Engine.IO server
Project description
Python implementation of the Engine.IO realtime server.
Features
Fully compatible with the Javascript engine.io-client library, versions 1.5.0 and up.
Compatible with Python 2.7 and Python 3.3+.
Supports large number of clients even on modest hardware when used with an asynchronous server based on eventlet or gevent. For development and testing, any WSGI compliant multi-threaded server can be used.
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 the Eventlet asynchronous server, and includes a small Flask application that serves 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)
