OnlineManager

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
• setOnline
• isOnline

onlineManager.setEventListener#

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)
  })
})

onlineManager.setOnline#

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)

Options

• online: boolean | undefined

onlineManager.isOnline#

isOnline can be used to get the current online state.

const isOnline = onlineManager.isOnline()
