I can parse are HTTP response of one of the intial calls and save that in the state but there must be another way to get the URL?
I am using the npm 'rest' library and want to specify a different port but I do not know the path on which machine the server will be installed so I need the server's url.
Solution
window.location.hostname

Use the window object to get the current URL in React, e.g. window. location. href returns a string containing the whole URL. If you need to access the path, use window.
Using location props location. pathname can get you the current URL pathname inside a React component.
To display an image from a URL, use the img tag and set its src prop to the complete URL of the image. Optionally set the alt prop to a short description of the image.
location is a property on the window object with a bunch of information, you can get the url with window.location.href
You can get the hostname with window.location.hostname
