Play Framework Programming

In the course Play Framework Programming from SpiralTrain participants learn to develop web applications based on the Model View Controller design pattern and using the JVM language Scala.

Intro Play Framework

The course starts with a discussion of the Play Framework architecture. Also discussed is the use of the build and dependency management tool sbt and the command line utility giter8 with which files and directories are generated based on templates.

MVC Model

Next the MVC architecture is discussed and how in Play control flow, data presentation and data storage are realized. Attention is also paid to dynamic URLs and scoped objects in session and flash scope.

Views and Templates

The view in Play web applications is typically based on a template. Attention is paid to the operation of the Scala based template engine and the possible control flow constructs and variables in templates.

Concurrency

Then it's time to handle asynchronous calls and concurrency with multiple threads. The Akka Framework which is ideally suited for concurrent and distributed applications on the JVM, is therefore discussed as well.

Web Services

The course program also treats consuming Web Services in Play. The parsing of JSON data and the parsing of XML data with JAXB and Akka streaming is also explained.

Data Access

Furthermore data access from Play is treated. Object Relational Mapping and both Ebean queries and Rawsql queries are discussed.

Deployment

Finally after an overview of how to create your own Play modules, attention is paid to the deployment of Play Applications on an Apache or Nginx web server.

Audience Course Play Framework Programming

The course Play Framework Programming is intended for experienced developers who want to use the Play Framework for the creation of Web Applications and Web Services.

Prerequisites course Play Framework Programming

Knowledge of and experience with Java, C# or Scala is required to participate in this training.

Realization Training Play Framework Programming

The theory is discussed on the basis of presentation slides. Demos are used to clarify the theory. There is ample opportunity to practice and theory and exercises are interchanged. The course material is in English. Course times are from 9.30 to 16.30.

Certification course Play Framework Programming

After successful completion of the course the participants receive an official certificate Play Framework Programming.
