How to pass node data to custom node (not React node)

[divq]

This tutorial introduces how to design your custom node:

My understanding is that, in order to make each node appear differently according to the node's internal state, you have to attach that specific state to the node's style attributes, and use the attributes to draw different nodes.

However in my situation, I want to use the node's data instead of style to draw different shapes (for example, draw ERD entities), but there are no extant methods to get that data.

I found that possibly I can get the graph from BaseElement's context, but I still need the node's ID to get the node's data.

In my situation, are the only viable methods the following two?

1. use React node ( which is not viable because my project is not a React project)
2. attach node's data to its style field.
