Ask HN: Modern Alternatives to Spas

Hello HN, I'm looking to start a new project and I'm curious to see if there are any alternative for modern web apps that don't fall into the SPA approach but still having a dynamic frontend with js and with page rendering fast. Specially if it's something that it's fast and easy to setup and has a built-in way or plug-in to authenticate users.

Maybe it's just too much to ask and a SPA with React or Vue with an API in the backend is still the best way to go.

I was imagining an ideal world where you could have a project quickly setup with Django and then a sparkling of Svelte here and there to enhance things up in your views.

Cheers
