The comprehensive tutorial explores the integration of Strapi, an open-source, headless Content Management System (CMS), with a React application to implement authentication and authorization. By employing Strapi's flexible authentication system, developers can leverage both social and local authentication methods, returning a JWT token for secure requests. Strapi’s Roles & Permissions plugin ensures robust API protection through an Access Control List (ACL) strategy, verifying user access with each request. The tutorial guides users in building a React application that features user registration, login, and profile editing, utilizing components such as React Context and hooks for efficient state management. The article also showcases the creation of a social card application, detailing backend setup with Strapi and frontend development with React, including routing, UI components, and API integration. The tutorial culminates in a fully functional application, demonstrating how developers can apply these practices to enhance their projects with a secure and scalable architecture.
