extract host name of the node-red host, with JS ?

[Jéan Roux]

Hi, can I get the host name of the underlying server to nodered with Javascript, that I can use in a function node? I tried 

msg.payload = location.host ;

as per normal JS, but this does not work?

one way is to include the "os" library in the functionGlobal section of your settings.js

    os:require('os')

then you can use a function node with something like

  msg.payload = context.global.os.hostname();
