✨ 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 app is provided with a basic configuration to be executed in Docker, Heroku, Gunicorn, and Waitress.

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/sample-flask-htmlx-mkit.git
$ cd sample-flask-htmlx-mkit
$
$ # 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.

sample-flask-htmlx-mkit's Issues

Runtime Error - While importing 'run', an ImportError was raised

On windows, the manual build leads to an import error. Steps to reproduce the problem:

• Clone the project
• Create VENV
• Install deps:
  • pip3 install -r requirements.txt
• Set up the env:
  • export FLASK_APP=run.py
  • export FLASK_ENV=development
• Start the app or the CLI
  • flask run
  • flask shell

Both commands bumps import error (full log):

$ flask run
 * Tip: There are .env or .flaskenv files present. Do "pip install python-dotenv" to use them.
 * Serving Flask app '.\\run.py' (lazy loading)
 * Environment: development
 * Debug mode: on
Usage: flask run [OPTIONS]
Try 'flask run --help' for help.
