SignalR difference between On and Subscribe of IHubProxy

SignalR difference between On and Subscribe of IHubProxy

In SignalR, the On and Subscribe methods of the IHubProxy interface are used to subscribe to incoming messages from a SignalR hub. Here's an overview of the differences between these methods:

  • On: This method is used to subscribe to a specific event in the hub. You provide the name of the event as a string, and a callback function that will be called whenever the event is raised by the hub. The On method is typically used when you want to receive messages for a specific event or set of events.
hubProxy.On("eventName", data => { // Handle event data });
  • Subscribe: This method is used to subscribe to all events raised by the hub. You provide a callback function that will be called whenever any event is raised by the hub. The Subscribe method is typically used when you want to receive all messages from the hub, regardless of the event that raised them.
hubProxy.Subscribe(data => { // Handle event data });

In both cases, the callback function will receive the data associated with the event as its parameter.

Note that the On and Subscribe methods are used with the IHubProxy interface, which is used to interact with SignalR hubs from a client application. The server-side SignalR hub can raise events and send messages to connected clients, and the client can use the On and Subscribe methods to receive those messages.
