Electron: Trying to set `nativeTheme.themeSource`, but `nativeTheme` is undefined

Question

I\'m unable to set the themeSource of my electron app. Platform is Windows 8.1.

const electron = require(\'el         


        

Answer 1

nativeTheme = electron.nativeTheme;

This is the problem. You need to do:

const nativeTheme = electron.nativeTheme;

Although in this case there's no need for the extra variable - just do electron.nativeTheme.themeSource = 'dark';.

I strongly suggest you use Typescript - it would tell you this:

Edit: I'm sure I mentioned this in the comments but it seems to have been removed somehow: You also need to make sure you are using Electron 7.0.0 or greater - nativeTheme was not available before that.
