Flask Dashboard AdminKit

Open-source Flask Dashboard generated by AppSeed op top of a modern design. AdminKit is a professional package that comes with hundreds of UI components, forms, tables, charts, pages and icons - Built on top of Bootstrap 5.


Features

  • DBMS: SQLite, PostgreSQL (production)
  • DB Tools: SQLAlchemy ORM, Alembic (schema migrations)
  • Modular design with Blueprints, simple codebase
  • Session-Based authentication (via flask_login), Forms validation
  • Deployment scripts: Docker, Gunicorn / Nginx, Heroku
  • Support via Github and Discord.

Boierplate Code Flask Dashboard - Template project provided by AppSeed.


How to use it

$ # Get the code
$ git clone https://github.com/app-generator/flask-adminkit.git
$ cd flask-adminkit
$
$ # Virtualenv modules installation (Unix based systems)
$ virtualenv env
$ source env/bin/activate
$
$ # Virtualenv modules installation (Windows based systems)
$ # virtualenv env
$ # .\env\Scripts\activate
$
$ # Install modules - SQLite Database
$ pip3 install -r requirements.txt
$
$ # OR with PostgreSQL connector
$ # pip install -r requirements-pgsql.txt
$
$ # Set the FLASK_APP environment variable
$ (Unix/Mac) export FLASK_APP=run.py
$ (Windows) set FLASK_APP=run.py
$ (Powershell) $env:FLASK_APP = ".\run.py"
$
$ # Set up the DEBUG environment
$ # (Unix/Mac) export FLASK_ENV=development
$ # (Windows) set FLASK_ENV=development
$ # (Powershell) $env:FLASK_ENV = "development"
$
$ # Start the application (development mode)
$ # --host=0.0.0.0 - expose the app on all network interfaces (default 127.0.0.1)
$ # --port=5000    - specify the app port (default 5000)  
$ flask run --host=0.0.0.0 --port=5000
$
$ # Access the dashboard in browser: http://127.0.0.1:5000/

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


Code-base 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-adminkit.git
$ cd flask-adminkit

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.


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-adminkit.git
$ cd flask-adminkit
$
$ # 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.

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.
