Are Socket.IO messages encrypted?

Whenever a user sends or receives a message, the message will be encrypted or decrypted using an aes256 npm package with the same secret key.

What is the difference between Socket.IO and SignalR?

As mentioned before, both Socket.IO and SignalR support WebSockets and HTTP long polling. However, unlike Socket.IO, SignalR also supports a third transport: Server-Sent Events. Socket.IO offers a simple and easy-to-use API. In comparison, SignalR is more complex and arguably harder to implement.

What is Socket.IO used for?

Socket.IO is a library that enables low-latency, bidirectional and event-based communication between a client and a server. It is built on top of the WebSocket protocol and provides additional guarantees like fallback to HTTP long-polling or automatic reconnection.
