The default execution context provided by Play. You should use this for non-blocking code only. You can do so by passing it explicitly, or by defining an implicit in your controller like so:

implicit lazy val executionContext = defaultExecutionContext

The default FileMimeTypes provided by Play. Used to map between file name extensions and mime types.

The MessagesApi provided by Play. This can be used to provide the MessagesApi needed by play.api.i18n.I18nSupport.

The default body parsers provided by Play. This can be used along with the Action helper to customize the body parser, for example:

def foo(query: String) = Action(parse.tolerantJson) { request =>
  Ok(request.body)
}

Retrieve the flash scope implicitly from the request.

For example:

def index(name:String) = Action { implicit request =>
  val message = request2flash("message")
  Ok("Got " + message)
}

Retrieves the session implicitly from the request.

For example:

def index(name:String) = Action { implicit request =>
  val username = request2session("username")
  Ok("Hello " + username)
}

The default Langs provided by Play. Can be used to determine the application's supported languages.

Convenient extractor allowing to apply two extractors. Example of use:

request match {
  case Accepts.Json() & Accepts.Html() => "This request accepts both JSON and HTML"
}
