Question

If you send a notif to a user and he is offline, he can't receive this notif when he reconnect.

When sending notifications in DeepstreamIO, if a user is offline and later reconnects, he will not see the notification. In addition to that records is empty. Can you please suggest any solution?

I try to send notifications to many users, I found that if I send for example 3 notifs the user received the last one, but if he is offline and the reconnect, he can't notify.

Hi, you seem to be mixing some concepts.

In deepstream you can send events : connected user subscribes to the topic and therefore can receive messages emmited under that topic. If he is not subscribed, or not connected the server, he won't receive the event.

Another concept are records, which are JSON documents that can be persisted to database and to which one can read/write and subscribe in order to receive notifications when the record changes.

If you want messages to persist, you must use a record.

I suggest going through the documentation at https://deepstreamio.github.io
