Possible to use websharper as a drop-in JS replacement?

Is it possible to use websharper as a drop-in replacement for javascript without the additional complexity of sitelets or ASP.NET?

For example, can I compile the following websharper library to a .js file and call the hello() function from within a javascript script block in my html?

namespace WebSharperLib

open IntelliFactory.WebSharper

module HelloWorld =
  [<JavaScript>]
  let hello () =
    IntelliFactory.WebSharper.JavaScript.Alert("Hello World")
Solution

  • You can indeed do something like that. The solution i found is as following :

    • Create a WebSharper library project in VS
    • Paste the code in your example
    • Generate the solution

    • Copy the last line of the solution generation (where it runs websharper) and run it in powershell/console just adding the option

      -js name of your js file

    The thing is, this way you don't have any of the compiled dependencies. I guess you can get them if you make a full project and go grab the compiled js output there.

    Tt seems to me WebSharper is not made to be used this way, but rather as a full package.

    If you just want F# compilation to Javascript, there is Pit that is made exactly for that purpose, so i suggest you try that first.
