defmodule MyApp do
  use Ace.HTTP.Service, [port: 8080, cleartext: true]

  @impl Raxx.Server
  def handle_request(%{method: :GET, path: []}, %{greeting: greeting}) do
    response(:ok)
    |> set_header("content-type", "text/plain")
    |> set_body("#{greeting}, World!")
  end
end

The arguments given to use Ace.HTTP.Service are default values when starting the service.

config = %{greeting: "Hello"}

MyApp.start_link(config, [port: 1234])

Here the default port value has been overridden at startup

Ace implements the Raxx HTTP interface. This allows applications to be built with any components from the Raxx ecosystem.

Raxx has tooling for streaming, server-push, routing, api documentation and more. See documentation for details.

The correct version of raxx is included with ace, raxx does not need to be added as a dependency.

If a service is started without the cleartext it will start using TLS. This requires a certificate and key.

config = %{greeting: "Hello"}
options = [port: 8443, certfile: "path/to/certificate", keyfile: "path/to/key"]

MyApp.start_link(application, options)

TLS is required to serve content via HTTP/2.

The normal way to run services is as part of a projects supervision tree. When starting a new project use the --sup flag.

mix new my_app --sup

Add the services to be supervised in the application file lib/my_app/application.ex.

defmodule MyApp.Application do
  @moduledoc false

  use Application

  def start(_type, _args) do
    import Supervisor.Spec, warn: false

    children = [
      {MyApp, [%{greeting: "Hello"}]}
    ]

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
end

Start project using iex -S mix and visit http://localhost:8080.

Run h2spec against the example hello_http2 application.

1. Start the example app.

cd examples/hello_http2
iex -S mix

2. Run h2spec from docker

sudo docker run --net="host" summerwind/h2spec --port 8443 -t -k -S
