Creating custom js lib binding
websharperextension

Hi, I'm trying to implement a custom W# binding for the amplify.js. I'm wondering how should I reconstruct the 'Request' part of the api in the proper way.

In general working with amplify request module looks like that:

  1. Fist we have to create a request definition: amplify.request.define("resourceName" ..... )

  2. after that I can execute the request: amplify.request("resourceName" ...... )

so, this is how my binding looks like: https://gist.github.com/aph5nt/05598cfe59162646dc54f491773474d7

and the sample usage:

https://gist.github.com/aph5nt/6f8ce2be2268baa3be0ead5409e1c586

unfortunately in the usage sample, the Define is not found.

Now Im wondering, what would be the right structure in my binding.

Any advice ?

I think all you need to modify here is the case. As it is, it is looking for a JavaScript function Amplify.Request.Define, rather than amplify.request.define. If you change the names passed to Class and Static [] to lowercase, then it will generate the correct JavaScript code. WIG will still capitalize the F# version of those names so the user code would be unchanged.

Thanks for reply. But it is not about the lower case (btw, I have fixed that). I can type "Amplify.Request.Define" with intellisense support etc., but when I pass the required params then I suddenly got a compilation error - "The field, constructor or member 'Define' is not defined". please check the image attached: http://imgur.com/a/i8pLx

I think that the problem is about that I have got a class named 'request' and also a static methods with the same name.

    let Request =
        Class "amplify.request"
        |+> Static [
                "define" => ( T<string>?resourceId * RequestType?requestType * T<JQuery.AjaxSettings>?settings ^-> T<unit> )
            ]

    let Amplify = 
        Class "amplify"
        |+> Static [
                "request" => (RequestSettings?settings ^-> T<unit>)
                "request" => (T<string>?resourceId * T<Object<string>>?data * (T<obj> ^-> T<unit>)?callback ^-> T<unit>)
            ]
  • im not using class nesting and I used fully qualified name "amplify.request"
