Category: Authentication and Authorization

Authentication and authorization are critical components of modern web applications. Authentication ensures that a user is who they claim to be, while authorization determines what resources the user can access. Proper implementation ensures application security, protects sensitive data, and enhances user trust. In Angular, these processes are typically implemented using JWT (JSON Web Tokens), route…

In modern Angular applications, authentication tokens such as JWTs (JSON Web Tokens) are essential for securing API calls. HTTP interceptors provide a centralized way to attach these tokens to all outgoing requests automatically, ensuring consistent authentication and reducing repetitive code in services and components. This post provides a comprehensive guide to setting up JWT HTTP…

While frontend security in Angular is essential for user experience and navigation control, it is not sufficient to fully protect an application. A determined attacker can bypass the frontend, manipulate requests, or directly call backend endpoints. Therefore, securing backend APIs is critical to prevent unauthorized access, data breaches, and manipulation. This post explores how to…

1. Introduction Angular provides a powerful Router module for navigating between views in a single-page application. However, in modern applications, not all routes should be accessible to every user. Some routes may be restricted to: Angular solves this problem using route guards, specifically the CanActivate guard. CanActivate allows developers to control access to routes by…

Role-Based Access Control (RBAC) is a fundamental security practice in Angular applications. It determines what a user can or cannot access based on their assigned role. RBAC improves security, simplifies authorization logic, and ensures that sensitive functionality is only accessible to authorized users. This post explains how to implement RBAC in Angular using services, guards,…

Authentication is one of the most essential aspects of modern web applications. In Angular, the most common way to authenticate users securely is through JSON Web Tokens (JWTs). JWT-based authentication provides a stateless and scalable way to handle user sessions between a frontend and backend API. This post explains how to store JWT securely, attach…

Authentication is a critical part of any modern web application. In Angular, services provide a centralized and reusable way to handle authentication logic such as logging in users, storing tokens, and managing session state. A well-structured login service improves code maintainability, security, and scalability. This post will provide a comprehensive guide to setting up a…

JWT (JSON Web Token) authentication is a widely used method to secure client-server communication in modern web applications. It allows users to authenticate once and securely transmit information with each subsequent request. JWTs are compact, URL-safe tokens that can be easily used in HTTP headers and efficiently verified by the backend. In this post, we…

1. Introduction In modern web applications, managing who can access your app and what they can do is crucial. This involves two fundamental concepts: In Angular applications, authentication often relies on JWT (JSON Web Tokens), while authorization is implemented using role-based access control (RBAC). Proper implementation of these mechanisms ensures that both frontend routes and…
