# CaddyServer

## Start Caddy Server by `Port`

Start in Application supervisor

```elixir
def start(_type, _args) do
    children = [
      # Start the Telemetry supervisor
      PhoenixWeb.Telemetry,
      # Start the PubSub system
      {Phoenix.PubSub, name: PhoenixWeb.PubSub},
      # Start the Endpoint (http/https)
      PhoenixWeb.Endpoint,
      # Start a CaddyServer by calling: CaddyServer.start_link([])
      {CaddyServer, []}
    ]

    # See https://hexdocs.pm/elixir/Supervisor.html
    # for other strategies and supported options
    opts = [strategy: :one_for_one, name: PhoenixWeb.Supervisor]
    Supervisor.start_link(children, opts)
  end
