This tutorial provides a comprehensive guide on developing a full-stack online food ordering application using a tech stack that includes Next.js, GraphQL, Stripe, and Strapi. It involves setting up both the front-end and back-end components, where Next.js is used for server-rendered applications with Tailwind for styling, and Strapi serves as the Headless CMS for the backend, utilizing PostgreSQL for database management. The tutorial walks through creating a project directory, configuring environment variables, and establishing a Strapi API to handle user authentication, restaurant, and menu management, along with Stripe for payment integration. The guide highlights the installation and configuration processes for each technology, ensuring a seamless development experience, and provides access to the source code on GitHub, serving as a valuable resource for developers looking to build scalable and secure web applications.
