Interface ReactRenderPostProcessor

All Superinterfaces:
io.micronaut.core.order.Ordered
public interface ReactRenderPostProcessor extends io.micronaut.core.order.Ordered
Appends to a server-rendered React page once the component has been written.

Implement this to add something to every rendered page without touching the render script -- a development-mode reload listener is the motivating case, and micronaut-views-react-dev ships one.

There is deliberately no HTTP filter equivalent. A @View route's response body is a ModelAndView while filters run, and the markup is not produced until a MessageBodyWriter encodes it, after the last filter. This is the point at which rendered markup exists.

Beans are invoked in Ordered order, after the component's own output and before the writer is flushed.

      void afterRender(Writer writer, @Nullable io.micronaut.http.HttpRequest<?> request) throws IOException

      Parameters:
      writer - the writer the page was rendered to
      request - the request being answered, or null for a render that is not going to a browser -- an email body built by micronaut-email-template is the common case, and usually wants nothing added
      Throws:
      IOException - if writing fails
