[Question] How to send broadcast message?

How to send broadcast message for all users?
I used before connection.sendUTF(json) with pure node server.
Thank you for answer.

You can get the list of all clients per the API docs, then send a message to each one:

ws.getWss().clients.forEach(client => client.send(payload));

@abhishek11210646 I wouldn't think so, it's O(n)

您可以根据API文档获取所有客户的列表，然后向每个客户发送一条消息：

ws.getWss().clients.forEach(client => client.send(payload));
