This tutorial teaches users how to build a full-stack application using Strapi and Next.js, two popular technologies in the developer community. The process begins by setting up a new Strapi project and creating content types for recipes and categories. It then guides users through setting up their Next.js frontend, connecting it to the Strapi backend, and building a recipe book with dynamic routes and pages. The tutorial also covers how to use Strapi's built-in REST API and Next.js's server-side rendering capabilities. Throughout the process, users learn about best practices for managing data and permissions in their application. Ultimately, this tutorial aims to empower developers to build complex applications using these technologies and explore the possibilities of a headless CMS.
