Engine.IO server
Project description
python-engineio
===============
[](https://travis-ci.org/miguelgrinberg/python-engineio)
Python implementation of the [Engine.IO](https://github.com/Automattic/engine.io) realtime server.
Features
--------
- Fully compatible with the Javascript
[engine.io-client](https://github.com/Automattic/engine.io-client) library.
- Compatible with Python 2.7 and Python 3.3+.
- Based on [Eventlet](http://eventlet.net/), enabling large number of
clients even on modest hardware.
- Includes a WSGI middleware that integrates Engine.IO traffic with standard
WSGI applications.
- Uses an event-based architecture implemented with decorators that hides the
details of the protocol.
- Implements HTTP long-polling and WebSocket transports.
- Supports XHR2 and XHR browsers as clients.
- Supports text and binary messages.
- Supports gzip and deflate HTTP compression.
- Configurable CORS responses to avoid cross-origin problems with browsers.
Example
-------
The following application uses Flask to serve the HTML/Javascript to the
client:
import engineio
import eventlet
from flask import Flask, render_template
eio = engineio.Server()
app = Flask(__name__)
@app.route('/')
def index():
"""Serve the client-side application."""
return render_template('index.html')
@eio.on('connect')
def connect(sid, environ):
print("connect ", sid)
@eio.on('message')
def message(sid, data):
print("message ", data)
eio.send(sid, 'reply')
@eio.on('disconnect')
def disconnect(sid):
print('disconnect ', sid)
if __name__ == '__main__':
# wrap Flask application with engineio's middleware
app = engineio.Middleware(eio, app)
# deploy as an eventlet WSGI server
eventlet.wsgi.server(eventlet.listen(('', 8000)), app)
