What is it?

A multi-series tutorial walking through the development of a task manager app, CRUD operations, and a cohesive UI design using the latest from Bootstrap and Material Design.

Key features in the lesson:

• Flask, a Python Microframework
• Bootstrap, a set of HTML and CSS tools
• SQLite, a self-contained, embedded SQL database engine
• Material Design, additional UI tools
• Conda for virtual environment and package management

Functionalities

• Setting up your Flask project
  • Managing Environments
  • Managing Dependencies
  • Planning the DB ahead of time
  • Setting up Git and GitHub
• Template Rendering
  • Understanding url_for
  • Understanding render_template
  • Understanding extends and block
  • Jinja2
• Assets Management
• Database
  • SQLite Introduction
  • CRUD (Create, Read, Update, Delete)
  • Executing SQL commands from Flask
• Log In / Log Out session(s)
  • Understanding session
  • Understanding before_request()
• UI and UX Design
  • Using Bootstrap 4
  • Using Material Design
  • Using flash for notifications
  • Dynamic background image rendering using send_file
• Miscellaneous
  • Decorators and wraps
  • Understanding redirect
  • Understanding g
  • Importing configuration and thinking about security

Why?

There are no shortage of good tutorials that on their own, does a tremendous job at introducing new programming languages and tools to the absolute beginner. However, my motivation at creating a multi-series tutorial with this project is two-fold:

1. Many tutorials online serves as introductory materials to Flask, and as such often falls short in the required depth to help the reader go beyond 'hello world' to a more intermediary phase of Flask app development.
2. A flask app in itself isn't going to be any pleasant to look at (nor any helpful except for the most simplest of use-cases: think API microservice!). This series tries to combine the "learning flask" experience with UI / UX considerations, database considerations and helping the reader grasp critical concepts in structuring a Python app: managing environments, dependencies, sessions etc.
