Documentation about properties for kong.ctx

[luisxkimo]

Hi,

I would like to know if exists any kind of documentation to know all properties and meaning available in kong.ctx and if are the same for ngx.ctx.

I see some example of use it like this:

https://support.konghq.com/support/s/article/how-to-log-response-body-and-upstream-by-using-pre-function-plugin?

Accessing to ngx.ctx.balancer_data, but I can't see any reference of other properties.

Hi @tzssangglass

Thanks for the link, but the documentation there is not enough in terms of available properties for ngx.ctx

[tzssangglass]

In my understanding, kong.ctx >= ngx.ctx, so use kong.ctx in Kong consumer plugins first.

Yes, but the real question is if there is any documentation to check all properties available in this object.

In the link that I shared as example, is using ngx.ctx.balancer_data. I guess that in this case should be kong.ctx.balancer_data, but I would like to know if there are other properties like "balancer_data"
