Build from sources

👉 Step #1 - Clone sources (this repo)

$ git clone https://github.com/app-generator/sample-flask-bootstrap.git
$ cd sample-flask-bootstrap

👉 Step #2 - Create 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

👉 Step #3 - Install dependencies

$ # Install requirements
$ pip3 install -r requirements.txt

👉 Step #4 - Set Up Environment

$ # 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"

👉 Step #5 - Create Tables (SQLite persistance)

$ # Create tables
$ flask shell
$ >>> from app import db
$ >>> db.create_all()

👉 Step #6 - (optional) Enable DEBUG Environment (local development)

$ # Set up the DEBUG environment
$ # (Unix/Mac) export FLASK_ENV=development
$ # (Windows) set FLASK_ENV=development
$ # (Powershell) $env:FLASK_ENV = "development"

👉 Step #7 - Start the project

$ # Run the application
$ # --host=0.0.0.0 - expose the app on all network interfaces (default 127.0.0.1)
$ # --port=5000    - specify the app port (default 5000)  
$ flask run --host=0.0.0.0 --port=5000
$
$ # Access the app in browser: http://127.0.0.1:5000/

Code-base structure
