✨ Start the app in Docker

Step 1 - Download the code from the GH repository (using GIT)

$ # Get the code
$ git clone https://github.com/app-generator/boilerplate-code-flask.git
$ cd boilerplate-code-flask

Step 2 - Edit .env and set DEBUG=True. This will activate the SQLite persistance.

DEBUG=True

Step 3 - Start the APP in Docker

$ docker-compose up --build 

Visit http://localhost:5085 in your browser. The app should be up & running.

✨ Set up the MySql Database

Note: Make sure your Mysql server is properly installed and accessible.

Step 1 - Create the MySql Database to be used by the app

• Create a new MySql database
• Create a new user and assign full privilegies (read/write)

Step 2 - Edit the .env to match your MySql DB credentials. Make sure DB_ENGINE is set to mysql.

• DB_ENGINE : mysql
• DB_NAME : default value = appseed_db
• DB_HOST : default value = localhost
• DB_PORT : default value = 3306
• DB_USERNAME: default value = appseed_db_usr
• DB_PASS : default value = pass

Here is a sample:

# .env sample

DEBUG=False                   # False enables the MySql Persistence

DB_ENGINE=mysql               # Database Driver
DB_NAME=appseed_flask         # Database Name
DB_USERNAME=appseed_flask_usr # Database User
DB_PASS=STRONG_PASS_HERE      # Password 
DB_HOST=localhost             # Database HOST, default is localhost 
DB_PORT=3306                  # MySql port, default = 3306 

✨ How to use it

Download the code

$ # Get the code
$ git clone https://github.com/app-generator/boilerplate-code-flask.git
$ cd app-generator/boilerplate-code-flask

👉 Set Up for Unix, MacOS

Install modules via VENV

$ virtualenv env
$ source env/bin/activate
$ pip3 install -r requirements.txt

Set Up Flask Environment

$ export FLASK_APP=run.py
$ export FLASK_ENV=development

Start the app

$ flask run

At this point, the app runs at http://127.0.0.1:5000/.

👉 Set Up for Windows

Install modules via VENV (windows)

$ virtualenv env
$ .\env\Scripts\activate
$ pip3 install -r requirements.txt

Set Up Flask Environment

$ # CMD 
$ set FLASK_APP=run.py
$ set FLASK_ENV=development
$
$ # Powershell
$ $env:FLASK_APP = ".\run.py"
$ $env:FLASK_ENV = "development"

Start the app

$ flask run

At this point, the app runs at http://127.0.0.1:5000/.

👉 Create Users

By default, the app redirects guest users to authenticate. In order to access the private pages, follow this set up:

• Start the app via flask run
• Access the registration page and create a new user:
  • http://127.0.0.1:5000/register
• Access the sign in page and authenticate
  • http://127.0.0.1:5000/login

✨ Code-base structure

The project is coded using blueprints, app factory pattern, dual configuration profile (development and production) and an intuitive structure presented bellow:
