Finding the final URL that the request will be redirected to in nodeJS?

Question

I have the following URL:

https://forecast.weather.gov/zipcity.php?inputstring=95014

I would like to figure out which URL it will redirect to. In this example it is:

https://forecast.weather.gov/MapClick.php?CityName=Cupertino&state=CA&site=MTR&lat=37.3042&lon=-122.095

I tried multiple solutions such as:

res.headers.location

and

res.headers.get('location')

But none of them seem to work. I know that the URL redirects because, I could successfully redirect in curl and google-chrome. Here is the code that I am running:

https.get('https://forecast.weather.gov/zipcity.php?inputstring=95014', res => console.log(res.headers.location))

When I was running in curl, I ran the following:

curl -Ls -o /dev/null -w %{url_effective} http://forecast.weather.gov/zipcity.php?inputstring=95014

And got the desired output of:

http://forecast.weather.gov/MapClick.php?CityName=Cupertino&state=CA&site=MTR&lat=37.3042&lon=-122.095

When I run curl:

$ curl -I https://forecast.weather.gov/zipcity.php?inputstring=95014
HTTP/2 302
server: Apache
x-nids-serverid: www1.mo
location: https://forecast.weather.gov/MapClick.php?CityName=Cupertino&state=CA&site=MTR&lat=37.3042&lon=-122.095
x-ua-compatible: IE=Edge
access-control-allow-origin: *

strict-transport-security: max-age=31536000 ; includeSubDomains ; preload

As you can see, there are multiple headers present here that are not present inside nodejs's results:

{
  server: 'AkamaiGHost',
  'mime-version': '1.0',
  'content-type': 'text/html',
  'content-length': '288',
  expires: 'Mon, 26 Apr 2021 19:21:50 GMT',
  date: 'Mon, 26 Apr 2021 19:21:50 GMT',
  connection: 'close',
  'strict-transport-security': 'max-age=31536000 ; includeSubDomains ; preload'
}

I would like to stick to the http module.

All those answers either use another module or look at the header. For some reason the header is not present in my response even though the URL redirects. — Saiansh Singh, Apr 26 '21 at 19:05
`https.get` doesn't seem to follow redirects at least by default, so unless it's a 301/302, the response URL should be the requested one. — Ismail, Mar 16 '22 at 04:59
