What are the differences between popular Node.js frameworks?

What are the main differences between Express, Koa, and NestJS?

Express is minimal and flexible, Koa is more modern and lightweight, while NestJS is built for scalable applications with TypeScript support.

Which framework is better for building REST APIs?

Express is often preferred for REST APIs due to its simplicity and large ecosystem, but Koa can also be a great choice for more control.

What about performance? Is Koa faster than Express?

Yes, Koa is generally faster than Express because it uses async/await and has a smaller footprint, but the difference may not be significant for most applications.

Can you give me an example of a project where NestJS would be ideal?

NestJS is ideal for large-scale enterprise applications where maintainability and scalability are crucial, such as a microservices architecture.
