Add JWT authentication to a LB4 Socket App

[baltameme]

I have built a simple chat based on the example shared in the following repo:
https://github.com/raymondfeng/loopback4-example-websocket/

What i am trying to do now is closing the connection over this App so it can be allowed through specific authenticated users. I want to enquire how can i integrate the JWT authentication as part of the socket app life cycle.

Hey @baltameme

You might want to pose your question on https://stackoverflow.com/ with tags loopback and websocket.

@baltameme I wonder if you have the JWT token validation up connect. See https://github.com/raymondfeng/loopback4-example-websocket/blob/master/src/controllers/websocket.controller.ts#L18

Hey @raymondfeng, yeah i've noticed that you're using websocket.controller.ts for exposing the socket connections. However, i want to enquire if its possible to following coding strategy in the following reference, where i can just append the (authenticate) decorator as the following:

@ws.connect()
@authenticate('jwt')
connect(socket: Socket) {
console.log('Client connected: %s', this.socket.id);
socket.join('room 1');
}
