How does server side cookie parsing work on the with-firebase-authentication example?

[devth]

I read through the source of with-firebase-authentication. It uses js-cookie to read and write cookies. However, when I try this in my app cookies are always undefined on the server side. I can see the cookie in in req.headers.cookie server side, but js-cookie does not magically obtain that value. I don't see wire-firebase-authentication parsing the cookies anywhere so I don't understand how it could actually work. Am I missing something?

Thanks 🙏

js-cookie is for handling browser cookies, not on the server-side. They pass the token as a header to the backend. It looks like they parse req.headers.token, which comes from here.

Thanks @leerob. I was able to solve my issue using next-cookies for server-side.

@leerob @devth I have a question about it.
Does the example need the next-cookies to read/update redux/redux-persist state on server-side?
