Head-to-Head: NestJS vs Fastify vs Koa Analysis
@nestjs/core
@nestjs/core is the core module of the NestJS framework, a progressive Node.js framework for building efficient, reliable, and scalable server-side applications. It provides a solid architectural design based on TypeScript and decorators, allowing developers to easily create modular and maintainable code. NestJS leverages the power of Express.js under the hood while adding additional features like dependency injection, middleware, and decorators for routing.
Compared to traditional Node.js frameworks, NestJS offers a more structured and opinionated approach to building applications, making it suitable for large-scale projects. It promotes best practices like dependency injection and modular design, enhancing code reusability and testability.

fastify
Fastify is a high-performance web framework for Node.js focused on speed and low overhead. It is designed to be highly efficient and lightweight, making it ideal for building fast and scalable web applications. Fastify boasts a low latency and high throughput, achieved through its use of a powerful plugin architecture and a schema-based approach for request validation. It also provides built-in support for features like logging, error handling, and serialization.
Compared to other popular Node.js frameworks like Express, Fastify offers better performance and lower memory consumption. It is actively maintained with regular updates and a growing community of contributors, making it a reliable choice for building modern web applications.

koa
Koa is a lightweight and expressive Node.js web framework designed by the creators of Express. It uses modern JavaScript features like async/await to streamline middleware composition and improve error handling. Koa's minimalistic design allows developers to build efficient and scalable web applications with a focus on simplicity and modularity. It provides a robust set of methods for handling requests, responses, and middleware functions.
Compared to Express, Koa offers a more elegant and concise syntax, making it easier to write clean and maintainable code. Koa is actively maintained and continues to evolve, offering a modern alternative for building web servers and APIs in Node.js.
