RxJS is the only major dependency of Angular. If used with expertise, it can
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 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
Students will learn to:
Identify when to use RxJS
Manage asynchronicity more easily
Think in terms of data flow
Wire that data flow declaratively using RxJS observable pipelines
Create correct functionality with less code than the imperative alternative
Understand the few handfuls of RxJS operators that compromise most RxJS code,
and when to reach for other operators.
Make RxJS code communicate clearly to other developers
Who Should Attend?
Decision-makers looking to understand and maximize overall team leverage
against "hard problems" and developerment velocity via expert-level use of
Angular developer responsible for understanding and improving large or complex
applications built with RxJS.
Angular developers looking to improve the correctness and concision of
application code using RxJS.
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. 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: Can the content be customized?
A: For private team classes, we *always* discuss your goals, the class
contents, any specials areas for extra coverage, etc. in advance.
We customize both the contents and length (number of days) to your needs.
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) Training for your team, available now
For corporate groups and other organizations, we offer live in-person instruction.
These teams typically have advanced needs, so we provide customized, hands-on
Before each class, our instructors will listen to your needs in depth and add or
change the class agenda. We can also follow-up a class with consulting
assistance, or combine multiple classes into a longer workshop week.
Contact us about a private class
2) Live-instructor public classes, coming soon
Want to attend as an individual or small group? We are creating public,
open enrollment versions of many of our classes, including this one.
Unlike canned video training, live instructor online classes offer frequent
opportunities for detailed Q&A discussion.
This class isn't quite ready yet, but follow us on social media (bottom of
the page) or keep an eye on our website for announcements. We will show
the schedule of upcoming open enrollment class dates prominently.
