I understand that when you create a new node, then you press "deploy" to generate the workflow and run it. But, is it possible to make a reactive workflow where the options (template) of one custom node depends on the previous nodes even if you didn't press "deploy" ?
For instance, I imagine a injection node that prompts a json with two values and you connect it to a custom node. Without pressing "deploy", the configuration template of the custom node will now have a drop-down where you choose among the provided possibilities.
I can imagine how to do this using context variables and making constant "deploys", but the fact of pressing "deploy" will kill the reactivity. Another possible solution would be a node that executes code in his configuration stage (before deployment), not sure if this can be done.
I guess a possible answer could be to make a custom UI or use node-red UI builder with a reactive js framework, but I just wanted to know what is the easier way to do a reactive workflow, or if this is even possible within this framework.
