npm install for modules also needed?

[Joern]

Hello,

when do I need to run npm install?
Only one or also when I download modules from git afterwards?

I recall that this was asked inside modules folder sometimes in past or only once in MagicMirror folder is enough?

@Joern if the module supplies a package.json, then you should do npm install in the module folder
