Instance Method Details

#fetch_ssr ⇒ Hash?

Fetches Server-Side Rendered (SSR) content for the current request. This method makes a blocking call to the SSR service and stores the result in the @ssr instance variable.

The SSR content is fetched based on the request.original_url and the @universal_renderer_props accumulated for the request.

Returns:

  • (Hash, nil) —

    The fetched SSR data (typically a hash with keys like :head, :body_html, :body_attrs), or nil if the fetch fails or SSR is not configured.
