Is it possible to change a node input property at runtime, from the backend of the node? I tried using config.property = new\_value but it seems it is not correct.
Thank you,

A node is free to do whatever it wants with its internal configuration, but it cannot change the deployed flow configuration.

And more specifically, can you change the label of a node to be a value given by the backend. For example, in the backend a value is set in context.global, can it be accesed from the frontend?

No.
A node should not be using global context to store its own state.
The only mechanism available for the runtime to do anything to the editor is through the `node.status()` messages. Nothing else in the editor can be modified by the runtime.

I understand. Thank you for the explanations 🙂 !
