Open-source dashboard generated by AppSeed in Flask Framework. Atlantis Lite (Dark Design) is a free bootstrap 4 admin dashboard that is beautifully and elegantly designed to display various metrics, numbers or data visualization.

This sample shows how to define a new blueprint and use it on top of an existing starter. Steps:
- Create a new directory for the blueprint with files:
- init.py - declare the Blueprint
- routes.py - the routing rules handled by the new Blueprint
- The route /list-html will serve a simple HTML
<!-- File Contents: <ROOT> / app / home / templates / list-index.html -->

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.pyloads the.envfile- 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_appdefined 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
