Host a vanilla JS with fastify-vite

I was trying to host a Vite app with vanilla JS (frameworkless) SPA using [fastify-vite][], but all the examples are relative to frameworks and SSR.

Is there a way to achieve this, simply rendering the HTML and injecting the Vite-generated JS script without really relying to SSR?
