Serving an entire directory tree with spray.io - scala

Question

I would like to translate this JS code to Scala, using spray.io.
How can I translate this line below to Scala using spray.io ?
app.use('/', express.static(path.join(__dirname, 'public')));
In other word, how can I serve an entire directory tree using spray.io ?

Answer 1

As comment above says Spray is deprecated. But directives are similar in akka-http. Here is what you probably need (getFromResourceDirectory in your case)
pathPrefix("docs") {
get {
path("swagger.json") {
getFromResource("swagger.json", ContentTypes.`application/json`)
} ~
(pathEnd | pathSingleSlash) {
redirect("docs/index.html", StatusCodes.TemporaryRedirect)
} ~
getFromResourceDirectory("swagger-ui")
}
}

Answer 2

This serves files (recursively) from the directory ./web/
package com.softwaremill.spray.server
import akka.actor.ActorSystem
import spray.routing.SimpleRoutingApp
object Step1Complete extends App with SimpleRoutingApp {
implicit val actorSystem = ActorSystem()
startServer(interface = "localhost", port = 3300) {
get {
path("hello") {
complete {
"Welcome to Amber Gold!"
}
}
} ~
pathPrefix("web" ) {
getFromDirectory("./web/")
}
}
}
