Summary : Learn the hot new front-end web framework from Facebook: ReactJS, an easy way of developing the V in MVC and a better approach to software engineering in JavaScriptAbout This Book• Learn to develop webapps for Facebook's front-end development using ReactJS• Use functional reactive programming with ReactJS• Easyto understand, comprehensive with in-depth coverage of practical examplesWho This Book Is ForIf you are proficient with JavaScript and want to know about functional programming, reactive programming, functional reactive programming, and the Facebook approach to functional reactive programming then this book is for you.This book is also for web/front-end developers who would like webapps to be developed faster and more easily using the ReactJS framework.Basic knowledge of JavaScript is expected.What You Will Learn• Learn functional reactive programming with JavaScript for non-mathematicians• Experience Facebook's primary front-end framework, ReactJS• Using the tools Facebook uses to build a better site in less time• Create and implement Node.js• Delve into the development of webapps using ReactJS• Implementation of FRP ReactJS with live examplesIn DetailReactive programming is carried out using the building blocks of functional programming. JavaScript libraries such as ReactJS are used for front-end web development that is both competent and powerful. ReactJS is intensively being used to develop webapps for Facebook.This title is among the first of those addressing how everyday programmers can take advantage of (functional) reactive programming without having an extremely heavy mathematical background. It starts with the basics a front-end developer can easily connect with, while also covering the basics of functional programming. Then it goes on to explain non-functional reactive programming with the help of a live example. After that it gives a theoretical overview of reactive programming supported by functional programming. Tools to make functional reactive programming easier like Bacon.js, a library like jQuery, are also covered. Finally, it finishes with building one small and one larger front-end project.Style and approachA rounded and multifaceted approach covers reactive JavaScript with Facebook's ReactJS. The author's lively approach makes the book even more engaging. Also, with easy-to-understand examples, readers will learn how to use functional reactive programming with JavaScript.

Summary : Learn how to institute Reactive Programming (RP) for your back-end development with Node.js. Up to now, RP has most often been used in front-end development, but with its cutting-edge approach you can also transform your back-end programming. Reactive Programming with Node.js will show you the paradigms of RP, why you should use it, and the variations available to you. You will learn how to use the main libraries necessary to provide an enhanced development experience in Node.js, including RxJS, Bacon.js, Kefir.js, and Highland.js. You will also create a custom library that provides a variety of key features, and learn how to scale up a system developed using RP in Node.js. Ideal for back-end developers with knowledge of Node.js or JavaScript, this book enables you to get up and running with RP in Node.js, and revolutionize your back-end development. What You'll Learn: Review the variations of Reactive programming Use the main libraries that provide this type of development experience in Node.js Create a custom library Scale up a system developed using RP in Node.js Who This Book Is For: Any back-end developers who understand Node.js or are advanced enough to pick up the basics. Ideal for developers who have an interest in learning about this different programming paradigm that's being used more and more every day.

Summary : Expand your boundaries by creating applications empowered with real-time data using RxJs without compromising performance Key Features [*] Handle an infinite stream of incoming data using RxJs without going crazy [*] Explore important RxJs operators that can help you improve your code readability [*] Get acquainted with the different techniques and operators used to handle data traffic, which occurs when you receive data faster than you can process Book DescriptionIf you’re struggling to handle a large amount of data and don’t know how to improve your code readability, then reactive programming is the right solution for you. It lets you describe how your code behaves when changes happen and makes it easier to deal with real-time data. This book will teach you what reactive programming is, and how you can use it to write better applications. The book starts with the basics of reactive programming, what Reactive Extensions is, and how can you use it in JavaScript along with some reactive code using Bacon. Next, you’ll discover what an Observable and an Observer are and when to use them.You'll also find out how you can query data through operators, and how to use schedulers to react to changes. Moving on, you’ll explore the RxJs API, be introduced to the problem of data traffic (backpressure), and see how you can mitigate it. You’ll also learn about other important operators that can help improve your code readability, and you’ll see how to use transducers to compose operators. At the end of the book, you’ll get hands-on experience of using RxJs, and will create a real-time web chat using RxJs on the client and server, providing you with the complete package to master RxJs. What you will learn [*] Get to know the basics of functional reactive programming using RxJs [*] Process a continuous flow of data with linear memory consumption [*] Filter, group, and react to changes in your system [*] Discover how to deal with data traffic [*] Compose operators to create new operators and use them in multiple observables to avoid code repetition [*] Explore transducers and see how they can improve your code readability [*] Detect and recover from errors in observables using Retry and Catch operators [*] Create your own reactive application: a real-time webchat Who this book is for If you're a web developer with some basic JavaScript programming knowledge who wants to implement the reactive programming paradigm with JavaScript, then this book is for you.

Summary : Take advantage of JavaScript’s power to build robust web-scale or enterprise applications that are easy to extend and maintain. By applying the design patterns outlined in this practical book, experienced JavaScript developers will learn how to write flexible and resilient code that’s easier—yes, easier—to work with as your code base grows. JavaScript may be the most essential web programming language, but in the real world, JavaScript applications often break when you make changes. With this book, author Eric Elliott shows you how to add client- and server-side features to a large JavaScript application without negatively affecting the rest of your code. Examine the anatomy of a large-scale JavaScript application Build modern web apps with the capabilities of desktop applications Learn best practices for code organization, modularity, and reuse Separate your application into different layers of responsibility Build efficient, self-describing hypermedia APIs with Node.js Test, integrate, and deploy software updates in rapid cycles Control resource access with user authentication and authorization Expand your application’s reach through internationalization
