import from '@/pages/my'
import Cart from '@/pages/cart'
import Order from '@/pages/order'
import TMap from '@/pages/map'
import New from '@/pages/new'

const My = r => require.ensure([], () => r(require('@/pages/my')), 'my')
const Cart = r => require.ensure([], () => r(require('@/pages/cart')), 'cart')
const Order = r => require.ensure([], () => r(require('@/pages/order')), 'order')
const TMap = r => require.ensure([], () => r(require('@/pages/map')), 'map')
const New = r => require.ensure([], () => r(require('@/pages/new')), 'new')

}
