Get MAC addresses of host network interfaces in Node.js

 node-macaddress is a nodejs library that retrieves the MAC addresses
 (hardware addresses) of the host's network interfaces.
 It provides a convenient wrapper of os.networkInterfaces() call.
 If the host system has more than one network interface, it will
 automatically pick one appropriate interface if you'are only interested
 in one MAC address identifying the host system.
 Node.js is an event-based server-side JavaScript engine.
