Update static page

[MohammadPCh]

Hi,
I'm developing a site about movies, an example URL is:
https://example.com/movie/[id]/[name]
for exmaple:
https://example.com/movie/1/blabla
I build each page in run time with set fallback: true, and the site has about 200K movie page. Some times the content of one page needs to update. for example, I build 200,000 static pages, and one movie with id 60 was changed! I don't want to build all pages again, I just want to update a page.
I found that I can remove files of that page from build folder: (blabla.json & blabla.html) but it seems NextJS cached it in its memory and it serves the old files without building new files.
I know NextJs introduce revalidate for updating, but it is useless for this scenario because I don't want update page continuously. I just want to update a page sometimes.

In my opinion, it's nice to have an API for purge a static page, so the user doesn't need to build 200,000 pages to update one page.

Does anybody have an idea?

@MohammadPCh Did you find a solution? This is something I was wondering about as well

Did you try to return your initialProps from getStaticProps with the revalidate flag ?

Like so :

    initialProps = await api.get();
    return { props: { ...initialProps }, revalidate: 1 };

But that would mean it would regenerate every second if we have a site with very high traffic right?

I guess there needs to be some functionality to actively trigger a regeneration of a specific static page.
Let's say we have a product page where the data changes every few days but whenever it changes the page should be updated soon.

• revalidate of 1 would mean lot's of regenerations which are not necessary
• a high revalidate value would mean a potentially outdated page

I post a feature request here: #16488.
I suggest a solution, please watch it and let's talk there.
