Controversies and Debates

While “Sliver Vanne” generally presents a balanced view of Python web development, it may spark some debates within the community:

  1. Framework preferences: The book’s coverage of multiple frameworks (Flask, Django, FastAPI) is comprehensive, but some developers might argue for more or less emphasis on particular frameworks based on their personal preferences or industry trends.

  2. ORM usage: The book’s strong focus on ORMs, while practical, might be contested by developers who prefer raw SQL for performance reasons or greater control over database operations.

  3. Monolithic vs. microservices: While the book covers both approaches, the balance between traditional monolithic applications and microservices architectures might be debated, especially given the industry’s ongoing shift towards the latter.

  4. Asyncio adoption: The book’s coverage of asynchronous programming with asyncio, while forward-thinking, might be seen as premature or unnecessary by developers working on smaller-scale applications.
