 > info **Hint** Note that applying `helmet` as global or registering it must come before other calls to `app.use()` or setup functions that may call `app.use()`. This is due to the way the underlying platform (i.e., Express or Fastify) works, where the order that middleware/routes are defined matters. If you use middleware like `helmet` or `cors` after you define a route, then that middleware will not apply to that route, it will only apply to middleware defined after the route.

 #### Overview
 
-In general, each gateway is listening on the same port as the **HTTP server**, unless your app is not a web application, or you have changed the port manually. This default behavior can be modified by passing an argument to the `@WebSocketGateway(80)` decorator where `80` is a chosen port number. You can also set a [namespace](https://socket.io/docs/rooms-and-namespaces/) used by the gateway using the following construction:

-In the example above, the `handleEvent()` function takes two arguments. The first one is a platform-specific [socket instance](https://socket.io/docs/server-api/#socket), while the second one is the data received from the client. This approach is not recommended though, because it requires mocking the `socket` instance in each unit test.

This approach is not recommended though, because it requires mocking the `socket` instance in each unit test.
 
 Once the `events` message is received, the handler sends an acknowledgment with the same data that was sent over the network. In addition, it's possible to emit messages using a library-specific approach, for example, by making use of `client.emit()` method. In order to access a connected socket instance, use `@ConnectedSocket()` decorator.
