trait ServerApp[F[_]] extends StreamApp[F]
Starts a server and gracefully terminates at shutdown. The server is terminated and the shutdown task is run either by a JVM shutdown hook.
More robust resource management is possible through ProcessApp or
StreamApp, which are introduced in http4s-0.16 and http4s-0.17,
respectively.

(Since version 0.16) Prefer org.http4s.util.StreamApp, where main returns a Stream. You can return a Stream that runs forever from a ServerBuilder with
.serve. UseStream.bracketto compose resources in a simpler way than overridingshutdown.- Source

shutdown(server: Server[F]): F[Unit]
Return a task to shutdown the application.
Return a task to shutdown the application.
This task is run as a JVM shutdown hook.
The default implementation shuts down the server, and waits for it to finish. Other resources may shutdown by flatMapping this task.
