Network

Connection state and reachability

Connection state through One.Network. Backed by NWPathMonitor on iOS, ConnectivityManager with a NetworkCallback on Android, and navigator.onLine with online/offline events on web.

import { One, useNetworkState } from 'one'
import { Text } from 'react-native'

const state = await One.Network.getState()
// { type: 'wifi', isConnected: true, isInternetReachable: true }

const subscription = One.Network.addStateListener((next) => {
  console.log(next.type)
})
subscription.remove()

function NetworkStatus() {
  const live = useNetworkState()
  return <Text>{live.type}</Text>
}

type is one of none, unknown, cellular, wifi, bluetooth, ethernet, wimax, vpn, or other. On web a live connection reports unknown, since browser connection types are unreliable.

The library manifest declares ACCESS_NETWORK_STATE (a normal install-time permission, merged into the app automatically).
