## Conditional OpenAPI from settings and env vars { #conditional-openapi-from-settings-and-env-vars }

You can easily use the same Pydantic settings to configure your generated OpenAPI and the docs UIs.

For example:

{* ../../docs_src/conditional_openapi/tutorial001_py310.py hl[6,11] *}

Here we declare the setting `openapi_url` with the same default of `"/openapi.json"`.

## JavaScript-only settings { #javascript-only-settings }

Swagger UI also allows other configurations to be **JavaScript-only** objects (for example, JavaScript functions).

FastAPI also includes these JavaScript-only `presets` settings:

```JavaScript
presets: [
    SwaggerUIBundle.presets.apis,
    SwaggerUIBundle.SwaggerUIStandalonePreset

        searchBody.put("name", "test_webconfig");
        String res = checkMethodBase(searchBody).get("/api/admin/webconfig/settings").asString();
        List<String> webConfigList = JsonPath.from(res).getList("response.settings.findAll {it.name.startsWith(\"test_webconfig\")}.id");
        return webConfigList.get(0);
    }

    @AfterEach
    void deleteWebConfig() {
        final Map<String, Object> searchBody = new HashMap<>();

the scanner will sleep *10x* the time each operation takes.

In most setups this will keep the scanner slow enough to not impact overall system performance. Setting the `delay` key to a *lower* value will make the scanner faster and setting it to 0 will make the scanner run at full speed (not recommended in production). Setting it to a higher value will make the scanner slower, consuming less resources with the trade off of not collecting metrics for operations like healing and disk usage...
