Remote Procedure call through WebSocket between browser and tornado.

Features
++++++++

* Initiating call client function from server side.
* Calling the server method from the client.
* Transferring any exceptions from a client side to the server side and vise versa.
* The frontend-library are well done for usage without any modification.
* Fully asynchronous server-side functions.
* Thread-based websocket handler for writing fully-synchronous code (for synchronous database drivers etc.)
* Protected server-side methods (starts with underline never will be call from clients-side directly)
* Asynchronous connection protocol. Server or client can call multiple methods with unpredictable ordering of answers.
* If `ujson`_ is installed messages will be serialize/deserialize with it.


Installation
------------

Install via pip::

pip install wsrpc-aiohttp


Install ujson if you want::

pip install ujson



Simple usage
------------

Add the backend side


.. code-block:: python

from time import time
## If you want write async tornado code import it
# from from wsrpc import WebSocketRoute, WebSocket, wsrpc_static
## else you should use thread-base handler
from wsrpc import WebSocketRoute, WebSocketThreaded as WebSocket, wsrpc_static

tornado.web.Application((
# js static files will available as "/js/wsrpc.min.js".
wsrpc_static(r'/js/(.*)'),
# WebSocket handler. Client will connect here.
(r"/ws/", WebSocket),
# Serve other static files
(r'/(.*)', tornado.web.StaticFileHandler, {
'path': os.path.join(project_root, 'static'),
'default_filename': 'index.html'
}),
))

# This class should be call by client.
# Connection object will be have the instance of this class when will call route-alias.
class TestRoute(WebSocketRoute):
# This method will be executed when client will call route-alias first time.
def init(self, **kwargs):
# the python __init__ must be return "self". This method might return anything.
return kwargs

def getEpoch(self):
# this method named by camelCase because the client can call it.
return time()

# stateful request
# this is the route alias TestRoute as "test1"
WebSocket.ROUTES['test1'] = TestRoute

# stateless request
WebSocket.ROUTES['test2'] = lambda *a, **kw: True

# initialize ThreadPool. Needed when using WebSocketThreaded.
WebSocket.init_pool()



Add the frontend side


.. code-block:: HTML

<script type="text/javascript" src="/js/q.min.js"></script>
<script type="text/javascript" src="/js/wsrpc.min.js"></script>
<script>
var url = window.location.protocol==="https:"?"wss://":"ws://" + window.location.host + '/ws/';
RPC = WSRPC(url, 5000);
RPC.addRoute('test', function (data) { return "Test called"; });
RPC.connect();

RPC.call('test1.getEpoch').then(function (data) {
console.log(data);
}, function (error) {
alert(error);
}).done();

RPC.call('test2').then(function (data) { console.log(data); }).done();
</script>

Reverse call from Server to Client
----------------------------------
backend:

.. code-block:: python

def do_notify(self):
awesome = 'Notification for you!'
yield self.socket.call('notify', result=awesome)

frontend:

.. code-block:: HTML

<script>
var url = (window.location.protocol==="https:"?"wss://":"ws://") + window.location.host + '/ws/';
RPC = WSRPC(url, 5000);
RPC.addRoute('notify', function (data) { return data.result; });
RPC.connect();
</script>
