Trying to set up Strapi - completely lost!

Hi all, I’ve been using Strapi locally with Node.js and was getting along fine, so I decided to try going online using Digital Ocean. I can’t figure out what’s needed to get up and running. When using my local Strapi I simply set up the api using

const axCommInstance = axios.create({

  baseURL:'http://localhost:1337/'

});

then to fetch the relevant content:

let response = axCommInstance.get('rfm-001-home-jumbo') 
        .then(function (response) {
            console.log('Dumping Response Data');
            setStrapiData(response.data);
            })
        .catch(function (error) {
            console.log(error);
        });

This returns the contents of the Single type which can then be displayed. I assumed that I would be able to do the same thing with the hosted Strapi by simply replacing the baseURL with the new one referring to the Digital Ocean host. If this is the case can someone please tell me where to find the url, and if not then what additional setup and coding steps are required in order to make the connection? Thanks very much in advance, Dan.
