How can I detect if a page was generated on-request or on-build when using hybrid output?

Hi @dense mural. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

In Astro's hybrid output mode, you can control whether a page is pre-rendered or generated on-request by using the prerender export in your page or endpoint.

To pre-render a page (generate it at build time), you can add export const prerender = true to your page or endpoint. This means that the page will be generated at build time and served statically.

// This route should be generated at build time!
export const prerender = true

On the other hand, if you want a page to be generated on-request (not pre-rendered), you can add export const prerender = false to your page or endpoint. This means that the page will be generated on-demand, at the time of the request.

// Mark the page as `prerender = false` to skip pre-rendering
// and run the API endpoint in the server on every submission.
export const prerender = false

Please note that in hybrid mode, pages are pre-rendered by default. So, if you don't specify prerender export, the page will be pre-rendered.

However, there's no built-in way to detect at runtime whether a page was pre-rendered or generated on-request. The `prerender` export is a build-time setting that controls how the page is generated, but it doesn't provide any runtime information.
