Oxpecker.OpenApi extends Oxpecker framework with functionality to automatically generate OpenApi spec from code.

Nuget package

Two usages:

open Oxpecker
open Oxpecker.OpenApi

let endpoints = [
    // addOpenApi supports passing detailed configuration
    POST [
        route "/product" (text "Product posted!")
            |> addOpenApi (OpenApiConfig(
                requestBody = RequestBody(typeof<Product>),
                responseBodies = [| ResponseBody(typeof<string>) |],
                configureOperation = (fun o -> o.OperationId <- "PostProduct"; o)
    // addOpenApiSimple is a shortcut for simple cases
    GET [
        routef "/product/{%i}" (
            fun id ->
                |> Array.find (fun f -> f.Id = num)
                |> json
            |> configureEndpoint _.WithName("GetProduct")
            |> addOpenApiSimple<int, Product>



Since Oxpecker.OpenApi works on top of Microsoft.AspNetCore.OpenApi and Swashbuckle.AspNetCore packages, you need to do standard steps:

let configureApp (appBuilder: IApplicationBuilder) =
        .UseSwagger() // for generating OpenApi spec
        .UseSwaggerUI() // for viewing Swagger UI

let configureServices (services: IServiceCollection) =
        .AddEndpointsApiExplorer() // use the API Explorer to discover and describe endpoints
        .AddSwaggerGen() // swagger dependencies
    |> ignore

To make endpoints discoverable by Swagger, you need to call one of the following functions: addOpenApi or addOpenApiSimple on the endpoint.

NOTE: you don't have to describe routing parameters when using those functions, they will be inferred from the route template automatically.


This method is used to add OpenApi metadata to the endpoint. It accepts OpenApiConfig object with the following optional parameters:

type OpenApiConfig (?requestBody : RequestBody,
                    ?responseBodies : ResponseBody seq,
                    ?configureOperation : OpenApiOperation -> OpenApiOperation) =
    // ...

Response body schema will be inferred from the types passed to requestBody and responseBodies parameters. Each ResponseBody object in sequence must have different status code. configureOperation parameter is a function that allows you to do very low-level modifications the OpenApiOperation object.


This method is a shortcut for simple cases. It accepts two generic type parameters - request and response, so the schema can be inferred from them.

let addOpenApiSimple<'Req, 'Res> = ...

If your handler doesn't accept any input, you can pass unit as a request type (works for response as well).
