Vue.js serverPrefetch用法及代碼示例

interface ComponentOptions {
  serverPrefetch?(this: ComponentPublicInstance): Promise<any>
}

export default {
  data() {
    return {
      data: null
    }
  },
  async serverPrefetch() {
    // component is rendered as part of the initial request
    // pre-fetch data on server as it is faster than on the client
    this.data = await fetchOnServer(/* ... */)
  },
  async mounted() {
    if (!this.data) {
      // if data is null on mount, it means the component
      // is dynamically rendered on the client. Perform a
      // client-side fetch instead.
      this.data = await fetchOnClient(/* ... */)
    }
  }
}
