Buffer() is deprecated

[haugerud]

Thanks for a nice piece of software!

Would it be possible to fix this issue? Or am I doing something wrong? No GUI appears when running the code.

I guess the deprecation part is just a warning. When testing 'hello world' the gui appears:

Hey, sorry just getting to this, this appears to be an issue with the node bonjour package, which hasnt been updated in 5 years...

[removogel]

Same to me. It worked very fine for 30 minutes. The i created a launcher entry for the AppImage and started it maybe a few times and had more than one instance running.
Now (even after system reboot) the application window stays empty, see screenshot.
At the same time i can still control the light via iOS app.

When starting from CMD i get following error

'/home/user/Apps/Keylight_Controller-x86_64.AppImage' 
Welcome to Node.js v14.2.0.
Type ".help" for more information.

@removogel

So the "Buffer() is deprecated" is a warning because of one of the dependencies being used for this app. And has always been there, and hasn't caused the app to not work.

I thought I had closed this issue previously, so if you wouldn't mind creating a new issue using the bug template so I could more directly support your issue you are experiencing

The problem is that newer nodejs versions now block execution.
