Learning C++ is one of the most valuable steps you can take as a programmer. Whether you are a beginner exploring coding for the first time or a developer expanding your skills, C++ provides a strong foundation for understanding how software interacts with hardware and memory. Before you can begin writing and executing C++ programs,…

C++ is one of the most powerful and widely used programming languages in the world. It combines the efficiency and control of low-level programming with the flexibility and abstraction of high-level programming. Whether you want to create system software, game engines, applications, or embedded systems, C++ gives you the tools to do so. If you…

C++ is one of the most powerful and widely used programming languages in the world. It has been around for decades, shaping the foundation of modern software development. From operating systems to video games, from embedded systems to large-scale enterprise applications, C++ has proven its strength, speed, and flexibility. In this detailed introduction, you will…

This C++ tutorial has been written by experienced C++ programmers, which helps beginners to advanced programmers while learning C++ in simple and easy steps. This tutorial uses a simple and practical approach to describe the concepts of C++to software engineers. What is C++? C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at…

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…
