })
const rect = new Rect({ x: 100, y: 100, fill: '#32cd79', draggable: true })
const border = new Rect({ x: 200, y: 200, stroke: 'blue', draggable: true })
backgroundLayer.add(background)
contentLayer.add(rect)
wireframeLayer.add(border)add(leafer: Leafer)
