Summary

I have some pages being ISR instead of SSG even without revalidate in getStaticProps.

How to force them being SSG and not ISR on build time?

Context

I have a [...path].tsx file that uses getStaticPaths and getStaticProps. When I run yarn build it even shows me the SSG ●


I realise this might be ISR, but this is the message shown on build:

●  (SSG)      prerendered as static HTML (uses getStaticProps)
   (ISR)      incremental static regeneration (uses revalidate in getStaticProps)

I don't have revalidate anywhere

export const getStaticPaths: GetStaticPaths = async (context) => {
  const cmsPaths = await fetchCmsPaths()
  const locales = context.locales || []

  const paths = cmsPaths
    .filter((path) => path !== "/" && path !== "/404" && path !== "/500")
    .map((path) => locales.map((locale) => ({
        params: { path: path.split("/").filter(Boolean) },
        locale,
      })),
    ).flat()

  return { paths, fallback: "blocking" }
}

export const getStaticProps: GetStaticProps<ContentPageProps> = async (
  context,
) => {
  const segments = context.params?.path as string[]
  const path = segments.map((segment) => `/${segment}`).join("")

  const cmsPage = await fetchCmsPage({ path })

  if (!cmsPage) { 
    return { notFound: true }
  }

  return { props: { cmsPage } }
}

When I visit the .next/server/pages folder, instead of having the pre-built HTML (like my index.html and others), I have just this:


The moment I run yarn start and visit one of the pages caught by [...path].tsx file, a HTML magically appears inside the folder.

For very specific project reasons, I need all the HTML to be pre-built and not incrementally generated like it's happening right now.

How can I achieve that?
