Using Flask with CherryPy to serve static files


Option 1 is high-level CherryPy

option_1 actually uses the entirety of the CherryPy web framework (which their documentation refers to as the APPLICATION layer) to mount your WSGI application - plugins, tools, etc. can be utilized fully. To serve static files with CherryPy you would want to change your commented out code to be something like this:

cherrypy.tree.mount(None, '/static', config={    '/': {        'tools.staticdir.on': True,        'tools.staticdir.dir': app.static_folder    },})

Option 2 is low-level CherryPy

option_2, on the other hand, simply makes use of CherryPy's WSGI server implementation (the CORE layer) to serve your Flask app - it does not use any of the more framework-like aspects of CherryPy. If you are fine with serving your static files through Flask's routing layer as well, you can even remove the WSGIPathInfoDispatcher middleware and directly mount app under the CherryPyWSGIServer. If you want CherryPy to manage the /static route serving then you will want to mount an instance of cherrypy.tools.staticdir.handler under the /static route, like so:

static_handler = tools.staticdir.handler(section='/', dir=app.static_folder)d = wsgiserver.WSGIPathInfoDispatcher({'/': app, '/static': static_handler})


If you want to replace the development server provided inside Werkzeug, I use the following in Flask-Script to replace runserver(). This will however in __main__

def runserver():    """    Overwriting the Flask Script runserver() default.    CherryPy is much more stable than the built-in Flask dev server    """    debug_app = DebuggedApplication(app, True)    cherrypy.tree.graft(debug_app, '/')    cherrypy.config.update({        'engine.autoreload_on': True,        'server.socket_port': 5000,        'server.socket_host': '0.0.0.0'    })    try:        cherrypy.engine.start()        cherrypy.engine.block()    except KeyboardInterrupt:        cherrypy.engine.stop()

If you do not have DebuggedApplication wrapper the DEBUG = True will not work. You may need to adjust this slightly based on your application. It will also provide Ctrl+C
