Electron Desktop App Development · Lesson

Theming and Dark Mode Support

Add native light and dark theming to your Electron UI using the nativeTheme module and CSS variables, complementing your existing UI-building skills.

Why Theming Matters

Desktop users expect apps to respect their system theme. A polished Electron app switches between light and dark automatically.

Electron exposes nativeTheme in the main process to read and control the OS appearance.

const { nativeTheme } = require('electron');
console.log(nativeTheme.shouldUseDarkColors);
