What is ISR?
Incremental Static Regeneration. Pages are built once and served as static files, then quietly rebuilt in the background on a schedule so content stays reasonably fresh.
served static · rebuilt after 60 s
ISR regenerates pages...
Write it in your own words in the app.
In real work
Set up ISR for the product pages. Revalidate every 60 seconds. Fast static responses, reasonably fresh data.
In the illustration
Visitors take printed pages from the rack instantly; the timer has run past 60 s, so the next visitor still gets the old page instantly but trips the reprinter, which prints a fresh page behind the rack and swaps it into the slot.
Switch the blog index to ISR on your deploy platform. Revalidate every 60 seconds and on publish, so new posts go live without a full rebuild.
