Develop real-world Scala applications using concurrency and message passing in an Akka framework with Play web development
Scala is a functional programming language that supports OOP principles and it’s quite challenging to develop scalable and reactive applications without any framework/library support. This video course is designed to help Scala programmers who have very basic knowledge of the Scala language build real-world applications from scratch using the Play and Akka frameworks with the underlined concurrency resolution mechanism.
In this course you will learn various features of the Play and Akka frameworks by building 5 real-world applications with increasing complexity. Beginning with a simple project, a product catalog-listing application, the course will take you through building a customer data entry application, a string processing application to get a word count, a message passing app like Ping pong actors example and Dining-philosophers problem-in humus.
Each project will help you master the programming and data capabilities of Scala. By the end of the course, you will not only be empowered by knowing the ins and outs of Scala, but you will also be able to apply them to solve a variety of problems.
This course is based on writing practical examples using Scala with the Play and Akka frameworks. In this course, you will start by implementing very basic projects for beginner to intermediate-level coders and then explore advanced programming for each of the above frameworks.
What You Will Learn
- Build your first application from scratch using Play and explore the MVC architecture
- Perform database operation using a Slick-JDBC connection with Play
- Design form-based views to record customer data
- Use a pattern to send and receive messages between actors in Akka
- Master the concurrency problem and unblocking behavior of actor systems using the wait and reply mechanism
- Implement features of Akka such as futures, await, timeouts, and ask patterns
- Design and develop an Akka adaptation of the famous ‘dining-philosophers’ problem
- Develop a ping-pong example application using Actor
