How to dynamically change the url when opening modal windows, as well as open another page using this URL?

Question

Vue.js

Good afternoon!
Recently I came across the site https://dropsearn.com/

The bottom line is that all the content of the site is presented in modal windows, but when opening a record in the modal window, the url dynamically changed.
You can also go to this URL and open an SEO page like https://dropsearn.com/events/wunderbit-ambassador-... The

question is how to do this? Thanks in advance for any help!
