Differentiate live website and local website

This should be used only for very specific features. The local website is supposed to be an accurate preview for the client of what will be published and visible on the live website. So you should avoid having different behavior on the preview website and the live website

Inside the page, you can access the javascript variable window.galaxyInfo.live_website that will be true on a published website, and false on the local website

console.log(window.galaxyInfo.live_website)
