Hi,
- JSFBP is definitely on the "classical" FBP side of the house (as opposed to FlowHub), and I can probably help you there.
Actually, Flowhub is not classical or reactive. Or even an FBP runtime at all. Instead, it is an IDE for Flow-Based Programming that works across different languages and runtimes, both classical and reactive (assuming that they implement the FBP Protocol spec).
In that sense it is more like DrawFBP, allowing you to draw and manage FBP graphs for pretty much any flow-based environment.
However, thanks to the "live" protocol connection, it goes a bit further, allowing you to see what is happening inside a running FBP program, and depending on how far a given environment has implement the optional protocol features, can also create and edit new components right there in use, as well as run fbp-spec tests against them and the graphs.
Works also with JavaFBP, actually, if you install the FBP Protocol connector. 😉
