Framework

NestJS is a progressive framework built on top of Node.js and written in TypeScript, making it a powerful tool for server-side application development. Its modular architecture and built-in support for dependency injection greatly simplify the development process.

Next.js has consistently paved the way for building performant and scalable web applications with React. As a framework, it addresses the multitude of challenges developers face in the modern web landscape. With its flexible file-system routing, server-side rendering, static site generation, and now, incremental static regeneration, Next.js has proven to be a boon for developers striving for a seamless development experience and optimized end-user performance.

Layouts are powerful in managing state across navigation transitions which is vital in single-page applications that need to maintain state without a full page reload. They can also be nested within each other, offering a flexible way to organize the UI hierarchy.
