As it is build on top of Akka Actors, it provide Continue Reading
Reading Time: 3 minutes Overview RxJava is a JVM implementation of Reactive Extensions and a reactive programming implementation based on event driven and asynchronous programs. It works on the principles of observables and observer patterns. RxJava is lightweight and implemented as a single JAR on the observable abstraction and related higher-order functions. (For those who are new to Reactive Programming and have less familiarity with it. Reactive programming is Continue Reading

Reading Time: 4 minutes What Happens When Reactive Meets Microservices? It would be beneficial if you understand the concepts of Reactive Architecture before diving into Reactive Microservices. You can read about Reactive Architecture here: Leaning Towards Reactive Architecture In this article we will cover transition from Monoliths to Service Oriented Architecture to Reactive Microservices by applying isolation techniques to the application. What are Monoliths? To start explaining the microservices Continue Reading
Reading Time: 4 minutes Reactive programming has been a good to go approach with the microservices architecture. Here we will see how it can be achieved using spring web flux MONO Api and what could go wrong if we do not consider the basics of the reactive environment.
Reading Time: 2 minutes Recently I got an invitation to present a guest lecture for faculty of Engineering colleges in ABES college of Engineering. I came up with the most trending topic i.e Reactive Architecture. We talked about what is this buzzing keywords and why does it came into existence. Also What are the challenges one were facing and how are the real world problems being solved by using Continue Reading
Reading Time: 4 minutes Whenever we have tried to learn about functional programming, these two terms have always gained our attention. The first one is pure functions and the second one is immutability. I have tried to explain what are pure functions in one of my previous blogs. In this particular blog, we’ll discuss the practicality of programming with immutability. What does immutability mean? The definition that you can Continue Reading
Reading Time: 3 minutes With a lot of buzz in the programming world about “reactive Programming”, a new concept following the same path has been introduced. This is “Reactive streams” backed up by the idea of backpressure. In this blog, we try to understand, what does it mean exactly? What are Reactive Streams? We are here talking about handling streams of data that needs to be handled in an Continue Reading
Reading Time: 3 minutes Functional programming is a programming paradigm which is gaining its popularity day by day. It revolves around binding everything in pure mathematical functions style. It is is the process of building software by composing pure functions, avoiding shared state, mutable data, and side-effects. Functional programming is declarative rather than imperative, and application state flows through pure functions. We call it as a declarative type of Continue Reading
Reading Time: 3 minutes This post talks about the Spring5’s WebClient feature to make calls to external APIs. Also, how unit test case are written for SpringBoot Webclient.
Reading Time: 3 minutes With the world moving towards the reactive and functional ways of programming, Spring also turned its steps on the same path. This leads to the origin of Spring Webflux. To understand the functional approach towards it, we first need to understand, what is Spring Webflux exactly? Before Spring version 5.0, the original web framework included in the Spring Framework, Spring Web MVC, was built for Continue Reading
Reading Time: 5 minutes In this blog post we’ll see how a file can be streamed from a client (eg: browser) to Amazon S3 (AWS S3) using Alpakka’s AWS S3 connector. Aplakka provides various Akka Stream connectors, integration patterns and data transformations for integration use cases. The example in this blog post uses Play Framework to provide a user interface to submit a file from a web page directly to Continue Reading
