| `extraProviders` | This property is optional and lets you specify dependency providers that apply only when rendering the application on the server. Do this when your application needs information that can only be determined by the currently running server instance. |

The `ngExpressEngine()` function returns a `Promise` callback that resolves to the rendered page.

If, for some reason, you are not using an `@nguniversal/*-engine` package, you might need to handle it yourself.

This option is the least intrusive as it does not require any changes to the application.

Here, "request URL" refers to the URL of the request as a response to which the application is being rendered on the server.

For example, if the client requested `https://my-server.com/dashboard` and you are rendering the application on the server to respond to that request, `options.url` should be set to `https://my-server.com/dashboard`.
