Enable seamless cross-origin resource sharing with CORS middleware. Configure access controls for domains, credentials, and HTTP methods to prevent browser blocks on cross-origin requests.

Ensure smooth cross-origin resource sharing with the CORS middleware. CORS (Cross-Origin Resource Sharing) is a mechanism that enables resources on a web page to be requested from another domain outside the domain from which the resource originated. In some cases, CORS is necessary to prevent browsers from blocking cross-origin requests for security reasons.


CORS configuration variables:

  • Access-Control-Allow-Origin: Specify the domains allowed to access resources
  • Access-Control-Allow-Credentials: Indicate whether or not the response to the request can be exposed when the credentials flag is true
  • Access-Control-Allow-Methods: Define the HTTP methods (e.g., GET, POST, PUT) permitted for cross-origin requests
