useBroadcastChannel
Reactive BroadcastChannel API.
Closes a broadcast channel automatically component unmounted.
Usage
The BroadcastChannel interface represents a named channel that any browsing context of a given origin can subscribe to. It allows communication between different documents (in different windows, tabs, frames, or iframes) of the same origin.
Messages are broadcasted via a message event fired at all BroadcastChannel objects listening to the channel.
import { useBroadcastChannel } from '@vueuse/core'
import { shallowRef } from 'vue'
const {
isSupported,
channel,
post,
close,
error,
isClosed,
} = useBroadcastChannel({ name: 'vueuse-demo-channel' })
const message = shallowRef('')
message.value = 'Hello, VueUse World!'
// Post the message to the broadcast channel:
post(message.value)
// Option to close the channel if you wish:
close()
