Question 1

How to set wallpaper on multiple screens in macOS with wallpaper module?

Accepted Answer

Use the screen: 'all' option in setWallpaper to target all displays. On Linux and Windows, this isn't supported—it defaults to the main screen only.

Question 2

Can I set a solid color wallpaper on Windows using this module?

Accepted Answer

No, setSolidColorWallpaper is macOS-only. For Windows, you'd need to create an image file with the desired color and set it via setWallpaper or use native tools.

Question 3

Wallpaper module vs native shell commands for automation?

Accepted Answer

Wallpaper simplifies cross-platform scripting with a consistent Node.js API, but native commands might be lighter for single-OS scripts without Node.js overhead. Choose based on portability needs.

Question 4

How to handle errors if setting wallpaper fails in Node.js?

Accepted Answer

Wrap the setWallpaper call in a try-catch block to manage promise rejections, and check file paths or permissions, as the module doesn't provide detailed error handling beyond standard promises.

Question 5

Is wallpaper module compatible with Electron apps?

Accepted Answer

Yes, it works in Electron since it's a Node.js module, but ensure proper permissions for file access and consider sandboxing limitations on different platforms.

Question 6

What image formats are supported for setting wallpapers?

Accepted Answer

The module relies on OS capabilities, so common formats like JPEG, PNG, and BMP should work, but check platform-specific documentation for any restrictions.
