A growing flood of data is aimed at JavaScript applications, and they need be ready for it. As more and more data is received, applications must scale to stay operational. There's also the problem of latency when data has to be fetched from remote locations. RxJS, or Reactive Extensions for JavaScript, is a library for transforming, composing, and consuming streams of data. RxJS combines reactive and functional programming to give an extensible, asynchronous event handling system for JavaScript. RxJS in Action gives readers the development skills they need to create reactive applications with RxJS. This book is full of theory and practical examples that build on each other and help readers begin thinking in a reactive manner. The book begins by teaching the fundamentals of functional programming, and dives in to the basics of RxJS and what it means to be reactive. Next, it teaches how to build real-world applications with RxJS. The last part of the book tackles the advanced topics to take the reader's reactive programming skills to the next level, as they will learn how to deal with error handling, unit testing, and the role of RxJS when combined with frameworks such as Angular.js or Cycle.js. Examples in the book use RxJS 5, the latest version of RxJS built with an eye on performance and simplicity. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

Manage state in Angular to write high performing web apps by combining the power of Flux, RxJS, and NgRx Key Features - Learn what makes an excellent Angular application architecture - Use Redux to write performant, consistent Angular applications - Incorporate Reactive Programming principles and RxJS to make it easier to develop, test, and debug your Angular applications Book Description Managing the state of large-scale web applications is a highly challenging task with the need to align different components, backends, and web workers harmoniously. When it comes to Angular, you can use NgRx, which combines the simplicity of Redux with the reactive programming power of RxJS to build your application architecture, making your code elegant and easy to reason about, debug, and test. In this book, we start by looking at the different ways of architecting Angular applications and some of the patterns that are involved in it. This will be followed by a discussion on one-way data flow, the Flux pattern, and the origin of Redux. The book introduces you to declarative programming or, more precisely, functional programming and talks about its advantages. We then move on to the reactive programming paradigm. Reactive programming is a concept heavily used in Angular and is at the core of NgRx. Later, we look at RxJS, as a library and master it. We thoroughly describe how Redux works and how to implement it from scratch. The two last chapters of the book cover everything NgRx has to offer in terms of core functionality and supporting libraries, including how to build a micro implementation of NgRx. This book will empower you to not only use Redux and NgRx to the fullest, but also feel confident in building your own version, should you need it. What you will learn Understand the one-way data flow and Flux pattern Work with functional programming and asynchronous data streams Figure out how RxJS can help us address the flaws in promises Set up different versions of cascading calls Explore advanced operators Get familiar with the Redux pattern and its principles Test and debug different features of your application Build your own lightweight app using Flux, Redux, and NgRx Who this book is for If you have been developing Angular applications and want to dive deeper into the Angular architecture with Redux, RxJS, and NgRx to write robust web apps, then this book is for you.

Reactive programming is revolutionary. It makes asynchronous programming clean, intuitive, and robust. Use RxJS 5 to write complex programs in a simple way, and master the Observable: a powerful data type that substitutes callbacks and promises. Think about your programs as streams of data that change and adapt to produce what you want. Manage real-world concurrency and write complex flows of events in your applications with ease. Take advantage of Schedulers to make asynchronous testing easier. The code in this new edition is completely updated for RxJS 5 and ES6. Create concurrent applications with ease using RxJS 5, a powerful event composition library. Real-world JavaScript applications require you to master asynchronous programming, and chances are that you'll spend more time coordinating asynchronous events than writing actual functionality. This book introduces concepts and tools that will greatly simplify the process of writing asynchronous programs. Find out about Observables, a unifying data type that simplifies concurrent code and eases the pain of callbacks. Learn how Schedulers change the concept of time itself, making asynchronous testing sane again. Find real-world examples for the browser and Node.js along the way: how about a real-time earthquake visualization in 20 lines of code, or a frantic shoot-'em-up space videogame? You'll also use Cycle.js - a modern, reactive, web framework - to make a new breed of web applications. By the end of the book, you'll know how to think in a reactive way, and to use RxJS 5 to build complex programs and create amazing reactive user interfaces. You'll also understand how to integrate it with your existing projects and use it with the frameworks you already know. All the code in this new edition has been thoroughly revised and updated for RxJS 5, ES6, and Cycle.js Unified. What You Need: NodeJS 6.x and a modern web browser

This book is a quick and useful guide to learning the reactive programming in Angular through step-by-step pictorial tutorials that are easily understood by beginners. It covers four important packages, including @NgRx/Store, @NgRx/Entity, @NgRx/Effects, and RxJS for developing large-scale reactive projects. Features in these four packages are covered thoroughly in this book with hands-on examples that allow readers to become experts in creating scalable and extendable web applications. What This Book Covers? Chapter 0, Getting Started with Angular NgRx, covers setting up an environment for developing Angular NgRx applications. If you are familiar with the development of the web application with Angular, please skip this chapter. Chapter 1, Reactive Programming in Angular for Beginners, develops a web application for beginners to Angular NgRx. We simplify the example in this chapter to focus on the basic and important concepts about the store and the relationship between a store and components and help beginners to grasp the main ideas in this chapter. Chapter 2, Communication between Two Components, evolves the concepts of the store, which shows how two components talk via a centralized store. Chapter 3, Nested Store Data Structure, manipulates the complicated data structure of states, introduces the concept of payload, and demonstrates how to select data from states with different levels. Chapter 4, Build Hierarchical Module, State, and Reducer, investigates how to build scalable and extendable projects with hierarchical modules, states, and reducers. It shows how @NgRx/Entity automatically generates code with functions of creating, retrieving, updating, and deleting data (CRUD). Chapter 5, Retrieve the Store with Selectors, continues to discuss how to retrieve data based on @NgRx/Entity and how to mimic the functions of SQL SELECT with selectors. Chapter 6, Introduction to RxJS, walks you through creating, filtering, transforming, and manipulating observables which are streams of data. RxJS is an important tool to create reactive applications and help you understand the next chapters. Chapter 7, Injectable Action Listener, Processor, and Dispatcher, explores @NgRx/Effects which listen to actions and perform the function of logging. Chapter 8, Handling HTTP Requests with Effects, demonstrates the interactions among servers, services, effects, stores, and components through a stock view web application.
