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…

Advanced routing in Angular allows you to build secure, performant, and scalable applications. While basic routing covers navigation between components, advanced routing introduces concepts like lazy loading, route guards, preloading strategies, and modular route organization. This post outlines best practices to follow when designing routing for complex Angular applications, along with detailed examples and code.…

Preloading modules in Angular allows applications to load lazy-loaded modules before they are needed, improving perceived performance and user experience.By default, Angular provides two strategies for preloading modules: However, in complex applications, developers often need fine-grained control over which modules to preload.Angular allows this using a custom preloading strategy. This guide provides a detailed explanation…

Preloading strategies in Angular are closely tied to lazy-loaded modules. While lazy loading optimizes initial load time by loading modules only when needed, preloading takes it a step further by loading modules in the background after the initial app load. This ensures faster navigation to routes without compromising the initial load performance. This post explores…

Introduction to CanDeactivate Guard In Angular, guards are special services that control access to routes. They can prevent unauthorized access, redirect users, or confirm navigation actions. Among these, the CanDeactivate guard is particularly useful for preventing users from leaving a route when they have unsaved changes or incomplete actions. The CanDeactivate guard allows developers to…

1. Introduction to Route Guards In modern Angular applications, routing is not just about navigating between views. It’s also about controlling access to certain areas of your application based on conditions like user authentication, role-based access, or unsaved changes. Angular provides route guards as a built-in mechanism to control navigation. They allow developers to determine…

Building secure and reliable web applications often requires controlling which users can access specific routes or components.In Angular, this is achieved using Route Guards — special classes that decide whether navigation to a route should be allowed or prevented. This comprehensive post explores every aspect of Angular Route Guards — their purpose, types, implementation, and…

Lazy loading is one of the most powerful optimization techniques available in Angular applications. It allows developers to load feature modules only when they are needed instead of loading the entire application bundle at once. This significantly improves performance, reduces initial loading time, and enhances the user experience — especially in large, enterprise-level applications. This…
