Needed a way to give a Yeah, Nah response in a suitably dramatic, troll-worthy way.

It's built on Flask and uses the MIT license (so feel free to extend as you wish).

Running locally is as simple as:

$ export FLASK_APP=app.py
$ flask run
 * Running on http://127.0.0.1:5000/

Or use gunicorn and run gunicorn app:app to improve the performance of concurrent requests!

Calling:

GET http://<server>:<port>/

Results in:

Yeah, nah.

GET http://<server>:<port>/<thing>

Results in:

<thing> ? Yeah, nah.

So you might do

GET http://127.0.0.1/sandwich for lunch?/

And the service will say:

sandwich for lunch? Yeah, nah.
