Node.js: How to set multiple cookies

Question

I've modified the code I got from this thread: How to set a cookie age without using a framework in Node.js?

But it only works for the last variable. How can I have both of them working? Here's the code I've tried so far:

res.writeHead(200, {
    'Set-Cookie':'test1=' + result[1] + '; expires='+new Date(new Date().getTime()+30 * 60000).toUTCString(),
    'Set-Cookie':'test2=' + result[2] + '; expires='+new Date(new Date().getTime()+30 * 60000).toUTCString() // 30 minutes
});

Thank you,

Answer 1

From the node.js docs:

Use an array of strings here to send multiple headers with the same name.

So just do what you're doing but use an array:

res.writeHead(200, {
    'Set-Cookie':['test1=' + result[1] + '; expires='+new Date(new Date().getTime()+30 * 60000).toUTCString(),
                  'test2=' + result[2] + '; expires='+new Date(new Date().getTime()+30 * 60000).toUTCString()] // 30 minutes
});

Answer 2

According to documentation (in my case NodeJS v14):

https://nodejs.org/dist/latest-v14.x/docs/api/all.html#http_request_getrawheadernames

I've tried this:

const cookieTime = 1234567891; //Default Timestamp without ms
const cookieValue1 = "TestVal"; //Cookie Value 1
const cookieValue2 = "AnotherVal"; //Cookie Value 1
const maxAge = 60*60*24; //24h in seconds

const cookieOptions = ";expires="+cookieTime+";domain=.domain.tld;visited=true; Max-Age="+maxAge+"; HttpOnly; Secure";

res.setHeader('Set-Cookie', ['cookie1='+cookieValue1+cookieOptions, 'cookie2='+cookieValue2+cookieOptions]);

This works perfectly fine without any additional modules, despite the obvious ones "http" or "https" for response/request handling in a callback.

Q: Why using res.setHeader() instead of res.writeHead()?

A: In my case, i need to send more data afterwards.

Since my code is ugly here is a snippet of pseudocode:

response = http(s) response from callback

String: Action = 'Set-Cookie'

Array: Cookies = [
     String: 'cookieName=cookieValue;cookieOption=cookieOptionValue;....;',
     String: 'cookieName=cookieValue;cookieOption=cookieOptionValue;....;',
     ....,
     ....
]

response.setHeader(
     String: Action,
     Array: Cookies
)

If you need further information on available actions or cookie options:

-) available response actions

-) available cookie options
