How to use Aws Api Gateway Websocket

[msimonc]

wscat -c wss... connects w/o extra security configs,

but ReactJS client "blocked by CORS policy" on io()

I'm hoping for wss

the error also is not thrown by the method so I must set a timeout then disconnect()....

If I understand correctly, you need to only enable the WebSocket transport:

const socket = io("https://example.com", { transports: ["websocket"] });

Reference: https://socket.io/docs/v3/client-initialization/#transports

You could also configure CORS on the server: https://socket.io/docs/v3/handling-cors/
