EncodeJSONResponse is a default implementation of a function that consumers can also provide themselves. Does anything prevent that, here?
No, I'm wondering if a default implementation could have the same feature than the HTTP one.

So I'd like to try to avoid the situation where default implementations provided by Go kit, like this function, being continuously updated with new features/capabilities of their underlying systems. I see that as unsustainable, as well as unnecessary: Go kit is designed specifically to allow consumers to provide their own EncodeJSONResponse functions.
Can you suggest some wording for the docs that would make this clear?
Something like
Go kit provides default implementation for many functions (for instance
http.EncodeJSONResponse
,nats.EncodeJSONResponse
,http.DefaultErrorEncoder
,nats.DefaultErrorEncoder
,...) but is designed to allow consumers to provide their implementation (maybe to use the latest features of the underlying systems).
?
SGTM
Can you suggest "where" to put this sentence in the documentation?
What would you like?
Overview
Since release
v1.11.0
, nats.go supports message headers. headers are very useful to transfer metadata together with messages.I'm proposing to add basic support for headers in the default response encoder.
Proposed API
The idea is to do something similar it's done for
transport/http
with theHeaderer
interface. API change proposal is backward compatible (no public API change)If the proposal is accepted I can raise a PR
