runwsgi is a simple WSGI development server with support for hot reloading, based upon wsgiref.
Run runwsgi with the filename or module name of your application:
# my_wsgi_app.py
def application(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/plain')])
return [b'Hello world']$ runwsgi --port 8080 my_wsgi_app.py
The HTTP port can also be specified using -p or left out, in which case port
8000 is used. You can use a virtualenv by running runwsgi with the Python from
inside the virtualenv.
runwsgi automatically reloads any modules imported from the application
directory (and subdirectories) when they are modified. Note that reloading is
done using the importlib.reload function, and its documented caveats apply to
runwsgi as well. Most notably this means that anything imported using the
from ... import ... syntax will not be redefined on reload, and the old
version will still be used.
