How to secure socket.io using Nodejs and Flutter

I developed app using Nodejs and Flutter with socket.io client. I want to secure the Socket.io during the communication between two users. Any guide or suggestion pls? Thanks.

Solution

  • On Flutter, you can an extra header to your option headers. 'extraHeaders': {HttpHeaders.authorizationHeader: '$accessToken'}

    import 'package:socket_io_client/socket_io_client.dart' as IO;

IO.Socket createSocket(String accessToken) {
  final url = 'https://$yourDomainHere';
  return IO.io(url,
    <String, dynamic>{
      'transports': ['websocket'],
      'rejectUnauthorized': false,
      'autoConnect': false,
      'extraHeaders': {HttpHeaders.authorizationHeader: '$accessToken'}
    });
}
