Hot to remove/move general scope prefix from paths

[ycherniavskyi]

For example, I get the next routes:

 #... scope "/api", AppWeb, as: :api do pipe_through :api scope "/v1", Api.V1, as: :v1 do get "/open-api", OpenApiSpex.Plug.RenderSpec, [], alias: false scope "/otp" do post "/request", OtpController, :request post "/verify", OtpController, :verify end end end #...

and in result I get the next OpenAPI JSON:

{ ... "paths": { "/api/v1/otp/request": { ... }, "/api/v1/otp/verify": { ... } }, ... "servers": [ { "url": "http://localhost:4000", "variables": {} } ], ... }

Is it possible to somehow move the general scope prefix /api/v1 from paths to for example server url?

If it is not possible automatically then, so maybe is it possible to remove the general scope prefix /api/v1 from paths? So then I add it to the server url manually.

Hi @ycherniavskyi, you should be able to adjust the paths by transforming the output of Paths.from_router/1 when you build the %OpenApi{} struct.

Something like:

defmodule MyAppWeb.ApiSpec do alias OpenApiSpex.{Components, Info, OpenApi, Paths, Server} alias MyAppWeb.{Endpoint, Router} @behaviour OpenApi @impl OpenApi def spec do %OpenApi{ servers: [ %{Server.from_endpoint(Endpoint) | url: "/api/v1"} ], info: %Info{ title: "My App", version: "1.0" }, paths: Router |> Paths.from_router() |> Map.new(fn {"/api/v1/"<>path, operations} -> {path, operations} end) } |> OpenApiSpex.resolve_schema_modules() end end

Thank you for your hint!

This is funny, but I end up with almost the same approach!
