Reading Time: 5 minutes In Java, we are often tempted towards writing a code which is executed eagerly. There’s a good reason for that – eager code is easy to write and to reason about. But delaying commitments until the last responsible moment is a good agile practice. When executing the code, we can gain performance by being just a little lazy. In this blog, we will try to Continue Reading
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: 4 minutes In the previous blog, we discussed the journey and the features of RAP. In this blog, we will discuss the architecture and technical details. RAP Architecture: We have tried to follow the Domain-Driven Design and Reactive principles in designing RAP architecture. All RAP team members completed all the Reactive Architecture courses launched by Lightbend on cognitive classes to ensure adherence to reactive principles. These courses Continue Reading
Reading Time: 5 minutes In the world of cloud computing, big data and IoT, system and application requirements have changed by leaps and bounds in recent years. Even the challenges being faced by developers and enterprises today are way different from the ones that they faced, say, a decade or two earlier. Find out why should modern enterprises opt for reactive systems today?
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: 5 minutes We can use spring-boot:webflux’s WebClient to invoke a third-party service from within our spring boot application. This is asynchronous and reactive method supplied by spring for invoking of unmanaged services. We also saw how we can pass query params when invoking a 3rd party service and which case to chose with our requirements. Be cautious with what you are using and always document what you want and what you created so that things like these can be caught early during the development phase.
Reading Time: 4 minutes A few months back, I was working on interesting customer engagement. Lagom was getting popularity, therefore, I and my few team members wanted to explore it to see if it would suit our needs. Just reading its documentation was not enough to get the proper practical hands-on. So we thought to do a project. The idea was that we should not build a dummy project, 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: 2 minutes In the REST APIs, all Http requests are stateless. We fire the request and get the response, That’s it. It does not keep any state for any HTTP request. The connection between client and server is lost once the transaction ends, so 1 response for 1 request. But sometimes, we get the requirement to have a continuous response for a single request. This continuous response Continue Reading
Reading Time: 2 minutes This post briefs you about the integration of Springboot with Mysql using JPA
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 As I am exploring Spring Web flux these days so I got an opportunity to explore the different ways of interacting with couch base using reactive APIs. We will not discuss how we can make a crud application in Spring Web flux. My main focus will be on, in how many different ways, we can query the couchbase with reactive couchbase API in Spring Web Continue Reading
