Add run button on node.

[George-bai]

Hi @idling-mind, thanks for your awesome work. It that possible to add a small triangle run button at the right top corner of each node, and if the inputs are valid, the button is enabled, user can run single node one-by-one. this will be really useful when building a workflow. Thanks.

@George-bai thanks for your kind words.

Right now, when you run a flow, all nodes are executed. (there is a way to run only selected nodes also). However, from the server's persective, the operation is atomic. The server runs the flow and is back to it's initial state. This way it is able to serve multiple users at the same time.

When you are running nodes one by one, how would you manage the state of each node that has been already run? Should it be stored on the server or on the client side? If it has to be stored on the client side, then we cannot store large data. And we'll somehow have to communicate the current state of the runs to the server. If the state is managed on the server, we need to somehow identify each session and their individual runs/state and load and unload the state.

It is possible to implement this, however, may take some effort :)

Hi @idling-mind thanks for your prompt reply.

In my case, there will be always single user that editing the workflow at each time, so the sever can state at as-is state after each individual execution. All results and data are stored at the server side and the front side can indicate nodes that already executed ( by changing the node color?).

When build a complex data process workflow, it is really hard to build whole flow and then run & debug. Most cases, we will need to see the result from one node, then decide what to do next.
