There is an ongoing shift in content management from traditional CMS to headless CMS. A headless CMS allows you to completely separate your content management system from the presentation layer. The content is made available via API and can be consumed in any kind of frontend, from websites to mobile apps.

Using headless CMSs has opened up a new way of building websites, known as pre-rendering. It is one of the best-known techniques in Jamstack, in which the website is compiled into a set of static assets like prebuilt HTML, CSS, and JavaScript files with the help of a static site generator (SSG). During the build time, the files are created by collecting the data from a headless CMS. These files are cached to a content delivery network (CDN) and served to a user on each request from the nearest CDN node. This improves speed and response times and reduces hosting costs.

However, content creators need to preview their content before publishing it to production, meaning they need to wait for an entire build to complete before they can view their content. To solve this problem, a preview mode allows editors to view their changes on the fly.

In this tutorial, you’ll learn to implement a preview system when working with a headless CMS like Strapi. You’ll implement the frontend in Next.js for creating content previews.
