Yes, absolutely. If so, how? Option 1: Force use of Websockets only. By default, websockets are cross domain. If you force Socket.io to only use that as means to connect client and server, you are good to go. Server sid

Socket.IO is a WebSocket API that's become quite popular with the rise of Node.js applications. The API is well known because it makes building realtime apps, like online games or chat, simple. NGINX 1.3.13 and later and all NGINX Plus releases support proxying of WebSocket connections, which allows you to utilize Socket.IO. The WebSocket protocol allows for full‑duplex, or bidirectional. npm install cors, express, nodemon, socket.io.
