We are happy to announce the release of WebSharper 3.6.6. Here are the main highlights.

Cookies library

We integrated a library to facilitate the management of cookies on the client side. It is available under WebSharper.JavaScript.Cookies. Here is a small example:

open WebSharper
open WebSharper.JavaScript

[<JavaScript>]
let testCookies() =

    // Set a cookie
    Cookies.Set("key", "value")

    // Set a secure cookie which expires in a day
    Cookies.Set("key", "value",
        Cookies.Options(
            Secure = true,
            Expires = System.DateTime.Now.AddDays(1.).JS))

    // Get a cookie
    let value = Cookies.Get("key")
    
    // Delete a cookie by setting it to expire immediately
    Cookies.Expire("key")

Require resources in server-side markup

It can sometimes be useful to depend on a resource, such as a CSS file, without having any client-side markup. This is now possible using a WebSharper.Web.Require control.

open WebSharper

// Let's say you have a resource defined:

type MyResource() =
    inherit Resources.BaseResource("style.css")

[<assembly: System.Web.UI.WebResource("style.css", "text/css")>]
do ()

// And you want to include it in your page that doesn't contain client-side code.

// Using UI.Next:
open WebSharper.UI.Next
open WebSharper.UI.Next.Html
open WebSharper.UI.Next.Server

let styledElement() =
    div [
        text "A page containing this element will include style.css"
        Doc.WebControl (Web.Require<MyResource>())
        // Or equivalently:
        Doc.WebControl (Web.Require(typeof<MyResource>))
    ]

// Using WebSharper.Html:
open WebSharper.Html.Server

let styledElement() =
    Div [
        Text "A page containing this element will include style.css"
        Web.Require<MyResource>()
        // Or equivalently:
        Web.Require(typeof<MyResource>)
    ]

That's it for the main new features; here is the full change log.

WebSharper

  • #491: Remove reference from WebSharper.Sitelets.dll to WebSharper.Compiler.dll
  • #498: Add WebSharper.Web.Require (see above).
  • #502: Add client-side Cookies library (see above).
  • #503: Window inherits from EventTarget, allowing the use of AddEventHandler on JS.Window.
  • #504: MSBuild task: force loading the right version of FSharp.Core in the appdomain.
  • #506: In unpack task, use $(OutDir) if set.
  • #507: Honor optional arguments Async.AwaitEvent(?cancelAction) and Async.StartChild(?timeout).
  • #508: bind multiple-argument versions of JSON.Stringify.
  • #509: Fix JSON.Serialize macro for recursive types.
  • Add missing proxies for querySelector and querySelectorAll on Window and Dom.Element.
  • Add proxy for System.TimeoutException.
  • Always extract resources when WebSharperProject is Site, thus fixing WebSharper.Suave #7.

WebSharper.UI.Next

  • #60: Templating: allow using the same simple text hole in multiple places.
  • #65: Make sure to set the selected element after rendering the select box.

Happy coding!
