The OnlineManager manages the online state within TanStack Query.
It can be used to change the default event listeners or to manually change the online state.
Its available methods are:
setEventListener can be used to set a custom event listener:
import NetInfo from '@react-native-community/netinfo'
import { onlineManager } from '@tanstack/react-query'
onlineManager.setEventListener(setOnline => {
return NetInfo.addEventListener(state => {
setOnline(!!state.isConnected)
})
})
import NetInfo from '@react-native-community/netinfo'
import { onlineManager } from '@tanstack/react-query'
onlineManager.setEventListener(setOnline => {
return NetInfo.addEventListener(state => {
setOnline(!!state.isConnected)
})
})
setOnline can be used to manually set the online state. Set undefined to fallback to the default online check.
import { onlineManager } from '@tanstack/react-query'
// Set to online
onlineManager.setOnline(true)
// Set to offline
onlineManager.setOnline(false)
// Fallback to the default online check
onlineManager.setOnline(undefined)
import { onlineManager } from '@tanstack/react-query'
// Set to online
onlineManager.setOnline(true)
// Set to offline
onlineManager.setOnline(false)
// Fallback to the default online check
onlineManager.setOnline(undefined)
