Hello there.
First of all, I really appreciate the amount of work you've put into overhauling this library!
I have previously been using the evs-broadcast fork of this lib in a project of mine and your version has addressed many of the issues I had experienced.
However, I am facing the following issue:
What's the problem?
Suppose there is a Node X which is already known to the consumer. The consumer queries the children of X by sending a getDirectory request to the provider. The provider tells the consumer that X has one child: The Node Y.
Now suppose that after some time, the provider creates an additional Node Z as a child of X. Since the consumer previously performed a getDirectory on X, the new child Z will be reported by the provider.
The EmberClient actually handles this correctly and adds Z as a child to X. However, there seems to be no (obvious) way to receive any sort of notification about this in the node-emberplus library!
The same applies to a scenario where Node Y is removed (isOnline=false).
I would have expected to be notified through the callback I can provide when calling EmberClient.getDirectory, but that only works for Parameter/Matrix nodes.
Why is it relevant?
I have a usecase where I need to "listen" for the creation and deletion of subnodes (actually subtrees in my case) below a certain Node. Everytime a subnode appears, I instantiate an object which serves as a functional representation of the structures below this subnode. Once the subnode disappears, I need to discard this instance.
How can it be reproduced?
- Connect to an Ember+ provider.
- Query the children of a node by sending a getDirectory request.
- Perform an action on the provider that causes children to appear (or disappear).
- Go sit in a corner and cry because the Node doesn't tell you anything about this! /s
