Python/Flask Backend Infograph
As your development journey continues, it's time to go behind the scenes. Flask is a lightweight, flexible web framework for Python that makes it easy to build web applications and APIs. Unlike larger frameworks.
Python Flask and Backend
As you move deeper into web development, understanding backend development becomes essential. Flask is a lightweight web framework that allows you to build powerful backend applications in Python. It enables routing, templating, and integration with databases.
Crash Course
- Key files
- Minimal server
- JavaScript fetch
FE to BE
Define in a single Jupyter Notebook that contains a Python Flask minimal application that can respond to JavaScript cells that use fetch to post and get data. Included are outputs that show server running, inputs from user, and outputs from server.
Anatomy
- System files
- API files
- Model files
App Structure
Flask anatomy covers the essential components of a Flask application, including how to set up routes, handle requests, and serve responses. Understanding the structure of a Flask app is crucial for building efficient backend services.
API creation
- Create API routes
- Fetch data from frontend
- Manage server responses and JSON

Jinja UI
- Display backend data
- Create admin dashboards
- Improve accessibility for Admins
Interface for Admins
Backend UIs present data from your database or APIs in a visual format. These dashboards help developers and admins manage, monitor, and debug application content and behavior.
Why Flask and Backend Matter
Flask gives you the essentials to get started, allowing you to add only the backend features you need (it’s lightweight)—such as API request handling. It’s beginner-friendly, widely used in the industry, and perfect for learning how the backend of a website works. With Flask, you’ll quickly go from writing simple scripts to powering dynamic, data-driven web apps.
