WSRPC WebSocket RPC for tornado

Project description

Remote Procedure call through WebSocket between browser and tornado.

Installation

Install via pip:

pip install wsrpc-tornado

Simple usage

Add the backend side:

from time import time
from wsrpc import WebSocketRoute, WebSocketThreaded as WebSocket, wsrpc_static

tornado.web.Application((
    wsrpc_static(r'/js/(.*)'),
    (r"/ws/", WebSocket),
    (r'/(.*)', tornado.web.StaticFileHandler, {
         'path': os.path.join(project_root, 'static'),
         'default_filename': 'index.html'
    }),
))

class TestRoute(WebSocketRoute):
    def init(self, **kwargs):
        return kwargs

    def getEpoch(self):
        return time()

# stateful request
WebSocket.ROUTES['test1'] = TestRoute

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

# initialize ThreadPool
WebSocket.init_pool()

Add the frontend side:

<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>
