Lazy loading is a design pattern in Angular that allows modules to be loaded on demand rather than at the application startup. This approach reduces the initial bundle size, improves application performance, and optimizes resource usage for large applications. In this post, we will go through step-by-step instructions for setting up lazy loading in Angular,…

Lazy loading is one of the most powerful performance optimization techniques in Angular. It allows developers to load feature modules only when they are needed, instead of loading all modules at the initial application startup. This results in smaller bundle sizes, faster loading times, and improved overall performance — especially in large-scale applications. In this…

1. Introduction Routing is one of the most powerful features of Angular. It allows developers to create single-page applications that can navigate between different views without reloading the page. The Angular Router is responsible for interpreting browser URLs and displaying the corresponding view to the user. While basic routing is enough for small applications, as…

State management is one of the most important aspects of building scalable, predictable, and maintainable Angular applications.Every Angular app maintains state — data that determines what the user sees and how the app behaves. Managing that state correctly ensures consistent behavior, easier debugging, and better performance. This comprehensive guide explores best practices for state management…

State management in Angular applications becomes significantly more efficient and predictable with NgRx. However, behind the power of NgRx lies the reactive foundation built using RxJS. NgRx leverages Observables, Subjects, and various RxJS operators to handle state transitions, side effects, and asynchronous data streams. This post explores the deep connection between RxJS and NgRx, explaining…

Introduction State management is a critical aspect of building large and scalable Angular applications. As applications grow, managing and synchronizing state across multiple components becomes challenging.This is where NgRx Store — a reactive state management library built on top of RxJS — provides a robust solution. The NgRx Store follows the principles of Redux, using…

Overview of NgRx NgRx is a powerful state management library for Angular applications inspired by the Redux pattern. It enables developers to manage complex application states in a predictable, reactive, and centralized way. At its core, NgRx uses Actions, Reducers, Selectors, and Effects to handle application logic and data flow. It leverages RxJS Observables to…

Introduction State management is one of the most crucial aspects of building robust and maintainable Angular applications. At the component level, managing state efficiently ensures that data changes are tracked, reflected in the UI, and shared across components when necessary. Angular provides several ways to manage state, such as: However, as the application grows, these…

Reactive programming is one of the most powerful and modern paradigms used in software development today. In Angular, it forms the foundation of how data flows between components, services, and asynchronous sources such as HTTP requests, user events, or WebSockets.Instead of pulling data manually, reactive programming lets you react automatically whenever data changes. This 3000-word…

Reactive programming is one of the most powerful paradigms in modern frontend development, and Angular makes it possible through RxJS (Reactive Extensions for JavaScript).Among the many classes provided by RxJS, the BehaviorSubject stands out as one of the most commonly used and essential tools for maintaining and broadcasting state across your Angular application. This comprehensive…
