Auth to Improve Socket Connection Security

I added authentication for higher proof of socket, to make the application more secure. io connections. Thus, only authenticated users can make a WebSocket connection to the server, making it impossible for unauthorized users to join the chat groups.

I integrated JWT tokens with NextAuth. js, which sends the token from the client to the server at the time of the WebSocket connection handshake. The token is verified on the server side which confirms if a user is actually authenticated and the request is valid and based on that user can connect to the respective chat group(s). If the token is missing or invalid, then refuse the connection.

Background verification introduced for users joining the chat rooms, and only verified users will be able to access them, which, protects private conversations and information. This also improves the security in the chat application and helps in protecting the anonymity and data of the users.
