.background color modifier

[AndrewSB]

It would be nice to have a .background(Color.red) operator on a view, that sets the .backgroundColor of the ASDisplayNode. Is there a technical reason this isn't already in the library? If not, could that operator be added?

Hi, thanks!
The reason why we can't use such as adding background what we want is Texture's layout spec is only for layout information. We must avoid to create a node inside returning layoutspec.

This issue also helps you to understand.

Or even if you mean that operator sets the background color of the node, that's not also a good practice.
While creating layout spec, as possible, we should keep the state of the nodes.

got it, there's that technical limitation I was looking for. apologies for not searching the issues before creating a new one, and thank you for your work building this!

actually, as I'm looking through your demo, would it not be possible to wrap onDidLoad in a special modifier to just change the background color? like you've done here:

why is it a best practice to enforce that operators only modify the layout, not node style/state? does modifying state/style cause a re-render?
