Cannot use more than one client to access the methods in a route

[opensourcegeek]

In the below code (WebsocketAPI -> getDevices) when I emit the payload(res.socket.emit(payload)) it works fine when I have just one client attached. When I have another client, only one of them get the payload. I tried invoking emit method on req.socket and res.socket both seem to play up.

When I use res.json(payload) all the clients attached get the data. Since getDevices method is invoked when a client initially connects to the server, any time a new client gets connected to server, the server pushes the payload to all the clients attached. I'm not sure where I'm going wrong. Thanks

// actual API implementation
export class WebsocketAPI {
    constructor(dbService, db) {
        console.log(this.onData);
        this.api = new APIInterface(dbService,
            db,
            this.onData.bind(this));
        this.connectedClients = {};
    }

    getDevices(req, res) {
        return this.api.getDevices().then((payload) => {
            //req.io.respond(payload);
            console.log(req.socket);
            //req.socket.emit(payload);
            res.socket.emit(payload);
        });
    }
}


// setting up routes
export function websocketSetup(app, dbService, db) {
    let webSocketAPI = new WebsocketAPI(dbService, db);
    console.log('Setting up websocket');

    app.io.route('ax-devices', {
        getAll: (req, res) => {
            console.log('getAll called');
            return webSocketAPI.getDevices(req, res);
        }
    });

    app.io.route(constants.AX_DEVICE_WRITE, (req, res) => {
        console.log('Write called');
        return webSocketAPI.write(req, res);
    });
