Reactive programming is a set of techniques for implementing scalable, resilient and responsive systems as per the Reactive Manifesto. Such systems are based on asynchronous message-passing, and their basic building-blocks are event handlers. This course teaches how to implement reactive systems in Scala and Akka by using high-level abstractions, such as actors, asynchronous computations, and reactive streams.

This module further explores the Actor model by showing useful patterns used to create complex and resilient programs
What's included
3 videos2 programming assignments
Actors allow you to decouple a program in units that can be distributed on a single or on multiple machines. This module elaborates on the power and the consequences of distributed computation

Now that you are familiar with the Actor model, this module shows how to leverage Scala's powerful type system to write programs with more confidence by using typed actor descriptions
What's included
6 videos2 programming assignments
This module introduces the concept of data streams and the basic semantics of stream processing before showing how the Akka framework can be used to tackle common challenges in this domain
What's included

Great at teaching theory. I had to watch a bunch of RockTheJVM videos to learn how to actually program Akka, though.

Pretty hard, especially week 5. Only do the assignments if you are up to a challenge.

Good course, quite difficult but rewarding. I think textual descriptions for some of the exercises could be improved a little bit(kvstore).

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
