Book Description

Welcome to the book "Angular Observables and Promises: A Practical Guide to Asynchronous Programming". In this book, I explain how to use observables and promises effectively for asynchronous programming. I show you practical scenarios and explain when you should use them and which operators you need to use. I will give you best practices with important pointers that, when used correctly, can make all the difference and have a big impact on performance. There are also things you should be aware of and avoid when working with observables, otherwise performance can be affected. By the end of this book, you will be able to use Observables and Promises in your Angular application and handle all kinds of scenarios. Let us get started.

Book Description

Upgrade your skillset, succeed at work, and above all, avoid the many headaches that come with modern front-end development. Simplify your codebase with hands-on examples pulled from real-life applications. Master the mysteries of asynchronous state management, detangle puzzling race conditions, and send spaceships soaring through the cosmos. When you finish this book, you'll be able to tame the wild codebeasts before they ever get a chance to wreck your day. The front-end world can be fraught with complexity. The RxJS library offers a solution: Observables. Observables merge other JavaScript asynch mechanisms such as callbacks and promises into a new way of looking at data. Instead of dealing with objects and keeping track of their state, Observables view asynchronous events as a stream. RxJS provides you the tools to manage, manipulate, and process Observables to simplify and speed up your front-end applications. Never fear, you're in exactly the right place. Don't worry about getting stuck in a mire of theory. Start off with the basics, building small applications that illustrate deeper points. Take those building blocks and apply them to much more complex problems like handling asynchronous state and dodging race conditions before they happen. Once you've got a handle on complex problems, take a leap into architecture, discovering how to structure an Observable-based application both without a framework and in the land of Angular 2. After mastering Observables, switch gears to building a canvas-based game, demonstrating your deep understanding of the flexibility of Observables. Master the Observable with RxJS, and make your asynchronous JavaScript code that much cleaner and simpler. What You Need: Any major browser and text editor, as well as the current versions of git, NodeJS, and npm.

Book Description

Summary RxJS in Action gives you the development skills you need to create reactive applications with RxJS. This book is full of theory and practical examples that build on each other and help you begin thinking in a reactive manner. Foreword by Ben Lesh, Project lead, RxJS 5. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology On the web, events and messages flow constantly between UI and server components. With RxJS, you can filter, merge, and transform these streams directly, opening the world of data flow programming to browser-based apps. This JavaScript implementation of the ReactiveX spec is perfect for on-the-fly tasks like autocomplete. Its asynchronous communication model makes concurrency much, much easier. About the Book RxJS in Action is your guide to building a reactive web UI using RxJS. You'll begin with an intro to stream-based programming as you explore the power of RxJS through practical examples. With the core concepts in hand, you'll tackle production techniques like error handling, unit testing, and interacting with frameworks like React and Redux. And because RxJS builds on ideas from the world of functional programming, you'll even pick up some key FP concepts along the way.
