The existing subflow capability in node-red serves a purpose, but is need of further development to be truly useful.
The follow design outlines where we'll go next with subflows.
There are three types of subflow:
-
inline-subflow: a subflow that is defined and used once within a single flow. It is not reusable. Inputs: 0/1, Outputs: 0/n -
loop-subflow: a subflow that defines a condition under which a message is iterated on. Inputs: 1, Outputs: 1 -
template-subflow: a subflow that is added to the palette as a reusable set of nodes. This is equivalent to what we have today. Inputs: 0/1, Outputs: 0/n. It defines a set of properties of its nodes that can be customised by individual instances.
A new subflow node is []!
