NestJS vs. Express.js: Which Node.js framework to choose?

Both NestJS and Express.js are popular Node.js frameworks, but they cater to different development needs. Express.js is a lightweight, flexible framework that provides a minimalist approach to building APIs and web applications, making it ideal for small to medium-sized projects. NestJS, on the other hand, is a full-featured framework built on top of Express, offering a modular architecture, TypeScript support, and dependency injection, making it perfect for large-scale applications.

If you need a simple, fast framework with minimal setup, go with Express.js. If you prefer structured, scalable development with built-in best practices, NestJS is the better choice.

Key Takeaways:

• Express.js → Best for quick API development and small projects.

• NestJS → Ideal for enterprise-level applications with TypeScript support.

• NestJS enforces a structured architecture, while Express.js is more flexible.
