cors
Node.js CORS middleware
About this project
cors CORS is a Node.js middleware for Express/Connect that sets CORS response headers. These headers tell browsers which origins can read responses from your server. [!IMPORTANT] How CORS Works: This package sets response headers—it doesn't block requests. CORS is enforced by browsers: they check the headers and decide if JavaScript can read the response. Non-browser clients (curl, Postman, other servers) ignore CORS entirely. See the MDN CORS guide for details.
