I want to know if we can implement flow based programming using a graph. Where each node is a process by itself, and the graph can be dynamic in nature. I’m not sure how I can achieve this in elixir. Please let me know your thoughts.

Take a look at the flow library. It might provide the tools you are looking for :slight_smile:.

flow isn’t related to the FBP paradigm

I still don’t quite get it. Are you intending each graph node as a state ? The edges as transitions to that state ?

I want to create something like this Each node being a function

Yes that looks very possible. If each node is a function you have the choice of having an Elixir process handle one function or you can mimic all of these within a FSM. Unfortunately Elixir doesn’t have a corresponding Erlang gen_fsm / gen_statem and will have to use the Erlang behaviours.

I think state machines aren’t the answer to this. As we might me dealing with a function which requires more than one input argument, and they are waiting for the output from a different node, which can be of asynchronous nature.
