how to work with realtime?
hello everyone, I opened the realtime documentation, but I didn't understand how to work with it. It seems to show how to create an object, but how to use it and get, say, there is no value from the database
TL;DR
Learn to work with real-time updates by creating a document accessible to users. Set up a subscription that triggers an event when the document changes. Use Realtime's subscribe function in client code, like the Kotlin example provided, to listen for updates from the database and perform actions, such as logging the new data.
It seems to show how to create an object
what do you mean?
TypeScript
suspend fun getRealtime(onUpdate: (Notification) -> Unit) {
val realtime = Realtime(client)
val subscription = realtime.subscribe("databases.$databaseId.collections.Notification.documents") { event ->
val payload = event.payload
Log.d("REALTIME_DATA", "new message: ${payload}")
}
}
this
yes, so that subscribes and when an event comes in, it gets logged
Docs say:
Instead of requesting new data via HTTP, the subscription will receive new data every time it changes
how can this be used?
create a document that the user has access to and the event will come through.
and how do I output the document I need if there are no changes, but they will be?
