Serving Individual Routes That are Ready to be Served

[khajavi]

After removing HttpApp, another thing that can make APIs simpler is to have a Server that can serve variable length arguments of individual routes. like this:

object MainApp extends ZIOAppDefault {
   def run = 
     Server.serve(
       Method.GET / "text" -> handler(Response.text("Hello World!")),
       Method.GET / "json" -> handler(Response.json("""{"greetings": "Hello World!"}""")),
       // and so on
     ).provide(Server.default)
}

The Routes is useful to take the last step in making the routes ready to be served, such as handling errors, applying middlewares, sandbox, etc. However, sometimes, we do not need this step, and our routes are ready to be served and all of their error are handled by converting to Response.

It can reduce one level of indirection on use-cases like this:

import zio._

import zio.http._

object HelloWorld extends ZIOAppDefault {
  val textRoute =
    Method.GET / "text" -> handler(Response.text("Hello World!"))

  val jsonRoute =
    Method.GET / "json" -> handler(Response.json("""{"greetings": "Hello World!"}"""))

  // Create HTTP route
  val app = Routes(textRoute, jsonRoute)

  // Run it like any simple app
  override val run = Server.serve(app).provide(Server.default)
}
