Server Side Events (SSE) client for Python

A Python client for SSE event sources that seamlessly integrates with urllib3 and requests.

Installation

$ pip install sseclient-py

Usage

import sseclient

def with_urllib3(url):
    """Get a streaming response for the given event feed using urllib3."""
    import urllib3
    http = urllib3.PoolManager()
    res = http.request('GET', url, preload_content=False)
    yield from sseclient.SSEClient(res).events()

def with_requests(url):
    """Get a streaming response for the given event feed using requests."""
    import requests
    res = requests.get(url, stream=True)
    yield from sseclient.SSEClient(res).events()

def with_httpx(url):
    """Get a streaming response for the given event feed using httpx."""
    import httpx
    with httpx.stream('GET', url) as s:
        # Note: 'yield from' is Python >= 3.3. Use for/yield instead if you
        # are using an earlier version.
        yield from sseclient.SSEClient(s.iter_bytes()).events()
