0 I would like to listen to path changes in a SPA which is not maintained by me. I found one solution here: https://stackoverflow.com/a/44819548/7042552 But still, it seems kind of "hacky" to me - but still my implementation is like this: let url = window.location.href; ['click','popstate', 'onload'].forEach( evt => window.addEventListener(evt, function () { requestAnimationFrame(()=>{ if (url !== location.href) { // do stuff } url = location.href; }); }, true) ); Is there a better or more generic way to listen for page loads in a SPA?
