Error: getaddrinfo ENOTFOUND in nodejs for get call

Check host file which like this

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255 broadcasthost

getaddrinfo ENOTFOUND means client was not able to connect to given address. Please try specifying host without http:

var optionsget = {
    host : 'localhost',
    port : 3010,
    path : '/quote/random', // the rest of the url with parameters if needed
    method : 'GET' // do GET
};

Regarding learning resources, you won't go wrong if you start with http://www.nodebeginner.org/ and then go through some good book to get more in-depth knowledge - I recommend Professional Node.js , but there's many out there.
