Slumber - An F# REST framework

Slumber is a small framework for creating REST applications in a functional style using F#, inspired heavily by the excellent OpenRasta.

The short, short version...

The wiki contains a more detailed overview of Slumber, but a short overview is given below.

Some business logic:

module People = 
  let getPeople () = ...
  let getPerson (id : Int32) = ...
  let createPerson (model : Person) = ...
  let updatePerson (id : Int32) (model : Person) = ...
  let search (term : String option) = ...
  
module Security = 
  let authenticate (req : Request) = ...

Configured in Slumber:

type Config () = 
  interface IContainerDescription with
    member this.Describe baseUrl = 
      containerAt (relativeUrl baseUrl "/api")
      |> authenticatedBy Security.authenticate true
      |> with' (
        endpointAt "/people"
        |> named "people"
        |> supporting (public' get People.getPeople)
        |> supporting (post People.createPerson)
      )
      |> with' (
        endpointAt "/people/search"
        |> named "people-search"
        |> supporting (public' get People.search)
      )
      |> with' (
        endpointAt "/people/{id}"
        |> named "person"
        |> supporting (public' get People.getPerson)
        |> supporting (put People.updatePerson)
      )
      |> reading MediaTypes.Text.Xml Xml.read
      |> writing MediaTypes.Text.Xml Xml.write
      |> reading MediaTypes.Application.Json Json.read
      |> writing MediaTypes.Application.Json Json.write
      |> forwarding MediaTypes.Text.Html MediaTypes.Text.Xml

Exposed as REST services:


GET http://localhost/app/people/search?term=Smith

=>

200 Ok
<people>
  <person>
    <name>John Smith</name>
    <url>http://localhost/app/people/1</url>
  </person>
  <person>
    <name>Jane Smith</name>
    <url>http://localhost/app/people/2</url>
  </person>
</people>
