Reactive Programming: Spring WebFlux

March 7, 2023April 2, 2023Java, Reactive ProgrammingSpring Webflux

Reading Time: 3 minutes Reactive Programming Reactive has specific characteristics that make them ideal for low-latency, high-throughput workloads. Project Reactor and the springWebflux work together to enable developers to build enterprise-grade reactive systems that are responsive, resilient, elastic, and message-driven. What is reactive processing? Reactive processing is a paradigm that enables developers to build non-blocking and asynchronous applications which can handle back-pressure (flow control). Why use reactive processing? Reactive Continue Reading

How to start with Spring web-flux

Reading Time: 4 minutes Spring Boot provides very good support for building RESTful Web Services for enterprise applications. This blog will explain building RESTful web services using Spring Boot in detail with a pinch of reactive programming using web flux. I will mostly be walking through the code snippets which we can use to quickly start with the web flux without having to dive deep. It is like a Continue Reading

Router Function in Spring Webflux

September 30, 2022October 19, 2022Java, java11, Tech Blogsjava, Spring, Spring Webflux

Reading Time: 3 minutes Overview In Spring WebFlux, router functions are used to route requests to the corresponding HandlerFunction. Typically, you don’t write router functions yourself, but use a method in the RouterFunctions handler class to create them. RouterFunctions.route() (with no parameters) gives you a fluent constructor to create a router function, while RouterFunctions.route(RequestPredicate, HandlerFunction) gives you a direct way to create a router. It is generally recommended to Continue Reading

Protocols and Backpressure in Spring WebFlux

September 26, 2022October 25, 2022Studio-Scalajava, Reactive Programming, Spring Webflux, websockets

Reading Time: 3 minutes The WebSocket Protocol Never blocking is one of the main suggestions for dealing with data streams. A client using data from a stream should never block the thread because it does not own it. Putting them in a buffer will stop them from being released. However, buffers have a finite capacity, can overflow, and can lose data. The client should be able to regulate how Continue Reading

Logging in Spring WebFlux

August 30, 2022September 13, 2022Java, java11, Spring, Spring WebFlux, Tech Blogsjava, Logging, Spring, Spring Webflux

Reading Time: 2 minutes Overview: DEBUG level logging in Spring WebFlux is compact, minimal, and human-friendly. Itfocuses on high-value bits of information that are useful over and over again vs others that areapplicable only when debugging a specific issue. TRACE level logging generally follows the same principles as DEBUG (and for example also should notbe a firehose) but can be used for debugging any issue. In addition, some log Continue Reading

A Basic Introduction To Spring WebFlux

August 30, 2022September 13, 2022Java, Spring WebFluxSpring Webflux

Reading Time: 3 minutes Introduction Spring WebFlux, like SpringMVC, provides reactive, async, non-blocking programming support for web applications in an annotated Controller style. This method is comparable to how Node.js works. Javascript employs an async, non-blocking approach, which contributes to its scalability. It uses a similar architecture, but with several event loops. Spring WebFlux, a different approach to creating web apps built on reactive programming.. Reactive apps using WebFlux Continue Reading

Reading Time: 3 minutes Spring 5 is the first Spring framework that offers built-in support for reactive programming. This blog is an introduction to Spring WebFlux’s . Spring frameworks that have built-in support for reactive programming. so first we will understand what is reactive programming. Reactive programming It is a programming paradigm that used an asynchronous, non-blocking, event-driven approach to data processing. Reactive programming added modeling data and events Continue Reading

July 27, 2022August 2, 2022Spring WebFluxSpring Webflux

Reading Time: 3 minutes Introduction Spring 5 includes Spring WebFlux, which provides reactive programming support for web applications. In this blog, we’ll create a small reactive REST application using the reactive web components RestController and WebClient. We’ll also look at how to secure our reactive endpoints using Spring Security. Spring WebFlux Framework Spring WebFlux internally uses Project Reactor and its publisher implementations, Flux and Mono. The new framework supports two programming models: Annotation-based Continue Reading

Getting started with Spring Webflux

Reading Time: 3 minutes Overview Hello everyone, In this blog, I am going to discuss an introduction to webflux. The original web framework included in the Spring Framework, Spring Web MVC, was purpose-built for the Servlet API and Servlet containers. The reactive-stack web framework, SpringWebFlux was added later in version 5.0. What is Spring Webflux? Spring Webflux is fully non-blocking and supports Reactive Streams back pressure. It runs on Continue Reading

Spring-Webflux: How to test controllers?

July 19, 2022July 22, 2022Spring WebFluxcontrollers, Spring Webflux

Reading Time: 3 minutes Introduction : While working with Spring MVC, you might have used Spring MockMVC to perform testing of Spring web MVC controllers. MockMVC class is part of the Spring MVC test framework which helps in testing the controllers explicitly starting a Servlet container. But, this is not something that will work if you are using SpringBoot Webflux. If you have a Spring application built with Webflux, the MVC controllers can be tested Continue Reading

Salient Features of Spring WebFlux

Reading Time: 4 minutes What is Spring WebFlux? Spring WebFlux is a fully non-blocking, annotation-based web framework built on Project Reactor that makes it possible to build reactive applications on the HTTP layer. WebFlux uses a new router functions feature to apply functional programming to the web layer and bypass declarative controllers and RequestMappings. It requires you to import Reactor as a core dependency. WebFlux was added in Spring 5 as a reactive Continue Reading
