logging raw response

[skluz]

I don't see a way to get to the processing chain after Renderer is called. Is there any way to log the raw response?

That can be done from inside a custom Renderer if needed.

Existing renderers, like JsonBody stream response to the client to optimize memory usage.

If you need to log it, you need to render to a memory buffer first (ByteArray or String), then log it and also send to the client. This will increase memory usage and GC work, so not ideal for production.

Another option is to log controller result (most likely Kotlin data class) before rendering it to json.
That can be done from both a custom Renderer or a RequestLogger.
