Description of Angular 4 RxJs Reactive Programming & FREE Ebook Free Download Udemy Com

The course covers How To Build Angular Applications in  Reactive Style using RxJs and the Observable Pattern,
and its divided into two sections: the first is a deep  dive into the Observable pattern as a way of understanding
RxJs, and the second is a catalog of Angular  Design  Patterns that will allow us to build angular
applications in Reactive Style.

Versions used: The code repository of this  course uses the Angular 4 release, Typescript
2.2 and optionally the Yarn Package manager.

What is Your Biggest Difficulty While Learning Angular  ?

RxJS and Reactive Programming can sometimes be seen as hard to   get into. Although RxJs is optional in many parts of the  Angular API and we can usually use Promises instead,  one of the items of the Angular Project
Roadmap
is to allow to build reactive style  applications, so clearly reactive programming is a topic that
is close to the framework.

What is The Best Way To Learn RxJs ?

Why is RxJs and Reactive Programming sometimes seen as hard to get into ? The main reason for that could be that Observables and reactive programming are often presented as either a programming paradigm shift, an alternative to Promises or a generalization of functions, which are approaches that don’t help as much as we could think in the learning process.

We are going to take an alternative way for learning these concepts: we are going to see that RxJs and Observables are actually a very practical and effective solution to a very common set of problems that we face all the time while building asynchronous programs like user interfaces.

We are going to see that everything around RxJs and Reactive Programming revolves around one fundamental
notion
: The Observable Pattern.

The Best Way To Learn RxJs

We are going to approach reactive programming as a set of application development patterns, that are an evolution of previously existing solutions. So in the first section of the course we will cover the Observable pattern as a design solution for building asynchronous applications that scale well in complexity.

We are going to cover the multiple other satellite concepts around the Observable pattern, namely the Observer and the Subject, and we are also going to learn the benefits of writing applications in Reactive style by implementing our own simplified version of an event bus.

We are then going to see why that does not scale well in complexity, after that we will refactor the application into using the Observable pattern and see how it elegantly solves many of the problems of the initial implementation.

We will also introduce the Store Pattern, see  how it relates to the Observable Pattern. At the of this  section we will then introduce the RxJs library, which at this  point will make a lot more sense given the previous  presentation of the design patterns that its based upon.

What Patterns will be covered in this course ?

With the Observable pattern and its related concepts in place and having introduced the RxJs Library, we are going to see how it can be used to build Angular Applications in Reactive Style.

We are going to cover a set of reactive  patterns for both the View Layer and the Service  layer, by using a set of small applications with a ready to use  backend built in either Firebase or a local HTTP server. The  patterns will be introduced as either implementations from  scratch of a given functionality, or via step-by-step refactorings.

The pattern catalog of the second part of the course will  include: Stateless Observable Services, Smart vs Presentational  Components, Observable Data Services, Nested Subscribe  Anti-Pattern, Data Table Pagination, Local Services, Master Detail With Cached Master Table, Error Handling Components and  Services, Router Data Pre-Fetching (with Loading Indicator),  Container Components, Reactive Forms Draft Pre-Save.

This section also includes a couple of related discussions  concerning application design, like how to avoid Event Bubbling  over the local presentational component tree, and how to use  deeply nested smart components with OnPush change detection.

What Will You Be Able To Do After Taking This Course?

After taking this course you will be comfortable with Reactive  Programming, the Observable Pattern and the RxJs library.

You will be able to reason much more easily about RxJs because you now know the fundamental concepts that it bases itself upon, as well as the design intentions behind it. You will be able to find your way around the documentation and know several commonly used operators. Most of all you know how to build Angular applications in Reactive Style using the RxJs library.

About the course instructor:

Hello, my name is Vasco  and I’m a Software Developer with 17 years of experience, very seasoned building user interfaces with Angular. I’ve worked as a Frontend Developer/Architect in a large variety of enterprise projects throughout the years.

I worked on a ton of projects, everything from single page applications to help build the European Criminal Record Information Exchange System, to brand new e-banking portals, to corporate banking portals, and more. I’ve been a key part of internal framework teams that built frameworks for in-house departments of tens of developers. And that’s just a few of them, please check my Linkedin for extensive recommendations.

I also love to teach, write and talk about technology.  I am looking forward to be your Angular  instructor,

Kind Regards,

Vasco
