application.ex
children = [
# Start the Telemetry supervisor
Pxf.Web.Telemetry,
# Start the PubSub system
{Phoenix.PubSub, name: Pxf.PubSub},
# Start the Endpoint (http/https)
Pxf.Web.Endpoint,
# Start a worker by calling: Pxf.Worker.start_link(arg)
# {Pxf.Worker, arg}
Pxf.Scheduler,
# web server plug
{Plug.Cowboy, scheme: :http, plug: Pxf.Router, options: [port: 8000]}
]
