Fetch API with Cookie

Question

I am trying out the new Fetch API but is having trouble with Cookies. Specifically, after a successful login, there is a Cookie header in future requests, but Fetch seems to ignore that headers, and all my requests made with Fetch is unauthorized.

Is it because Fetch is still not ready or Fetch does not work with Cookies?

I build my app with Webpack. I also use Fetch in React Native, which does not have the same issue.

Answer 1

Fetch does not use cookie by default. To enable cookie, do this:

fetch(url, {
  credentials: "same-origin"
}).then(...).catch(...);
