Spray Pass a Scala Value to a Resource

I am trying to use Spray to fulfill my routing needs for a Scala based web application. I'm wondering how you can pass a Scala val to a front end resource, such as using a variable inside an HTML file. What is the appropriate way to accomplish this? (If this is possible)

My current route code:

val indexRoute =
  get {
    path("") {
      val name = "hello"
      getFromResource("views/index.html")
    }
}

My html: 

<!DOCTYPE html>
<html lang="en">
<body>
  <h1>{name}</h1>
</body>
</html>

This obviously just ends up printing out {name} on the page

I know I can do something like:

val indexRoute = {
  get {
    path("") {
      val name = "hello"
      complete {
        <html>
          <body>
            <h1>{name}</h1>
          </body>
        </html>
      }
    }
  }
}

But I am hoping there is a way to separate the views from the routing logic itself and into their own files. Is this doable or will I need to define HTML inside the routes?

You may try to use Twirl for you needs.

A short example that's taken from the github page examples

@(name: String, age: Int = 42)
<html>
@* This template is a simple html template --- (this text btw. is a comment and is not rendered) *@
<h1>Welcome @name!!</h1>
<p>You are @age years old, @(if(age < 21) <i>shouldn't you be in bed ?!</i> else <i>have a great      evening !</i>)</p>
</html>
