title: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
body: <p>I am using nodejs server, express framework and fetch library  to send request to another server which is in different domain. For one of my endpoint consider (localhost:8080/login) i am rendering ejs file when the user clicks login button i am sending a fetch request to an api (https:otherserver.com/login) different server which is in other domain. i am not able to send this request. I am getting this error :</p>
  
  <p>Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '<a href="http://localhost:8080" rel="noreferrer">http://localhost:8080</a>' is therefore not allowed access. The response had HTTP status code 404. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.</p>
  
  <p>I am not sure how to handle this issue. please suggest some ideas or links which can solve this issue.</p>
