In the course Play Framework Programming participants learn to develop web applications based on the Model View Controller design pattern and using the JVM language Scala. The Play Framework is open source and increases the productivity of developers by using convention over configuration, hot code reloading and error messages in the browser.
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.
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.
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.
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.
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.
Furthermore data access from Play is treated. Object Relational Mapping and both Ebean queries and Rawsql queries are discussed.
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.
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.
Knowledge of and experience with Java, C# or Scala is required to participate in this training.
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.
After successful completion of the course the participants receive an official certificate Play Framework Programming.

All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.
We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.
The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.
We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.
Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.
The course includes lunch that we use in a restaurant within walking distance of the course room.
The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.
At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.
