Server-side rendering is not preconfigured.
Bellevue is well equipped for you to integrate SSR in a way that best suits your need, in case you need it. For advanced needs however, it might be a better idea to get started with Nuxt. To find out more about enabling SSR in a Vue app app, check out this official guide at ssr.vuejs.org.
Also keep in mind that some hosting providers offer prerendering as a service for single-page apps. See Netlify's documentation as an example.
