Recently I spent a couple days building the same web app in Next, Nuxt, and SvelteKit just to get a feel of how to build a web app today. The web app was pretty basic. A couple of pages showing data from different apis and auth with user setting page.
My favorite by far was SvelteKit despite being the one with the smaller community. It was actually enjoyable compared to the others. It was very easy to feel like I was actually building something. You feel productive right away. The app automatically felt well organized with how the file layout was. Everything belong in a specific place. Layout goes here, Server stuff goes there, pages go here. Even form processing with nice. Building components was like building components in regular JS.
Next was my least favorite mostly due to the syntax and how you had to build the application. I really didn't like the whole style of Next and React. Just felt dirty.
I would highly suggest people to try SvelteKit. The file names might be a bit weird but it will teach you to use file finder in your IDE.
