@nilan I'm experiencing CORS problem when I first time using graphcool service in Angular. I got this:

Failed to load <https://subscriptions.ap-northeast-1.graph.cool/v1/chatie>: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '<http://localhost:8100>' is therefore not allowed access. The response had HTTP status code 400. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I'm using apollo-client, Any idea?
