This is a Python client library for iterating over http Server Sent Event (SSE) streams (also known as EventSource, after the name of the Javascript interface inside browsers). The SSEClient class accepts a url on init, and is then an iterator over messages coming from the server.

Installation

Use pip:

pip install sseclient

Usage

from sseclient import SSEClient

messages = SSEClient('http://mysite.com/sse_stream/')
for msg in messages:
    do_something_useful(msg)

Each message object will have a ‘data’ attribute, as well as optional ‘event’, ‘id’, and ‘retry’ attributes.

Optional init parameters:

  • last_id: If provided, this parameter will be sent to the server to tell it to return only messages more recent than this ID.

  • retry: Number of milliseconds to wait after disconnects before attempting to reconnect. The server may change this by including a ‘retry’ line in a message. Retries are handled automatically by the SSEClient object.

You may also provide any additional keyword arguments supported by the Requests library, such as a ‘headers’ dict and a (username, password) tuple for ‘auth’.

Development

Install the library in editable mode:

pip install -e .

Install the test dependencies:

pip install pytest backports.unittest_mock

Run the tests with py.test:

(sseclient)vagrant sseclient $ py.test
===================== test session starts ======================
platform linux2 -- Python 2.7.6 -- py-1.4.30 -- pytest-2.7.2

collected 11 items

test_sseclient.py ...........

================== 11 passed in 0.19 seconds ===================

There are a couple TODO items in the code for getting the implementation completely in line with the finer points of the SSE spec.
