Implementing Authentication and Authorization in Vue

Vue, a web framework for building scalable user interfaces, can be enhanced with authentication and authorization features to manage user access effectively. This guide details the implementation of authentication in a Vue application using Firebase, which simplifies user authentication through multiple sign-in methods and integrates seamlessly with Vue. Additionally, it explores authorization models such as Attribute-Based Access Control (ABAC) and Relationship-Based Access Control (ReBAC) using Permit.io, which allows for fine-grained access control based on user attributes and relationships, respectively. A demo food delivery application is used to illustrate these concepts, showcasing how ABAC can enforce policies based on order cost and ride history, while ReBAC ensures that vendors can only fulfill their own orders. The integration of these models helps create a secure, flexible authorization system that can scale with the application, offering a robust solution for managing user permissions and enhancing application security.
