Creating a minimal HTTP server using Akka HTTP

In this recipe, we will see how to create a minimal HTTP server using routing DSL. We will also make use of the HttpApp trait, which provides a precooked server ready to be run.

Getting ready

To step through this recipe, we need to import the Hello-Akka project; all the other prerequisites are the same as before. We need to get the required dependencies for http this time.

How to do it...

For this recipe, perform the following steps:

1. Get the required dependencies. 
2. Edit the build.sbt file and add the Akka HTTP dependency as follows:

        libraryDependencies += "com.typesafe.akka" % 
          "akka-http_2.11" % "10.0.5"

 

 

3. Now create a file named MinimalHttpServer.scala. Define your server and a small object to run it:

        package com.packt.chapter9

        import akka.http.scaladsl.model.{ContentTypes, HttpEntity}
        import akka.http.scaladsl.server.HttpApp
        import akka.http.scaladsl.server.Directives._
        import akka.http.scaladsl...
