Code-base structure

The project is coded using blueprints, app factory pattern, dual configuration profile (development and production) and an intuitive structure presented bellow:

The bootstrap flow

run.py loads the .env file
Initialize the app using the specified profile: Debug or Production
- If env.DEBUG is set to True the SQLite storage is used
- If env.DEBUG is set to False the specified DB driver is used (MySql, PostgreSQL)
Call the app factory method create_app defined in app/init.py
Redirect the guest users to Login page
Unlock the pages served by home blueprint for authenticated users

Recompile CSS

To recompile SCSS files, follow this setup:

Step #1 - Install tools

NodeJS 12.x or higher
Gulp - globally
- npm install -g gulp-cli
Yarn (optional)

Step #2 - Change the working directory to assets folder

$ cd apps/static/assets

Step #3 - Install modules (this will create a classic node_modules directory)

$ npm install
// OR
$ yarn

Step #4 - Edit & Recompile SCSS files

$ gulp scss

The generated file is saved in static/assets/css directory.

Deployment

The app is provided with a basic configuration to be executed in Docker, Gunicorn, and Waitress.

Gunicorn

Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX.

Install using pip

$ pip install gunicorn

Start the app using gunicorn binary

$ gunicorn --bind 0.0.0.0:8001 run:app
Serving on http://localhost:8001

Visit http://localhost:8001 in your browser. The app should be up & running.

Waitress

Waitress (Gunicorn equivalent for Windows) is meant to be a production-quality pure-Python WSGI server with very acceptable performance. It has no dependencies except ones that live in the Python standard library.
