Yes it is a constant, you can assign random ID to each socket.
Please find extract from 1 of my project:

const client = new tbClient({
  host: "your-host",
  publicId: "public-id"
});

const now = Date.now();
const mtd = now-3600000;

const device1 = {
  cmdId: 10,
  entityId: 'your-access-token-1',
  startTs: mtd,
  endTs: now
};

const device2 = {
  cmdId: 11,
  entityId: 'your-access-token-2',
  startTs: mtd,
  endTs: now
};

const MySocket = (props) => {

    const [ connected, setConnected ] = useState(false);

    const openSocket = async () => {

      let token = await client.connect(true);

      if(token){

        setConnected(true);

        client.subscribe(device1, async function(response){


          if(response && response.data){
             console.log('device1', response.data);
          }


        });

      } else {
        setTimeout(() => openSocket(), 5000);
      }

    }

    useEffect(() => {
      if(!connected){ openSocket(); }
    },[connected]);

    return(<div></div>);

}

I just created a new issue #5 , publicId belongs to a public dashboard.
You can connect with user/password auth instead or creating a public dashboard.

Hello,
We have a basic example here for React: https://github.com/acte-technology/thingsboard-js-sdk/blob/master/docs/reactjs.js

For WebSocket, you can run this, and check response from callback:

Thanks for your quick reply, I have use example to connect successful by user and password. I consider about how to check WebSocket id, does it is a const? and how to check response from callback

[thinhvotruong35]

After run your code, I got this error, I think because wronged about the "publicId", does it is the device id?

Thank you, It seems app worked but it say "WebSocket Closed", do you have any idea for this

[AdrienAdB]

Yes, sorry for late reply.
When socket is closed, it's response becomes null.
You can simply run openSocket() if response == null.
