Cookies don't get stored in localhost

Question

I'm trying to set a cookie when a user logs into the application but i can't seem to get the cookie to get stored on chrome or firefox but it does work on postman.

Here is the part of the code when i try to set my cookie.

  res.cookie("jwt", token, {
    domain: ".localhost",
    path: "/",
    expires: new Date(
      Date.now() + process.env.JWT_COOKIE_EXPIRES_IN * 24 * 60 * 60 * 1000
    ),
    httpOnly: true
  });

POSTMAN output :

And my CORS setup :

Note : my server is on port 3900 and my client is on 3000

try omitting the domain part when setting cookies on localhost, check this answer for more infos: https://stackoverflow.com/questions/1134290/cookies-on-localhost-with-explicit-domain — Paolo, Aug 04 '19 at 18:31
just to double check, considering that this is a HTTP only cookie, how did you check that you don't have it in the browser? — 5ar, Aug 04 '19 at 21:01
it is an HTTP only cookie , as for the browser i opened developers tools > application > cookies > my domain — CHADTO, Aug 04 '19 at 22:59

use localhost:3000 as domain because it is your actual domain for client side. localhost by default take port 80 as http request.

res.cookie("jwt", token, {
    domain: ".localhost:3000",
    path: "/",
    expires: new Date(
      Date.now() + process.env.JWT_COOKIE_EXPIRES_IN * 24 * 60 * 60 * 1000
    ),
    httpOnly: true
  });
