AdminLTE Jinja/Flask

Open-source Flask/Jinja Template generated by the AppSeed platform on top of AdminLTE, the famous dashboard template. For newcomers, Jinja is a template language used by frameworks like Flask, Bottle and Django to render HTML files in a secure, smart way. AdminLTE Jinja Template is basically a super simple Flask codebase without database, or other hard dependencies. Project might be used to code a future Flask project on top or integrate the design into a legacy project.

Up-to-date dependencies: Flask 2.0.1
SCSS compilation via Gulp
UI Kit: AdminLTE by ColorLib
Render Engine: Flask / Jinja2
Deployment scripts: Docker, Gunicorn/Nginx, HEROKU
Support via Github (issues tracker) and Discord.

Recompile CSS

To recompile SCSS files, follow this setup:

Step #1 - Install tools

NodeJS 12.x or higher
Gulp - globally
- npm install -g gulp-cli
Yarn (optional)

Step #2 - Change the working directory to assets folder

$ cd app/static/assets

Step #3 - Install modules (this will create a classic node_modules directory)

$ npm install
// OR
$ yarn

Step #4 - Edit & Recompile SCSS files

$ gulp scss

The generated file is saved in static/assets/css directory.

Deployment

The project comes with a basic configuration for Docker, Gunicorn, and Waitress.

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.
