Description

RxJS is a powerful reactive extension for JavaScript, specializing in asynchronous and event-driven programming, but you don’t find many books on using RxJS in Angular applications. Written by an industry expert with over a decade of experience, this book helps you navigate reactive patterns, efficient data management, and the streamlined implementation of common features with minimal code. This second edition aligns with the latest version of Angular, introducing new reactive patterns based on Angular Signals, which play a pivotal role in enabling fine-grained reactivity within Angular and enhancing change detection and user interface rendering. Throughout the book, you’ll construct a complete application that incorporates the latest Angular features, such as standalone components, new built-in control flow, deferrable views, and more. You’ll also focus on cultivating skills to handle data reactively, thus improving the application's overall quality, user experience, and developer productivity. The book covers best practices for testing asynchronous streams and optimizing app performance. By the end of this RxJS and Angular book, you’ll not only be able to develop Angular applications by implementing reactive patterns, but also grasp all the best practices, ensuring a well-rounded understanding of RxJS within the Angular framework.

Who is this book for?

If you're a developer working with Angular and RxJS, this book is for you. Designed for anyone at a beginner level in both Angular and RxJS, this book will help you gain experience and harness the potential of RxJS or benefit you if you’re looking to leverage the reactive paradigm within your Angular applications. This book assumes some familiarity with Angular, basic RxJS, and TypeScript, as well as foundational knowledge of functional programming.

What happens if an Early Access Course is cancelled?

Projects are rarely cancelled, but sometimes it's unavoidable. If an Early Access course is cancelled or excessively delayed, you can exchange your purchase for another course. For further details, please contact us here.

Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published.

Like many people in their continuing learning journey with Angular, appreciation of reactivity comes with time. I was thrown off the deep end into Angular as my first JS frontend framework in college and internships, only using what RXJS I could grab ahold of. Only relatively recent in my job I have taken steps to learn reactivity in a structured way, and this book is a great piece of that foundation. Experienced with Angular or not, this book is as good of an introduction as it is a refresher.Straight to the point, the recipes CRUD app that is built (with repository for reference for each chapter) is a good talking point for the varying aspects of reactivity. A variety of async calls and events for highlighting RXJS, and assorted synchronous state for reference with signals. The preconfigured local server that accompanies the project was especially nice, so I could focus purely on the frontend and how it alone can shape what comes from and is sent to the backend. I think overall, if you work with a lot of API calls like I do, this book covers most scenarios I could think of. Case in point: had I read this before my previous sprint, I wouldn't have wasted so much time handling errors incorrectly around `forkJoin`.As cliche as it sounds, I would say this book is good whether you are a beginner or experienced with approaching reactivity in Angular. Beginners, take your time following the example project and messing around with it as you go. And experienced folks, read along and think "wow, I learned this lesson the hard way. I wish I had this book before." And for both groups, keep your copy bookmarked and on the ready.

But as the text comments, it's not for beginners. Coupled with the hindrance that the Kindle edition has some code errors that have not aided the comprehension on my first reading which I as a non angular nor rxjs expert suffered ...But 2 weeks later and some RxJS angular programming in between have allowed me to really enjoy and value the book

Ich war bereits ein Fan von der 1. Auflage: Reaktive Programming ist für viele Entwickler:innen ein Paradigmenwechsel und deswegen kann das Thema recht ansprungsvoll sein. Genau aus diesem Grund bin ich ein Fan von Lamis' Didaktik: Für jedes Thema gibt es praktische Beispiele, die mit reaktiven Mustern bestimmte Probleme lösen. Man sieht also sofort, wozu das ganz gut ist.Daneben deckt die neue 2. Auflage nun auch Signals und das Zusammenspiel mit RxJS ab. Außerdem geht es auch auf den neuen data-flow in Angular ein.Ein Must-Have für alle Angular-Entwickler:innen!
