$
$ # Set up the DEBUG environment

Note: To use the app, please access the registration page and create a new user. After authentication, the app will unlock the private pages.


Codebase structure

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

Simplified version

< PROJECT ROOT >
   |
   |-- app/                      # Implements app logic
   |    |-- base/                # Base Blueprint - handles the authentication
   |    |-- home/                # Home Blueprint - serve UI Kit pages
   |    |
   |   __init__.py               # Initialize the app
   |
   |-- requirements.txt          # Development modules - SQLite storage
   |-- requirements-mysql.txt    # Production modules  - Mysql DMBS
   |-- requirements-pqsql.txt    # Production modules  - PostgreSql DMBS
   |
   |-- .env                      # Inject Configuration via Environment
   |-- config.py                 # Set up the app
   |-- run.py                    # Start the app - WSGI gateway
   |
   |-- ************************************************************************

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

App / Base Blueprint

The Base blueprint handles the authentication (routes and forms) and assets management. The structure is presented below:

< PROJECT ROOT >
   |
   |-- app/
   |    |-- home/                                # Home Blueprint - serve app pages (private area)
   |    |-- base/                                # Base Blueprint - handles the authentication
   |         |-- static/
   |         |    |-- <css, JS, images>          # CSS files, Javascripts files
   |         |
   |         |-- templates/                      # Templates used to render pages
   |              |
   |              |-- includes/                  #
   |              |    |-- navigation.html       # Top menu component
   |              |    |-- sidebar.html          # Sidebar component
   |              |    |-- footer.html           # App Footer
   |              |    |-- scripts.html          # Scripts common to all pages
   |              |
   |              |-- layouts/                   # Master pages
   |              |    |-- base-fullscreen.html  # Used by Authentication pages
   |              |    |-- base.html             # Used by common pages
   |              |
   |              |-- accounts/                  # Authentication pages
   |                   |-- login.html            # Login page
   |                   |-- register.html         # Registration page
   |
   |-- requirements.txt                          # Development modules - SQLite storage
   |-- requirements-mysql.txt                    # Production modules  - Mysql DMBS
   |-- requirements-pqsql.txt                    # Production modules  - PostgreSql DMBS
   |
   |-- .env                                      # Inject Configuration via Environment
   |-- config.py                                 # Set up the app
   |-- run.py                                    # Start the app - WSGI gateway
   |
   |-- ************************************************************************

App / Home Blueprint

The Home blueprint handles UI Kit pages for authenticated users. This is the private zone of the app - the structure is presented below:

< PROJECT ROOT >
   |
   |-- app/
   |    |-- base/                     # Base Blueprint - handles the authentication
   |    |-- home/                     # Home Blueprint - serve app pages (private area)
   |         |
   |         |-- templates/           # UI Kit Pages
   |              |
   |              |-- index.html      # Default page
   |              |-- page-404.html   # Error 404 - mandatory page
   |              |-- page-500.html   # Error 500 - mandatory page
   |              |-- page-403.html   # Error 403 - mandatory page
   |              |-- *.html          # All other HTML pages
   |
   |-- requirements.txt               # Development modules - SQLite storage
   |-- requirements-mysql.txt         # Production modules  - Mysql DMBS
   |-- requirements-pqsql.txt         # Production modules  - PostgreSql DMBS
   |
   |-- .env                           # Inject Configuration via Environment
   |-- config.py                      # Set up the app
   |-- run.py                         # Start the app - WSGI gateway
   |
   |-- ************************************************************************

Deployment

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


Docker execution


The application can be easily executed in a docker container. The steps:

Get the code

$ git clone https://github.com/app-generator/flask-black-dashboard.git
$ cd flask-black-dashboard

Start the app in Docker

$ sudo docker-compose pull && sudo docker-compose build && sudo docker-compose up -d

Visit http://localhost:5005 in your browser. The app should be up & running.



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-black-dashboard.git
$ cd flask-black-dashboard
$
$ # 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 '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 (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.

Install using pip

$ pip install waitress

Start the app using waitress-serve

$ waitress-serve --port=8001 run:app
Serving on http://localhost:8001

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