useNetwork

响应式网络状态。网络信息 API 提供了有关系统连接的信息，包括一般连接类型（例如：“wifi”、“蜂窝网络”等）。这可以根据用户的连接情况，用于选择高清内容或低清内容。整个 API 包括添加 NetworkInformation 接口和 Navigator 接口的一个属性：Navigator.connection。

用法

import { useNetwork } from '@vueuse/core'

const { isOnline, offlineAt, downlink, downlinkMax, effectiveType, saveData, type } = useNetwork()

console.log(isOnline.value)

若要作为对象使用，请使用 reactive() 进行包裹：

import { reactive } from 'vue'

const network = reactive(useNetwork())

console.log(network.isOnline)

组件用法

此函数也通过 @vueuse/components 包提供了 无渲染组件版本。了解更多关于用法的信息。

<template>
  <UseNetwork v-slot="{ isOnline, type }">
    Is Online: {{ isOnline }}
    Type: {{ type }}
  </UseNetwork>
</template>
