Send message to specific client

[car1ot]

How to send a message to a specific client? For example, user refill account with money and when transaction with bank is successful, bank send request to my server payments handler with user ID parameters, amount etc.. I want to notify client of successful transaction.

ws.send - you really need to look up the basic things before asking

You need to either store references to the ws objects in Maps by ID and send with ws.send() or you can Subscribe the ws to the user ID in the ws open hander with ws.subscribe(`user/id/${userID}`) and then Publish to that ID with app.publish(`user/id/${userID}`), this works if they have multiple tabs/devices open etc. Unless you only want to send to that specific ws you could use ws.subscribe(`ws/id/${ID}`) @alexhultman is it better to subscribe/publish to a unique ID or store ws objects by ID in JS and use ws.send()?
