Class Method Details

.call(url, props) ⇒ UniversalRenderer::SSR::Response?

Performs a POST request to the SSR service to retrieve the complete SSR content. This is used for non-streaming SSR, where the entire payload is fetched before the main application view is rendered.

Emits a render.universal_renderer notification for every attempt and routes failures through config.on_error.

Parameters:

  • url (String) —

    The URL of the page to render on the SSR server. This should typically be the request.original_url from the controller.

  • props (Hash) —

    A hash of props to be passed to the SSR service. These props will be available to the frontend components for rendering.

Returns:
