Correct way to use task expression in handler

[mjcaley]

Hi,

I'm still learning F# and Falco and I'm using a database library that uses Tasks (Dapper.FSharp). I have a working implementation, but wonder if there's a better way than what I've found.

As an example here's my handler:

let getTemplateHandler: HttpHandler =
    Services.inject<IDbConnection> (fun dbConn ctx ->
        task {
            let route = Request.getRoute ctx
            let id = route.GetInt64 "id"
            let! result = getTemplateService dbConn id

            return
                match result with
                | Some r -> Response.ofJson result ctx
                | None -> (Response.withStatusCode 404 >> Response.ofEmpty) ctx
        })

I wrapped the whole thing in a task expression in order to call the Task APIs. I also found I'm passing around ctx a lot more compared to the examples.

Am I doing something wrong or is there somewhere I can improve?

Thank you!
