Yes, if you build it with adapter-static, you can serve it with Apache as the built files are regular HTML/CSS/JS files. In short: SPA means it will run in the browser only, so it only contains HTML/CSS/JS files. Routing (navigating within the app to a different route) is done on the client side. SSR means the HTML is generated on the server-side, so you need to have a NodeJS running and serving your SSR application. I hope it helps you!
