Simply adds socket.io functionality to Django applications by proxying Django behind a Nodejs/SocketIO server.
Any callback function defined in an app_folder is exposed to Socket.IO as the target my_app.callback_fn. See examples below.
python manage.py runserverjs <hostname> <public port> <proxy port> <socket port>
In any Django template that you want a Socket IO connection, add this templatetag to your HEAD:
{% load nodjango %}
<!doctype html>
<html>
<head>
<script type="text/javascript" src="//code.jquery.com/jquery-2.1.1.min.js"></script>
{% socketio_head_scripts %}
</head>
<body>
<button>Click Me</button>
<script type="text/javascript">
socket.on('my_callback', function(data){
console.log(JSON.stringify(data));
});
$('button').on('click', function(){
socket.emit('django', {
'event': 'my_app.change_color',
'callback': 'my_callback',
'color': 'red'
});
});
</script>
</body>
</html>
# my_app/socketio.py
def change_color(color):
# change color
# ...
# profit
return {'result': 42}
pip install django-socketio-events
And then add nodjango to your INSTALLED_APPS.
