What is Cors

CORS stands for Cross-Origin Resource Sharing.

It's a browser security feature

that restricts web pages from making requests to a different domain (origin) than the one that served the web page.

Example :- Below urls are treated as different domains

http://localhost:3000 ------> UI

http://localhost:3200 ------> Node

same as

www.abc.com ------> UI

www.xyz.com ------> Node
