Is there a way to access the raw http response? about genqlient

[benjaminjkraft]

Two options here that exist today:

First, customize the graphql.Client -- basically, write your own implementation of the interface (likely extending the provided one similar to how auth works) that extracts those extensions. (Actually, we already parse them to a map[string]interface{}.) That works well if you want to, say, retry at a given time, or attach data to the error, or update the context somehow (say, if you want to keep track in some quasi-global way of the last rate limit status). But it doesn't really let you add a field to the response for the caller to handle.

Alternately, the option use_extensions adds a return parameter with the extensions. This was added in #184 (see the issue #183 for a bit of discussion on why it's set up this way). It will work better if you want the caller to handle the extensions.

While writing this I realize we could maybe do better on the second half by letting you make the extensions typed? Something like

# genqlient.yaml
extensions_type: path/to/mypkg.Extensions

package mypkg
type Extensions struct {
  Cost struct { ... } `json:"cost"
}

and then instead of map[string]interface{} you get *mypkg.Extensions. Arguably we could even do that if you don't have use_extensions, just for the benefit of a custom graphql.Client. Not sure how important that is for your use case, but it seems reasonable to add.

use_extensions is perfect, thank you so much. I had no idea it was an option. Resolved my issues
