Hi @bhepler thanks for the answering… so as i can see if i dont have the Pi i cant check if its working,isnt it? Thanks again

Of course you can. Just install node.js on your windows machine, clone the magicmirror package, install it and start developing. There is an instruction here: https://forum.magicmirror.builders/topic/548/building-mirror-without-programing/2

I installed it some days ago on a spare windows 7 laptop without any issues.
The only thing you can’t do is accessing GPIO ports … of course, because your windows machine does not have these.

bhelper’s answer to question 3 was to access your mirror once your raspberry is running.

To answer your questions:

1. Yes
2. Yes
3. Yes

I use IntelliJ IDEA on Windows 10 to modify my config file via a shared folder on the Pi. But you can certainly upload any script to your Pi with WinSCP or other similar program. Dreamweaver should be just fine. The MagicMirror code is mostly Javascript. Since it’s interpreted code and not compiled, you shouldn’t have to worry about whatever tool you use to modify the script files.

Yes, you can use Chrome to test your output. At the top of the config.js file will be the port that the mirror will be accessible. Just point your Chrome browser to http://[raspberry IP address]:[port]/ and you’ll see the interface in your web browser.
