using Flask and Tornado together?

Question

I am a big fan of Flask - in part because it is simple and in part because has a lot of extensions. However, Flask is meant to be used in a WSGI environmen

Answer 1

Based on 1 and 2, the combined and shorter answer is

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":

    from tornado.wsgi import WSGIContainer
    from tornado.httpserver import HTTPServer
    from tornado.ioloop import IOLoop

    http_server = HTTPServer(WSGIContainer(app))
    http_server.listen(8000)
    IOLoop.instance().start()

Please consider the warning about performance that has been mentioned on 2 , 3

Answer 2

i think i got 50% of the solution, the cookies are not tested yet, but now i can load Flask application using Tornado, and mixing Tornado + Flask together :)

first here is flasky.py the file where the flask application is:

from flask import Flask
app = Flask(__name__)

@app.route('/flask')
def hello_world():
  return 'This comes from Flask ^_^'

and then the cyclone.py the file which will load the flask application and the tornado server + a simple tornado application, hope there is no module called "cyclone" ^_^

from tornado.wsgi import WSGIContainer
from tornado.ioloop import IOLoop
from tornado.web import FallbackHandler, RequestHandler, Application
from flasky import app

class MainHandler(RequestHandler):
  def get(self):
    self.write("This message comes from Tornado ^_^")

tr = WSGIContainer(app)

application = Application([
(r"/tornado", MainHandler),
(r".*", FallbackHandler, dict(fallback=tr)),
])

if __name__ == "__main__":
  application.listen(8000)
  IOLoop.instance().start()

hope this will help someone that wants to mix them :)
