Development Server

Diva comes with a couple of simple shortcuts for running your application using the WSGIServer from the Python standalone library.

Assuming you have an Application subclass (see ApplicationArchitecture?), for example:

>>> from diva.core import Application
>>> class MyApp(Application):
...     pass

You can then run that application using the development server as follows, directly from the Python shell:

>>> import logging
>>> from diva.server import serve
>>> serve(MyApp(), log_level=logging.DEBUG)
[INFO] diva.server: Serving <__main__.MyApp object at 0x10f63f0> on 127.0.0.1:8080

Command-Line Interface

It's also simple to enable your application to be run from the command-line, as shown in the following script:

import os
from diva.core import Application
from diva.server import main

class MyApp(Application):
    pass

if __name__ == '__main__':
    main(app)

Now running that script will automatically launch a simple command-line interface complete with options:

$ python myapp.py --help
Usage: myapp.py [options]

Options:
  -h, --help            show this help message and exit
  -b HOST, --host=HOST  hostname or IP address to bind to (default 127.0.0.1)
  -p PORT, --port=PORT  port number to listen to (default 8080)
  -r, --auto-reload     automatically restart after code changes (default
                        True)
  -v, --verbose         print as much as possible
  -q, --quiet           print as little as possible
