websocket - Using Socket.io to emit and receive messages on the client -

so using socket.io send messages , forth.

i use socket raise events , catch them within client itself. far, have tried (in chrome console i.e. client):

socket.on('news', function(data) {   console.log(data); }); 

but, when ran following (from chrome console):

socket.emit('news', {my: 'data'});

i did not console.log message.

could please me achieve desired result ?

the code below:

socket.on('news', function(data) {   console.log(data); }); 

runs in server application should see them in cmd (windows) instead of browser. safe hard code socket.emit('news', {my: 'data'}); in client application/script if can't still see log in terminal. socket.io might not available in window if way.

if want raise event , catch them within client, can this:

server:

socket.on('news', function(data){     var msg = data + 'world';     socket.emit('news-response', msg);  }); 

client:

socket.emit('news', 'hello');  socket.on('news-response', function(data){     console.log(data);   //should output 'hello world' });
