==============
SockJS-Twisted
==============
A simple library for adding SockJS support to your twisted application.
Status
======
SockJS-Twisted passes all `SockJS-Protocol v0.3.3 <https://github.com/sockjs/sockjs-protocol>`_ tests,
and all `SockJS-Client qunit <https://github.com/sockjs/sockjs-client>`_ tests. It has been used in
production environments, and should be free of any critical bugs.
Usage
=====
Use ``txsockjs.factory.SockJSFactory`` to wrap your factories. That's it!
.. code-block:: python
from txsockjs.factory import SockJSFactory
reactor.listenTCP(8080, SockJSFactory(factory_to_wrap))
There is nothing else to it, no special setup involved.
Do you want a secure connection? Use ``listenSSL()`` instead of ``listenTCP()``.
Advanced Usage
==============
For those who want to host multiple SockJS services off of one port,
``txsockjs.factory.SockJSMultiFactory`` is designed to handle routing for you.
.. code-block:: python
from txsockjs.factory import SockJSMultiFactory
f = SockJSMultiFactory()
f.addFactory(EchoFactory(), "echo")
f.addFactory(ChatFactory(), "chat")
reactor.listenTCP(8080, f)
http://localhost:8080/echo and http://localhost:8080/chat will give you access
to your EchoFactory and ChatFactory.
Integration With Websites
=========================
It is possible to offer static resources, dynamic pages, and SockJS endpoints off of
a single port by using ``txsockjs.factory.SockJSResource``.
.. code-block:: python
from txsockjs.factory import SockJSResource
root = resource.Resource()
root.putChild("echo", SockJSResource(EchoFactory()))
root.putChild("chat", SockJSResource(ChatFactory()))
site = server.Site(root)
reactor.listenTCP(8080, site)
Multiplexing [Experimental]
===========================
SockJS-Twisted also has built-in support for multiplexing. See the
`Websocket-Multiplex <https://github.com/sockjs/websocket-multiplex>`_ library
for how to integrate multiplexing client side.
.. code-block:: python
from txsockjs.multiplex import SockJSMultiplexResource
multiplex = SockJSMultiplexResource()
multiplex.addFactory("echo", EchoFactory())
multiplex.addFactory("chat", ChatFactory())
root = resource.Resource()
root.putChild("multiplex", multiplex)
site = server.Site(root)
reactor.listenTCP(8080, site)
If you want PubSub functionality, just use ``txsockjs.multiplex.SockJSPubSubResource`` instead!
Options
=======
A dictionary of options can be passed into the factory to control SockJS behavior.
.. code-block:: python
options = {
'websocket': True,
'cookie_needed': False,
'heartbeat': 25,
'timeout': 5,
'streaming_limit': 128 * 1024,
'encoding': 'cp1252', # Latin1
'sockjs_url': 'https://d1fxtkz8shb9d2.cloudfront.net/sockjs-0.3.js'
}
SockJSFactory(factory_to_wrap, options)
SockJSMultiFactory().addFactory(factory_to_wrap, prefix, options)
SockJSResource(factory_to_wrap, options)
SockJSMultiplexResource(options)
SockJSPubSubResource(options)
websocket :
whether websockets are supported as a protocol. Useful for proxies or load balancers that don't support websockets.
cookie_needed :
whether the JSESSIONID cookie is set. Results in less performant protocols being used, so don't require them unless your load balancer requires it.
heartbeat :
how often a heartbeat message is sent to keep the connection open. Do not increase this unless you know what you are doing.
timeout :
maximum delay between connections before the underlying protocol is disconnected
streaming_limit :
how many bytes can be sent over a streaming protocol before it is cycled. Allows browser-side garbage collection to lower RAM usage.
encoding :
All messages to and from txsockjs should be valid UTF-8. In the event that a message received by txsockjs is not UTF-8, fall back to this encoding.
sockjs_url :
The url of the SockJS library to use in iframes. By default this is served over HTTPS and therefore shouldn't need changing.
