Hi Stephen, This is incredibly cool to see!
I've always thought Node-RED was ripe for this kind of use but alas my own JS skills are too lacking to move strongly into this area. I'm very curious if you have thoughts in a similar direction I have contemplated: When I first learned about Node-RED, what I wanted was a way to show the status of bind()/connect() links between peers which were formed based on resolving abstract names to concrete ZeroMQ address strings stored in Zyre headers. (Maybe the most common Zyre usage idiom?). I also wanted a dynamic display that showed the status of the establishment of the links. Eg, after all the bind() calls, a Zyre peer is created and this leads to a newly displayed Node-RED node which shows bind()'ed addresses as "ports" on the node. Then after any successful connect() the peer somehow informs Node-RED and an edge from that node to the bound "port" is drawn. If the Zyre peer associated with a node leaves then the Node-RED node and its edges gets some indication (eg, redrawn with dashed lines) and after some longer time without reestablishment, redrawn in some more dire marking. That kind of thing. I think the information needed for such display is very application specific and some of it might be out-of-band of Zyre (or, could use Zyre chat) so probably it must require custom code somewhere. Maybe there could be some shared conventions developed along the way that different applications could adopt in order to exploit such a display. Given my lack of JS expertise, I don't know how much I could help realize this system, at least close to Node-RED parts. I do have C++/Python application support[1] for this auto-assembly of graphs of sockets via Zyre. It and I could serve as a test bed for developing some shared conventions. In any case, having this new Zyre layer in place goes a far way to making such a display. Nice job! Cheers, -Brett.
