Sample code:
io.on('connection', socket => { socket.emit('request', /* … /); // emit an event to the socket io.emit('broadcast', / … /); // emit an event to all connected sockets socket.on('reply', () => { / … */ }); // listen to the event });
How to use The following example attaches socket.io to a plain Node.JS HTTP server listening on port 3000.
const server = require('http').createServer(); const io = require('socket.io')(server); io.on('connection', client => { client.on('event', data => { /* … / }); client.on('disconnect', () => { / … */ }); }); server.listen(3000); Standalone const io = require('socket.io')(); io.on('connection', client => { ... }); io.listen(3000);
