Flask Gentelella

Gentelella is a free to use Bootstrap admin template.

This project integrates Gentelella with Flask using:

• Blueprints for scalability.


• flask_login for the login system (passwords hashed with bcrypt).


• flask_migrate.

Flask-gentelella also comes with a robust CI/CD pipeline using:

• The Pytest framework for the test suite (see the tests folder).


• A PostgreSQL database (optional; see below for installation instructions).


• Travis CI (automated testing)


• Coverage to measure the code coverage of the tests.


• Selenium to test the application with headless chromium.


• A Dockerfile showing how to containerize the application with gunicorn, and a Docker image available on dockerhub, and integrated to the CI/CD pipeline (see instructions below).


• A docker-compose file to start Flask-gentelella with nginx, gunicorn and a PostgreSQL database.

Here is an example of a real project implemented using Flask-Gentelella:

• Online demo


• Source code

This project shows:

• how back-end and front-end can interact responsively with AJAX requests.


• how to implement a graph model with SQLAlchemy and use D3.js for graph visualization.


• how to implement a workflow automation system using Vis.js.


• how to use Leaflet.js and WebGL-Earth for 2D and 3D GIS programming.


• how to use Flask APScheduler to implement crontab-like features.
