I have a javascript widget (script1) that's placed in the <head> on customer's websites. This creates an iframe, in which script2.js is located.
These two scripts talk to each other via postMessage. I have implemented a way where script2 asks the current URL from script1, which then passes back the value of window.location.href.
This works fine in Gatsby, but I discovered it doesn't work in React with Flux.
I'm not too familiar with these frameworks, but I guess this is because in such a SPA the script is loaded once.
How do scripts like Google Analytics get around this issue? How do they detect a page change and send the correct URL when that happens? Would love to understand more about how this works.
