This tutorial helps developers build a deliveroo clone using Next.js, GraphQL, Strapi, and Stripe. The tutorial starts with creating a new Strapi project and defining the restaurant content type. It then guides users through adding restaurants to the database and exposing them as an API. The tutorial also covers integrating GraphQL with Strapi's built-in API and implementing Apollo client in the frontend application. Finally, it shows how to display the list of restaurants on the page using a search bar for filtering. Throughout the tutorial, users can learn about building REST endpoints, GraphQL queries, and integrating APIs with frontend applications.
