自动更新套接字连接数据？ socket.io

Question

我想定期更新发送到所有连接客户端的数据，通过socket.io连接，socket.io是否具有执行此操作的功能或功能？

Answer 1

Yes, you can simply

var io = require('socket.io')();
io.sockets.emit('an event for everybody', { some: 'data' });

If you're not calling this on a specific connection it will broadcast to all connected clients.

Answer 2

Generally, you don't need to worry about synchronising data with Socket.io. Simply because it's bi-directional & event-based. But you still can update stream from server or client side based on events.

Take a look at this article

To make the update periodic (based on time), you can use setTimeout() function in Javascript. More on that in this question
