can it support CORS policy ?

[arsen2010]

http://localhost:1100 is run on spa-server,
i try to use window.fetch to get JSON file, but occur error:

Access to fetch at 'http://localhost:1100/examples.json' from origin 'http://localhost:1112' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
