This is a sample Akka HTTP endpoint keeping an in-memory database of users that can be created and listed.

Sources in the sample:

• QuickstartApp.scala -- contains the main method which bootstraps the application
• UserRoutes.scala -- Akka HTTP routes defining exposed endpoints
• UserRegistry.scala -- the actor which handles the registration requests
• JsonFormats.scala -- converts the JSON data from requests into Scala types and from Scala types into JSON responses

After starting the sample with sbt run the following requests can be made:

List all users:

curl http://localhost:8080/users

Create a user:

curl -XPOST http://localhost:8080/users -d '{"name": "Liselott", "age": 32, "countryOfResidence": "Norway"}' -H "Content-Type:application/json"

Get the details of one user:

curl http://localhost:8080/users/Liselott

Delete a user:

curl -XDELETE http://localhost:8080/users/Liselott
