For some specific cases, SignalR offers a couple of native ways to deal with errors as follows:
We can supply a
promiseobject that SignalR returns. This means that we can either use
promiseobject returned when starting a connection to intercept errors during the connection process, or we can use
promiseobject returned during the remote invocation of a Hub method. By hooking a callback with these
fail()methods, we can be notified about the exceptions that occur during either the networking portion of a remote invocation or the server-side execution of a Hub method. We should observe that for errors occurring because of networking issues, SignalR...
