FastAPI vs Express.js

The Python framework that makes you feel like a genius, until you realize you're just using type hints meets the minimalist node. Here's our take.

FastAPI

Nice Pick

The Python framework that makes you feel like a genius, until you realize you're just using type hints.

Pros

• Automatic OpenAPI documentation generation
• Built-in data validation with Pydantic
• Async support out of the box

Cons

• Dependency injection can get messy in large projects
• Steeper learning curve for beginners compared to Flask

Express.js

The minimalist Node.js framework that's so simple, you'll spend half your time reinventing the wheel.

Pros

• Lightweight and unopinionated, giving you full control over your stack
• Massive ecosystem of middleware for everything from auth to logging
• Easy to get started with minimal boilerplate

Cons

• Lacks built-in structure, leading to messy codebases without discipline
• Can become a dependency hell with too many third-party packages

The Verdict

Use FastAPI if: You want automatic openapi documentation generation and can live with dependency injection can get messy in large projects.

Use Express.js if: You prioritize lightweight and unopinionated, giving you full control over your stack over what FastAPI offers.

The Bottom Line

FastAPI wins

The Python framework that makes you feel like a genius, until you realize you're just using type hints.
