Overview

This library allows you to run a WebSharper Sitelet application through an OWIN interface, version 1.0. In the terminology of the OWIN specification, WebSharper is a Web Framework and WebSharper.Owin is an adapter layer for it.

After adding the reference to the project all the classes can be found under the WebSharper.Owin module.

Usage

WebSharper.Owin provides its functionality through several extension methods on the IAppBuilder type. They are the following:

UseDiscoveredSitelet : webRoot: string -> IAppBuilder

Inspects the webRoot folder, looking for an assembly in the bin subfolder that contains a WebSharper Sitelet, and runs this Sitelet with webRoot as the root folder.

UseSitelet : webRoot: string * Sitelet<'T> -> IAppBuilder

Runs the provided Sitelet with webRoot as the root folder, using WebSharper metadata loaded from assemblies located in the bin subfolder of webRoot.

UseCustomSitelet : Options * Sitelet<'T> -> IAppBuilder

Runs the provided Sitelet. Allows a more customized setup than the previous methods, for example running a Sitelet whose code isn't located in the bin subfolder of the root folder, or running the Sitelet with a URL prefix.

UseWebSharperRemoting : webRoot: string -> IAppBuilder

Runs the WebSharper Remoting service, allowing WebSharper-compiled client-side code to invoke [<Rpc>]-annotated server-side functions. Note that the Remoting service is automatically run by the above methods UseDiscoveredSitelet and UseSitelet, as well as UseCustomSitelet if options.RunRemoting is set to true.

Notes

This library does not take care of serving the files extracted from WebSharper assemblies, such as the generated JavaScript files, from the file system. You need to use a static files middleware. The example self-hosted Sitelet application uses a middleware available from NuGet as Microsoft.Owin.StaticFiles, as follows:

open global.Owin
open Microsoft.Owin.StaticFiles
open Microsoft.Owin.FileSystems
open WebSharper.Owin

let RunSitelet (appB: IAppBuilder) mySitelet rootFolder =
    appB.UseStaticFiles(
        StaticFileOptions(
            FileSystem = PhysicalFileSystem(rootFolder)))
        .UseSitelet(rootFolder, mySitelet)
