This article presents a simple Flask starter built on top of Pixel UI Kit - a free & open-source design system compliant with the latest UI design accessibility standards. The UI Kit passes with a green light some well-known evaluation tools like WAVE checker and Achecker - please click the links to see the reports.

The web app is coded with a super simple code-base enhanced with authentication, SQLite database, SQLAlchemy ORM to manipulate the database with ease and a super clean and nice UI.
To build the app, we need a basic tool-chain installed:
- Python3 - the programming language used to code the app
- Git - used to clone the source code from the Github repository. Using GIT is optional, we can download the sources in a ZIP archive from the public repository.
Build from sources
In case you like the design and decide to build the app, a few commands typed in the terminal is enough to see this beautiful app running in the browser:
Clone the source code from Github
$ git clone https://github.com/app-generator/flask-pixel-bootstrap-uikit.git $ cd flask-pixel-bootstrap-uikit
Install dependencies using a Virtual Environment
$ # Virtualenv modules installation (Unix based systems) $ virtualenv env $ source env/bin/activate $ $ # Virtualenv modules installation (Windows based systems) $ # virtualenv env $ # .\env\Scripts\activate $ $ # Install requirements $ pip3 install -r requirements.txt
Set up the env and start the app
$ # 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" $ flask run --host=0.0.0.0 --port=5000 $ $ # Access the app 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.

The Flask code-base is quite simple (no blueprints), coded like this intentionally for beginners. The app can be easily extended with other useful features.
