Build vs. Resources

[BrendanC23]

The react-ts boilerplate has both a build and a resources directory. Both of these have an icon.png file. Based on the electron-builder documentation, it looks in /build for the icon to use.

What is the purpose of having both build and resources folders? If I want to edit the icon for my app, do I need to update the icon in both locations?

The build dir is for electron-builder and will not be distributed. The resources dir for your app.

This is also unclear to me. I know the icons in the build folder are used by electron-builder to set the icon, but what is the purpose of importing an icon from the resource file into the createWindow function? It doesn't seem to do anything for me on mac.

Additionally, it's unclear to me how to change the app icon in a development build.
