How can we get the transport method in javascript client for signalr core?

Question

In older versions of signalR, you could do this to get the transport method being used:

$.connection.hub.transport.name

How is this done for signalR core?

Answer 1

On the HubConnectionBuilder, you can get the transport like so:

this.connection = new signalR.HubConnectionBuilder()
    .withUrl(connectionUrl)
    .build();

this.connection.connection.transport.constructor.name

Perhaps not the best solution, but it seems to work well enough. Looks like the returned values could be:

• WebSocketTransport
• LongPollingTransport
• ServerSentEventsTransport
