How to use RxJS effectively in Angular for reactive programming
Introduction to Reactive Programming and RxJS Reactive programming is a paradigm that allows developers to build responsive, event-driven applications by modeling data as streams of events. In the context of Angular, RxJS (Reactive Extensions for JavaScript) is a powerful library that enables effective reactive programming. By embracing RxJS, developers can handle asynchronous operations, event streams,Continue reading “How to use RxJS effectively in Angular for reactive programming”
RxJS for Real Enterprise Use Cases: A Practical Course for Angular Developers
If you’ve worked on real Angular applications, you already know this truth: Most production problems are not about “how to use an operator”… They’re about handling complex async flows reliably. That’s exactly why I built my new course: RxJS for Real Enterprise Use Cases This course is designed for developers who want to move beyondContinue reading “RxJS for Real Enterprise Use Cases: A Practical Course for Angular Developers”
From 100KG (Kilograms) to a Healthier Me: My 25KG Weight Loss Journey
Over the past few months, people have started noticing the changes and often ask me, “What’s the secret?” Well, here it is! Almost 15 months ago, I was at 100KG (Kilograms), feeling sluggish and unhealthy. I knew I had to make a change, not just to look better but to feel better. Today, I’m 25KGContinue reading “From 100KG (Kilograms) to a Healthier Me: My 25KG Weight Loss Journey”
Using combineLatest in Angular to perform multiple HTTP requests but don’t wait until all done.
In a previous post we have seen how the forkJoin operator is used to group multiple http requests (basically group observables) and take action only when all the requests have returned, i.e, we are waiting until all the http calls are finished. But, what if we do not want to wait until all are done?,Continue reading “Using combineLatest in Angular to perform multiple HTTP requests but don’t wait until all done.”
Understanding the Basics of TypeScript: A Guide for JavaScript Developers
JavaScript has long been the language of the web, powering everything from simple animations to complex web applications. However, as applications grow in complexity, JavaScript’s dynamic nature can sometimes become a challenge. That’s where TypeScript comes in—a statically typed superset of JavaScript that offers improved tooling, better error checking, and scalable development. In this guide,Continue reading “Understanding the Basics of TypeScript: A Guide for JavaScript Developers”
Top JavaScript Libraries and Frameworks for Web Development in 2025
Web development continues to evolve rapidly, and JavaScript remains at the heart of building modern, responsive, and feature-rich applications. As we move into 2025, the JavaScript ecosystem offers more powerful tools than ever—ranging from libraries for UI components to full-stack frameworks for scalable applications. In this post, we explore the top JavaScript libraries and frameworksContinue reading “Top JavaScript Libraries and Frameworks for Web Development in 2025”
Create HTTP Observable from Fetch in Angular
Explore the fusion of Angular and the Fetch API to create HTTP observables. In this guide, we unveil the power of asynchronous HTTP requests, providing you with a deeper understanding of HTTP observables. The Fetch API offers granular control and flexibility, making it a compelling alternative to Angular’s built-in HttpClient module. Whether you’re a developer seeking versatility, fine-tuned requests, or a new perspective, this approach has you covered in web development.
Understanding RxJS Operators: concatMap, mergeMap, and exhaustMap
RxJS, or Reactive Extensions for JavaScript, is a powerful library for working with asynchronous data streams in JavaScript. It provides a wide range of operators that enable developers to manage and manipulate data flows effectively. Among these operators, concatMap, mergeMap, and exhaustMap are commonly used for transforming and managing observable sequences. In this blog post,Continue reading “Understanding RxJS Operators: concatMap, mergeMap, and exhaustMap”
Create a custom RxJS Operator – Debug Operator
Sometimes in reactive programming its difficult to understand logic or code when we are using multiple operators, it’s not always easy to read through the observable chain, so in order to better understand the program and to troubleshoot the code we often use the tap operator to log statements to the console. For example: Say,Continue reading “Create a custom RxJS Operator – Debug Operator”
