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)
