Astro is great, using it for my blog site and. I have a mono repo setup React SPA and Astro For Blog. I can create a reusable component in React Repo and reuse in Astro blog.
You could also write native astro components which are very close to vanilla html css with added benifit of making reusable components and scoped css.
And you can also use svelte or vue components.
