What is the best way to implement page loading without reloading?

Question

Angular

Good afternoon!
There is a site https://www.rezo-zero.com/ . It is necessary to implement similar transitions between pages without reloading.
I am developing sites on Wordpress, I think, can this be done in a good way using ajax requests? Or is it better to do such chips in angular?

Answer 1

"What to use for animation: a data transfer protocol or a one-page framework."
I'm actually lost....

Answer 2

The transition from page to page without reloading is implemented by the JS history API + fetch API, but I used to look in the direction of any SPA framework (angualr, vue + vuex, React to the extreme) + https://v2.wp-api.org/ if you need to migrate wordpress site.
