tornadose 0.4.1

Tornado-sent events

An implementation of the publish/subscribe pattern for the Tornado web server.

Installation

Tornadose is on PyPI:

$ pip install tornadose

This will grab the latest official release. Alternatively, or for development, you can clone the repository and install it manually:

$ git clone https://github.com/mivade/tornadose.git
$ cd tornadose
$ pip install -e .

Usage

A simple example of using server-sent events (a.k.a. EventSource):

import random
from tornado.ioloop import IOLoop, PeriodicCallback
from tornado.web import Application
from tornadose.handlers import EventSource
from tornadose.stores import DataStore

store = DataStore()

app = Application(
    [(r'/', EventSource, {'store': store})],
    debug=True)
app.listen(9000)

loop = IOLoop.instance()
PeriodicCallback(lambda: store.submit(random.random()), 1000).start()
loop.start()

To monitor the stream with curl:

$ curl http://localhost:9000

or with HTTPie:

$ http -S get localhost:9000

Additional demos can be found in the demos directory.
