Await signalr message in client - websocket

Question

Is it possible for a SignalR client send a message to the server and then to await for a seperate message (not a return value) from the server?
The theory;
Client1 send message1 to Server and "waits" for the response.
Server processes some logic
Server sends message2 to Client1 and Client1 executes the waiting code.
Call to the server:
$.connection.myhub.server.myRequest(id).done(()==>{
// myRequest is done;
// the server has received the request but hasn't processed it yet.
// I want put some *async* code here to do something when the server has triggered $.connection.myhub.client.myResponse(id, someParam);
});
Callback to the client:
$.connection.myhub.client.myResponse(originalId, somePassedBackValue);
Can I use Async/Await, or wrap this in a Promise somehow?
If this isn't acheivable in SignalR are there anyother socket libraries that might be used instead?

Answer 1

You can do something, like the following:
Imagine you have a client that joins a group, updates a table and then notifies the client that it has joined.
Client
msgHub.server.joinGroup(id).done(function () {
console.log("Joined Group");
serverCallFinished = true;
})
msgHub.client.displayTable = function (table) {
display(table);
}
Hub
public async Task JoinGroup(string practiceId)
{
try
{
await Groups.Add(Context.ConnectionId, practiceId);
//Add new table
var table = new Table(practiceId)
await UpdateTable("SomeGroup", table);
}
catch (Exception e)
{
throw;
}
}
public async Task UpdateInfo(string groupName, string table)
{
//await some logic
Clients.Group(groupName).updateTable(table);
}
Update info will call the client with message2 in this case a table that it wants to display to the client. When it finishes the it will return from its awaited state by JoinGroup which will return and alert that a new user has joined a group.
