Realtime: there is no dedicated object to manage connections

No description provided.

Ok, this in itself is not necessarily an issue, however are you therefore implying that all of RTN* cannot be supported, without a refactor i.e. we need a Connection object, but whether it is managed with a ConnectionManager or a state machine for example, is not necessarily part of the spec.

[ricardopereira]

@mattheworiordan There is no Connection object either. The Realtime client instances a Transport object and connects to the server with the current WebSocket. Just one connection per client.

[mattheworiordan]

@ricardopereira that is fine, other than the ably-js library, there is only ever one transport open using WebSockets, and in all libraries there is only ever one Connection open as well. As a workaround, we could perhaps simple create a Proxy Connection object that exhibits the properties described in the spec, but simply references the attributes in the Client itself. That way, we don't need to refactor now, and can easily do it later without changing the interface. WDYT?

Well, the connection is handled on the ARTWebSocketTransport. I can add a protocol to mirror the existing methods from ARTRealtime. Like you said, a proxy Connection object. It's the best workaround.

BTW. What happens when the transport is closed & re-opened (such as connection failure), does the ARTWebSocketTransport remain consistent or is a new object created each time?

The object remains consistent.

Ok, great, well lets go with a proxy object for now as that will allow us to meet the requirements of the spec easily
