Bridging two realms/subscribing one client to multiple realms
Yes, the simplest thing that could possibly work is to open two WAMP clients - one for each realm.
I'm looking into designing a WAMP/Crossbar application with two or more realms; one realm would be for backend messaging, while a second would essentially expose a public API to frontend clients. Now, at some point messages need to cross between realms, which would require one client to join two realms and act as a bridge.
Is that feasible at all without a lot of bending over backwards? Or is the design approach flawed from the beginning, and I should rather use specific topic URIs to separate front and backends?
