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.

Oasis Digital instructors have extensive experience with both
Angular and numerous surrounding technologies. Here are some
of them; for private classes, the specific instructor(s) for your
class will be
selected based on your organization's specific needs and tweaks
to our outline above.
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.
Two ways to learn
1) Online, recorded video course
For some classes, we are working on an online course offering.
It will have numerous short video segments, teaching each topic in detail,
plus longer segments in which we demonstrate the techniques in the use.
This format makes it possible for us to provide great depth of content,
while as a viewer you can carefully study the
portions of interest, and skip those of less interest; or rewatch the
live coding example segments to pick up more nuances.
This content is still in development - if you're interested please contact us
(using the form, or contact information at the bottom of the page).
2) Private workshop
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.
