Juniper

Juniper is a high level computation expression on top of the EPPlus excel package. It includes Expecto test before building the excel report sheets.

Create specific domain using Thoth.Json.Net

To create you own specific domain have to convert your domain sheet data to a string using Thoth.Json.Net.

Here is an example how to implement your Encoder and Decoder in your specific domain:

open Thoth.Json.Net
open System
module DomainIds =
    type LocationId =
    | LocationId of locationId : int
        member this.GetValue = (fun (LocationId id) -> id) this
        member this.GetValueAsString = (fun (LocationId id) -> string id) this
module HeatPrognose =
    open DomainIds
    type Location =
        { Name : string
          LocationId : DomainIds.LocationId
          PostalCode : string }
        static member Encoder(location : Location) =
            Encode.object [ "Name", Encode.string location.Name
                            "LocationId", Encode.int location.LocationId.GetValue
                            "PostalCode", Encode.string location.PostalCode]

        static member Decoder =
            Decode.object
                (fun get ->
                { Name = get.Required.Field "Name" Decode.string
                  LocationId = LocationId (get.Required.Field "LocationId" Decode.int)
                  PostalCode = get.Required.Field "PostalCode" Decode.string})

    type WeatherData =
        { LocationId : DomainIds.LocationId
          Time : string
          WindSpeed : float
          Humidity : float
          Temperature : float
          Visibility : float
          IsFaulty : bool }
        static member Encoder(weatherData : WeatherData) =
            Encode.object [ "LocationId", Encode.int weatherData.LocationId.GetValue
                            "Time", Encode.string weatherData.Time
                            "WindSpeed", Encode.float weatherData.WindSpeed

                            "Visibility", Encode.float weatherData.Visibility
                            "IsFaulty", Encode.bool weatherData.IsFaulty ]
        static member Decoder =
            Decode.object
                (fun get ->
                { LocationId = LocationId (get.Required.Field "LocationId" Decode.int)
                  Time = get.Required.Field "Time" Decode.string
                  WindSpeed = get.Required.Field "WindSpeed" Decode.float
                  Humidity = get.Required.Field "Humidity" Decode.float
                  Temperature  = get.Required.Field "Temperature" Decode.float

                  IsFaulty = get.Required.Field "IsFaulty" Decode.bool })

                           
    type Measure =
        { Value : float
          Description : string

                            "Time", Encode.datetime measure.Time ]

        static member Decoder =
            Decode.object

        static member Decoder =
            Decode.object
                (fun get ->
                { Locations = get.Required.Field "Locations" (Decode.array Location.Decoder)
                  Measures = get.Required.Field "Locations" (Decode.array Measure.Decoder) })
