Astro 2.9

A new version of Astro has just been released with a long-awaited experimental feature: View Transitions. This makes it easy to create fluid, animated transitions between HTML pages, without having to resort to client-side routing: there's no need for a <Link> component as with Next.js or Remix. For a React developer, this makes the framework more appealing and competitive in terms of UX compared with the classic SPA mode we're used to, while keeping a model simpler. Careful: these transitions won't preserve your React state across navigation, which could be a problem. Note support View Transitions remains weak, but is making rapid progress and can be considered as a progressive enhancement, plus Astro offers a fallback mode.

Solito 4

New version of the project that unifies React-Native and Next.js under shared abstractions. With v4, it is now possible to use Next.js App Router. New APIs have been introduced for this purpose. Note that React-Native does not yet support React-Server Components: it is still a bit early to be able to use them in a cross-platform way.
