The flask package provides a micro-framework for making applications with web interfaces (a.k.a "web applications").

Run a flask application "in development" using a web server on your local machine, and/or "in production" using a remote web server hosted by a provider like Heroku. If you run it in development, you should be able to use it by visiting localhost:5000 in a browser, whereas if you run it in production, you should be able to use it by visiting the production server's URL.

Installation

First install flask, if necessary:

pip install flask

Usage

Follow the official tutorial.

• Products API (Flask) - just a JSON API with no front-end interface, uses CSV datastore.
• Salad System (Flask) - includes a front-end interface, and uses an SQL datastore, although it would be possible to use a CSV datastore instead.
