Flask Tutorial

This tutorial is designed for developers starting from scratch to learn Flask, progressively guiding you to build web applications: from environment setup, routing and templates, requests and responses, to blueprint organization, configuration management, and production deployment.

• Target Audience: Backend/full-stack beginners, Python programmers, engineers who want to quickly deliver web solutions with lightweight solutions
• Prerequisites: Basic Python syntax knowledge, understanding of virtual environments and package management is helpful
• Version Range: Flask 2.x/3.x, Python 3.9+

Learning Path:

1. Introduction (Overview)
2. Environment Setup
3. Quickstart
4. App Structure
5. Routing
6. Request & Response
7. Templates
8. Static Files
9. Configuration
10. Blueprints (Modularization)

Recommendations:

• Develop and run entirely in virtual environments
• First follow examples to complete a minimal runnable version, then gradually refactor to factory pattern and blueprint structure
• Use debug mode during development, deploy with WSGI/ASGI servers in production

More Topics (will be provided gradually): Forms and validation, databases and migrations, authentication and authorization, sessions and cookies, testing and logging, REST APIs, deployment and extensions, best practices and security, etc.
