Whenever you change the back-end content and are eager to view in front-end, we have implemented “Preview Feature” feature of ReactJS/NextJS framework.
Take a look at documentation https://nextjs.org/docs/advanced-features/preview-mode
To swtich to preview mode simpy call
/api/preview?slug=<slugname>` from Frontend.
Inbuilt, We have configured Nextjs preview feature with link e.g., /api/preview/. So that whole your site is in preview mode by default.
