import { TCartType } from '@src/types/basic'

const props = defineProps({
  data: {
    type: Object,
    default: () => {},
  },
})

这个data的类型怎么能用引入的TCartType呢？

import { TCartType } from '@src/types/basic'
import { PropType } from 'vue'

const props = defineProps({
  data: {
    type: Object as PropType<TCartType>,
    default: () => {},
  },
})

interface Props {
    data?: TCartType
}

const props = withDefaults(defineProps<Props>(), {
    data: {
        tip: '默认值'
    }
})
