I also recommend inertia.

It really doesn't do much, which is very refreshing coming from Nextjs.

It's simple tooling for backend for frontend-style APIs, taking care of basic routing, fetching of data, and submitting forms.

While inertia was invented for Laravel, I'd argue that it works even better with Adonisjs. Because Adonisjs is TypeScript you can infer the types coming from the backend.
