As you have not added the screenshot from the Browser's Inspector => Network Tab, I am guessing this answer will help you in case my guess is right.

Try setting the below in your front-end project (Angular in your case):

Try setting the below in your back-end project (Node in your case):

Also, verify your updates as in the below screengrab in the Browser's Inspector (Chrome in my case):

Please Note: - The mentioned response headers have special meaning, so kindly look for more info with a simple Google search. Use these settings during your development phase on localhost.

For whoever has down voted this answer, I respect their view, but may I also know the reason please? I have given my time and effort to guess the actual issue and to answer it provided that, the same was mentioned in the answer itself that the question is not fully complete. — Santhosh John, Apr 18 '20 at 15:00
