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, Heroku, Gunicorn, and Waitress.

Heroku

Steps to deploy on Heroku

Create a FREE account on Heroku platform
Install the Heroku CLI that match your OS: Mac, Unix or Windows
Open a terminal window and authenticate via heroku login command
Clone the sources and push the project for LIVE deployment

$ # Clone the source code:
$ git clone https://github.com/app-generator/flask-dashboard-atlantis-dark.git
$ cd flask-dashboard-atlantis-dark
$
$ # Check Heroku CLI is installed
$ heroku -v
heroku/7.25.0 win32-x64 node-v12.13.0 # <-- All good
$
$ # Check Heroku CLI is installed
$ heroku login
$ # this commaond will open a browser window - click the login button (in browser)
$
$ # Create the Heroku project
$ heroku create
$
$ # Trigger the LIVE deploy
$ git push heroku master
$
$ # Open the LIVE app in browser
$ heroku open

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.
