Nest.js is a progressive Node.js framework for building efficient, scalable, and maintainable server-side applications. It uses TypeScript by default (while supporting JavaScript) and is built on top of Express.js, with support for other frameworks like Fastify. Nest.js adopts a modular architecture inspired by Angular, making it easy to organize and manage code in large-scale applications. Learning Nest.js is important for aspiring web developers because it combines the power of Node.js with a structured framework, enabling them to build robust APIs, microservices, and full-stack applications while adhering to best practices.
A tutor can accelerate this process by offering structured lessons on Nest.js's modular design, decorators, dependency injection, and testing practices, as well as guiding learners through hands-on projects that demonstrate how to develop production-ready backend systems with Nest.js.
