What directory for Blynk apps on Raspberry Pi2?

I have the necessary Blynk libraries installed on a RaspberryPi running Jessie. I can run the blynk.js sample app and it connects correctly using a valid authorization token. However, which directory should be used for creating new apps? What permissions for the .js is required?

Thanks// Chris

Hello. Maybe I didn’t understand you correctly, but why that matter? You may use any directory I think.
