trait ServerApp extends ProcessApp
Starts a server and gracefully terminates at shutdown. The server
is terminated and the shutdown task is run either by a JVM shutdown
hook or an invocation of requestShutdown()
.
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.ProcessApp, where main returns a Process. You can return a Process that runs forever from a ServerBuilder with
.serve
. UseProcess.bracket
to compose resources in a simpler way than overridingshutdown

shutdown(server: Server): Task[Unit]
Return a task to shutdown the application.
Return a task to shutdown the application.
This task is run as a JVM shutdown hook, or when org.http4s.server.ServerApp.requestShutdown is explicitly called.
The default implementation shuts down the server, and waits for it to finish. Other resources may shutdown by flatMapping this task.
