@dobbel I used the latest EAP for IntelliJ Ultimate (why limit myself to PHPStorm when I can have everything for free :P)
I added chrome debug extension (all I needed to do was right click the icon and click Inspect in IDEA with IDEA running, and my breakpoints worked) and also xdebug helper (all I needed to do was left click on the icon and click Debug, then click Run->Start Listening for PHP Debug connections - it auto-detected the corresponding file in my project which was symlinked into my localhost Apache www root when it hit the breakpoint). I’m not sure about node.js server side debugging though (my APIs are developed in PHP as I use shared hosting). I’ll probably try debugging electron next. Cordova debugging in IDEA doesn’t seem possible yet, though (hope someone will come up with a guide for that).
