server sent events could potentially also be interesting
You are just talking about getting websocket messages if something happens on the server right - that would be the way to inform you similar to long-pulling.
It will look something like this:
Code
{
"subject": "xxxxxxxxx",
"data": {}
}Where data is any kind of json object and the subject would be a unique identifier for the data object
Interpretation than just would be something like (typescript/angular)
Code
private handleWsMessage(msg: WsMessageDto) {
switch (msg.subject) {
case WsSubject.Chat:
this.chatSubject.next(msg.data);
break;
case WsSubject.Transaction:
this.transactionSubject.next(msg.data);
break;
case WsSubject.Mail:
this.mailSubject.next(msg.data);
break;
}
}
