socket.emit vs socket.send

[Linus G Thiel]

Hi,

Could someone in the know care to explain the difference between
socket.send and socket.emit, and when it's appropriate to use them?

socket.emit allows you to emit custom events on the server and client
socket.send sends messages which are received with the `message` event

Hi,

Sorry I think I was confused. socket.send is for regular messages
right, and emit is if you want to send a particular kind of event?

[Guillermo Rauch]

Socket#send should be seen as a low-level api (for custom protocols development, or cases where maximum messages per second speed is crucial), and Socket#emit a higher-level interface (for app development).

Great, thanks!

Could you please shed some light on how namespaces work on the client side?

Do I have to do

var foo = io.connect("http://localhost/foo"),
bar = io.connect("http://localhost/bar");

Or can I utilize the same kind of api as on the server, so

var socket = io.connect();

socket.of("/foo").json.emit("qux", {foo: 1});

?

Hi Guillermo,

Could you give any indication on what is the performance impact of using emit vs send?

If not, I can also benchmark it myself.

Cheers,

Xavier.

I'm using the emit function, socket send always triggering the 'message' event on the client. With socket emit you can create events on your own and trigger them

I know diference between them.

send  is a pure text.

but emit  have event name.

e.g:

emit('eventName', message)

you can see detail on the server side
