Static Reactions Demo

Reactions on this GitHub issue:

1. Each Next.js page can define the timeout. For this page, it’s set at 1 second.
2. When a new request comes in, the statically generated page is served.
3. Later, when another request comes in after the defined timeout is exceeded: (1) The statically generated page is served, and (2) Next.js generates a new version of the page in the background and updates the static page for *future* requests.
4. Later, when another request comes in after the regeneration is done: The updated static page is served.
5. This allows Incremental Static Regeneration on a per-page basis without rebuilding the full app. It’ll always be fast because users will always get a static response. Learn more here.
