useNetwork
Reactive Network status. The Network Information API provides information about the system's connection in terms of general connection type (e.g., 'wifi', 'cellular', etc.). This can be used to select high definition content or low definition content based on the user's connection. The entire API consists of the addition of the NetworkInformation interface and a single property to the Navigator interface: Navigator.connection.
Demo
isSupported: false
isOnline: true
saveData: false
type: 'unknown'
Usage
import { useNetwork } from '@vueuse/core'
const { isOnline, offlineAt, downlink, downlinkMax, effectiveType, saveData, type } = useNetwork()
console.log(isOnline.value)
import { useNetwork } from '@vueuse/core'
const { isOnline, offlineAt, downlink, downlinkMax, effectiveType, saveData, type } = useNetwork()
console.log(isOnline.value)
To use as an object, wrap it with reactive()
import { reactive } from 'vue'
const network = reactive(useNetwork())
console.log(network.isOnline)
import { reactive } from 'vue'
const network = reactive(useNetwork())
console.log(network.isOnline)
Component Usage
This function also provides a renderless component version via the
@vueuse/componentspackage. Learn more about the usage.
