How do I get the current URL of my application?

Flow
1

I need the URL of my current application because I need to generate a link to another component of my website which is located on a subpath of my URL (e.g. the VAADIN application is under http://localhost:8080 and the other component is under http://localhost:8080/widget/?someCode=1

I want to provide the option to copy the URL to clipboard so you can paste it to OBS. How do I programatically get the “http://localhost:8080/” portion of that URL?

Solved by delegating the URL fetching to javascript with windows.location.href

3

There is a method on the page:

UI.getCurrent().getPage().fetchCurrentURL(url -> {
     // do something with it     
});
4

yes I tried that but it didn’t return anything but an empty string

5

though handling that in JavaScript now is actually the better approach as I’m calling JavaScript afterwards anyways to put the found url into clipboard. So I just altered that functionality to also fetch the url and do the splicing

If you do not need the URL on the server that sounds like a better approach. Pretty close to this one? https://cookbook.vaadin.com/copy-to-clipboard

yes exactly that one. copied the snippet from there and then prepend the given string with the URL I get from windows.location.href
