Why not unify this in front-end and back-end, we can only keep one field in TaskNode.

good idea, let me try it

[unigof]

I think TaskNode just used in back-end when workflow running, in front-end it use taskDefinitionJson to represent task node in dag. And I searched ui module and not found TaskNode to use.

could you have a time to review this pr? thx~ @SbloodyS @ruanwenjun

And I would like to use predecessors to represent the upstream node, depList is confused with dependent node.
