CorsMiddleware class base

Middleware that applies Cross-Origin Resource Sharing (CORS) headers to outgoing responses.

This middleware:

  • allows requests from any origin
  • permits GET, POST, PUT, DELETE, and OPTIONS methods
  • allows the Content-Type and Range request headers
  • exposes Content-Length and Content-Range response headers
  • short-circuits preflight OPTIONS requests

This type is intended for use in route or global middleware pipelines.

Example:

await CorsMiddleware.middleware(request, () async {
  request.response.write('OK');
});
