What’s the safest way to shut down a Play Framework application?

What is the safest and most recommended method for shutting down a Play Framework application to ensure that all resources are properly released and no data is lost or corrupted during the process?

The safest way to shut down a Play Framework application is to use the Coordinated Shutdown feature. This ensures that all resources are properly released and no data is lost or corrupted during the process1. Here's how you can do it:

Use Coordinated Shutdown: Play Framework incorporates Akka's Coordinated Shutdown, which provides a set of phases for gracefully shutting down the application. You can register tasks to be executed during these phases1.

Invoke Server#stop: To stop the server, you should call the Server#stop method. This will stop the server and also stop the application running on that server1.

Invoke Application#stop: To stop the application, you can call the Application#stop method. This will stop the application and may also stop the server where the application is running1.
