§Play Tutorials

Play’s documentation shows the available features and how to use them, but the documentation will not show how to create an application from start to finish. This is where tutorials and examples come in.

Tutorials and examples are useful for showing a single application at work, especially when it comes to integrating with other systems such as databases or Javascript frameworks.

The play-samples GitHub repository offers Play examples that cover a huge number of cases. There you can find projects in Java, Scala and for multiple versions of Play. You can pick one that demonstrates functionality of interest to you. Make sure you have verified the requirements for running Play. You can either clone the play-samples GitHub repository or download its contents as zip file. The examples cover the following topics:

§Java

§Scala

§Third Party Tutorials and Templates

The Play community also has a number of tutorials and templates that cover aspects of Play better than the documentation can, or has a different angle. Templates listed here are not maintained by the Play team, and so may be out of date.

This is an incomplete list of several helpful blog posts, and because some of the blog posts have been written a while ago, this section is organized by Play version.
