Current behaviour

invoke a socket.emit inside a socket.on function does not work. (see code below) socket.on('notification', function (data) { socket.emit('news', { hello: 'world' }); });

Steps to reproduce (if the current behaviour is a bug)

Server side, emit a message from inside a “socket.on” method.

Expected behaviour

Message sent to client

Setup

• OS: Archlinux
• browser: Firefox
• socket.io version: 1.7.2

use io.sockets.emit('news', message) instead of socket.emit

const app = require('http').createServer()
const io = require('socket.io')(app)

io.on('connection', function (socket) {
    socket.on('broadcast', (message)=> {
        const token = socket.request.headers.authorization.replace('Bearer ', '')

        if (token !== '12b3c4d5e6f7g8h9i') {
            return
        }

        // socket.emit('news', message) will not work
        io.sockets.emit('news', message)
    })
})

app.listen(8080)

I just started with socket.io and i have no clue if this is the right way to do this. So perhaps some more seasoned socket.io guru can help us.

Sorry that my above code isn’t clear. I am actually sending a socket.emit('send:action') from another client. The server receives the ‘send:action’ event and should emit the dispatch:action event. I can confirm that my client is emitting properly and that my server is responding, as I mentioned the console.log(action) is working, but the nested socket.emit() is not.
