SPA moves all the routing/templating to the browser side.

server side rendering does it all on the server and spits out html(legacy cgi style)

between these two: static html template downloaded from the server, then use ajax to update json in the html pages, which is the old boring way but it might still be the best middle ground?

Unless I need make a desktop complex GUI program where SPA could be a reasonable choice, I will just do the html/ajax old way, not fully geared towards to server or client side rendering, life is much easier.
