How to save cookie set in response to browser?

[timmoti]

I have a Set-Cookie header in my response object with value token=sessiontoken1234; path=/; expires=Thu, 04 May 2023 02:00:29 GMT; samesite=lax; httponly, generated by a koa backend.

Using the browser fetch api, I am able to easily set the cookie in browser with a simple fetch call:
await fetch('http://localhost:4000/set-session', { method: 'GET', cache: 'no-store', credentials: 'include' })

However I am unable to do so via ky:
ky.get('http://localhost:4000/set-session')

I thought I might be able to perform a separate set cookie step in an afterReponse hook but accessing response.headers results in an empty object: Headers: {}. This seems to be the case with the fetch api as well so I think that is the expected behaviour

How do I get ky to set the cookie in the same way as is possible through the fetch api?

Some details:
ky version: 0.33.3
chrome version: 112.0.5615.121 (Official Build) (arm64)

Did you try await ky.get('http://localhost:4000/set-session', { cache: 'no-store', credentials: 'include' })?

Ah yes. That's the reason why. Didn't realise we could use the RequestInit options object from the fetch API in the same way for ky. I looked through the types file and it looked sufficiently different.

Thanks for your help!
