#ssr_streaming? ⇒ Boolean?

Determines if SSR streaming should be used for the current request. The decision is based solely on the ssr_streaming_preference class attribute set on the controller.

  • If ssr_streaming_preference is true, streaming is enabled.
  • If ssr_streaming_preference is false, streaming is disabled.
  • If ssr_streaming_preference is nil (not set), streaming is disabled.

Returns:

  • (Boolean, nil) —

    The value of ssr_streaming_preference (true, false, or nil). In conditional contexts, nil will behave as false.
