Flongo

Description:

Flongo is a "template application" for the Python/Flask - MongoDB environment.
It also provides a simple user management system that serves the following API endpoints:

• / (it will redirect to /login or /index depending on the existence of the active user session)
• /signup
• /login and
• /index

There is also an auxiliary endpoint:

• /info

which is not actually a part of the project, but exists in order to provide additional info to the application users.

Once a user signs up and logs in, the session cookie is created and it is valid for 30 minutes

Usage:

Running

$ docker-compose up

command will pull images and build, create, start and link the container instances for the services defined in the docker-compose.yml file, resulting in flongo application running on:

http://0.0.0.0 (and/or http://0.0.0.0:80)

• docker-compose.yml defines three services that will get started and linked:
  • flongo (python:2.7.12 with the following dependencies: flask, pymongo, libsass)
  • nginx
  • mongo (mongo:3.3.10)

Data model specifics:

The application stores data in three collections:

• users
  • usernames and email addresses are unique
• sessions
  • the list of the most recent user sessions
• past_sessions
  • the list of the past user sessions

Additional elements:

The application uses:

• Gunicorn - application server
• Nginx - front end reverse proxy
• Jinja2 - templating engine and
• libsass - CSS preprocessor

Notes:
