Download or read book Reactive Internet Programming written by Franck Barbier and published by Morgan & Claypool. This book was released on 2016-04-01 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is Internet software so different from “ordinary” software? This book practically answers this question through the presentation of a software design method based on the State Chart XML W3C standard along with Java. Web enterprise, Internet-of-Things, and Android applications, in particular, are seamlessly specified and implemented from “executable models.” Internet software puts forward the idea of event-driven or reactive programming, as pointed out in Bonér et al.’s “Reactive Manifesto” (http://www.reactivemanifesto.org). It tells us that reactiveness is a must. However, beyond concepts, software engineers require effective means with which to put reactive programming into practice. This book’s purpose is to outline and explain such means. The lack of professional examples in the literature that illustrate how reactive software should be shaped can be quite frustrating. Therefore, this book helps to fill in that gap by providing in-depth professional case studies that contain comprehensive details and meaningful alternatives. Furthermore, these case studies can be downloaded for further investigation. Internet software requires higher adaptation, at run time in particular. After reading Reactive Internet Programming, the reader therefore will be ready to enter the forthcoming Internet era.

Download or read book Reactive Programming with RxJS written by Sergi Mansilla and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive programming is revolutionary. It makes asynchronous programming cleaner, intuitive, and robust. Discover how to use the RxJS library to write programs in a simpler way, unifying asynchronous mechanisms such as callbacks and promises into a single, powerful construct. Learn to think about your programs as streams of data that you can transform by expressing what should happen, instead of having to painstakingly program how it should happen. You'll be able to handle real-world concurrency and write complex flows of events in your applications with ease. Create highly concurrent applications while writing simpler code using the Reactive Extensions for JavaScript (RxJS), a set of libraries for event composition. Programming real-world applications in JavaScript involves lots of asynchronous events--you might end up spending more time coordinating asynchronous code in your program than writing its actual functionality. This book introduces concepts and tools from reactive programming that will help you write cleaner and more robust asynchronous programs. Find out about Observable sequences, a unifying data type to write highly concurrent code. Discover Schedulers and change the concept of time in your applications, making asynchronous testing sane again. Along the way you'll see real-world examples for the browser and Node.js, including a real-time earthquake visualization in 20 lines of code and a frantic shoot-'em-up space videogame. You'll also use Cycle.js - a modern, fully reactive web framework - to make a whole new breed of web applications. By the end of the book, you'll know how to apply reactive programming to solve complex problems, build efficient programs with reactive user interfaces, and write your code more declaratively. What You Need: A modern web browser, Node.JS installed in your computer, and the RxJS JavaScript library.

Download or read book Reactive Spring written by Josh Long and published by . This book was released on 2020-09-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Microservices and big-data increasingly confront us with the limitations of traditional input/output. In traditional IO, work that is IO-bound dominates threads. This wouldn't be such a big deal if we could add more threads cheaply, but threads are expensive on the JVM, and most other platforms. Even if threads were cheap and infinitely scalable, we'd still be confronted with the faulty nature of networks. Things break, and they often do so in subtle, but non-exceptional ways. Traditional approaches to integration bury the faulty nature of networks behind overly simplifying abstractions. We need something better.Join Spring Developer Advocate Josh Long for an introduction to reactive programming in the Spring ecosystem, leveraging the reactive streams specification, Reactor, Spring Boot, Spring Cloud and so much more.This book will cover important concepts in reactive programming including project Reactor and the reactive streams specification, data access, web programming, RPC with protocols like RSocket, testing, and integration and composition, and more.
