elastic search node.js env on codeanywhere

I want to play around with a github project on codeanywhere. It's elastic search, node.js and vue.js. I have all the instructions for the project and have already installed node.js and dependancies but cannot get elastic search to work because the instructions tell me to use hosts: [ 'http://localhost:9200'] which is the default port for elastic search, but I am on a cloudide so it isn't working and not connecting
