RxJS is the only major dependency of Angular. If used with expertise, it can
help make Angular applications more concise, correct, and comprehensible. Yet
RxJS’s merits are often underappreciated because it can be complex and
challenging to learn in depth.
At Oasis Digital, we’ve used RxJS in great depth across numerous projects
since 2015 and have introduced thousands of students to RxJS in our popular
Angular Boot Camp. This new RxJS class more fully explores the power of RxJS to
reveal its full benefits. The class includes:
Expert explanation and discussion
Clear, isolated examples for precise understanding
Complex, realistic examples - real scenarios and how to express them optimally
If you only get these eight operators, look how much better off you are
Students will learn to:
Manage asynchronicity more easily
Think in terms of data flow
Wire that data flow declaratively using observable pipelines
Create correct functionality with less code than the imperative alternative
Improve developer productivity
Make RxJS code communicate clearly to other developers
Who Should Attend?
This course is geared toward Angular developers who would like to improve their RxJS usage beyond the basics.
Prerequisites / requirements
Several months of experience with Angular
Editor and other tools to work on TypeScript source code
A computer—this is a hands-on workshop
Ability to install software, including Node, NPM, and packages
We have trained thousands of developers at hundreds of companies,
including numerous global leaders.
Introduction and background
Oasis Digital introduction, student introduction
TypeScript, the language used throughout
Why use RxJS, if it is possible to avoid it?
Why is Angular built on RxJS?
Angular and RxJS
RxJS's place in the world
To Observable or to Promise? What's the difference?
Thinking reactively (in the sense of reactive programming)
hot vs cold observables
Use same abstraction for input from user and other applications
Building reactive data flows
Calculating derived data from two api calls
Reactive forms input, round trip to server, then put the data on the screen
Incremental search with flaky backend
RxJS as a state management tool
Calculating derived state from ngrx
Making your own observables
Following Redux/Ngrx pattern
Observable Operator Theory
Conditional and boolean operators
Mathematical and aggregate operators
Implementing the Observable Spec
Older observables syntax
Oasis Digital instructors have extensive experience with both
Angular and numerous surrounding technologies; here are some
of them. The specific instructor(s) assigned to your class will
depend on which class or class topics (we customize!) are
put together, availability, additional consulting needs, etc.
Q: Is this taught "in person"?
A: We offer training both in-person and online via remote conferencing.
Q: How does the remote option work?
A: Much like an in-person class, it is conducted by our expert trainers, in real time.
The trainers can answer questions, assist with trouble students are having, etc.
We strive to offer as much of the in-person experience as possible, online.
Q: Are there open enrollment public classes?
A: We currently only offer an open-enrollment "public" class for our flagship
Angular Boot Camp.
Q: How does the recorded class work?
A: In a recorded class, the biggest obstacle is the lack of live question-and-answer
To deliver a great result, we practice teaching with live groups before
creating the recorded class. In this way, we aim to answer as many of the common
(and less common) questions as possible. We also do as much "live coding" as makes
sense for the topic, in a recorded class.
Q: Can we schedule a private class any time?
A: Our classes are taught by developers who use the subject technologies in their daily work,
so we don't assign "any" available developer/trainer to any particular class,
but only to classes with a strong experience and knowledge match.
Please contact us to arrange a date.
Training for your team, available now
For corporate groups and other organizations, we offer live, in-person instruction.
These teams typically have advanced needs and are looking for hands-on assistance,
so for larger groups we send two expert instructors. Each private class is preceded
by a technical discussion so that we can understand your needs and customize the
content to deliver maximum value.
Classes can be customized, combined, and augmented with consulting to assist
your team in implementing the ideas in your environment.
