如何在不同的节点 js 路由上设置 cookie？

Question

I'm developing a user based project, using node ( express, mongoose etc. )

I currently use JWT and the token has the user id in it, I know how to send a cookie when someone logs in, but I don't know how to make the cookie work on all routes, like basically when a user is logged in and goes on route /test the cookie is still there.

I think what I'm trying to achieve is called "session/cookie based authentication", could be wrong idk.

Once you set a cookie, from within any route, with

const myCookieValue = 'whatever'
res.cookie('myCookieName', myCookieValue, {
  maxAge: 3600*1000, /* one hour */
  httpOnly: true
})

you can retrieve its value, from within any route, with

const myCookieValue = req.cookies.myCookieName || 'yo! no cookie! something is wrong!'

The cookie-parser package makes this possible, handling the gnarliness of the the HTTP header for you.
