This utility comes packaged with react-query and is available under the react-query/broadcastQueryClient-experimental import.


Import the broadcastQueryClient function, and pass it your QueryClient instance, and optionally, set a broadcastChannel.

const queryClient = new QueryClient()
broadcastChannel: 'my-app',



Pass this function a QueryClient instance and optionally, a broadcastChannel.

broadcastQueryClient({ queryClient, broadcastChannel })


An object of options:

interface broadcastQueryClient {
/** The QueryClient to sync */
queryClient: QueryClient
/** This is the unique channel name that will be used
* to communicate between tabs and windows */
broadcastChannel?: string

The default options are:

broadcastChannel = 'react-query',
