This tutorial demonstrates how to create a set of statically generated article list pages using Next.js and data from the Contentful GraphQL API. The application fetches data at build time, eliminating the need for client-side state, and uses Static Site Generation (SSG) to pre-render HTML pages. The blog post summaries are fetched from the Contentful API and displayed on the front end using a PostList component. The pagination is handled by a Pagination component that renders links to previous and next pages based on the current page number. The application can be built with webhooks in Contentful, which triggers a rebuild of the site every time a new change is published.
