Introduction to Nest.js

“

Hello everyone, and welcome to this amazing course of NestJS. Before we start with the course, let me give you a quick introduction about the NestJS framework. NestJS is first of all a very powerful NodeJS framework, which is used for building robust and scalable server side applications. At its core, NestJS uses TypeScript, and it is one of the main reasons why this framework is preferred more. Because with TypeScript, we can have a strong and statically typed foundation in the projects. By default, the NestJS builds upon ExpressJS. That is, it is integrated with ExpressJS, which means it follows and offers the same concepts and functionalities that come with ExpressJS. Though it is still flexible with other foundations like Fastify or GraphQL etc. to facilitate rapid development and provide readable and meaningful code. So implementing REST APIs or GraphQL APIs are very easy with NestJS. Along with this, NestJS also follows a modular architecture inspired by Angular, making it easy to organize your code into manageable and reusable components. So features like dependency injection and loose coupling, and many more features which help a lot in building and maintaining a full-stack web application. That's right, we can easily build and maintain complex, full-stack web applications with NestJS as it uses a model view controller pattern just like any other frameworks like Laravel or Ruby on Rails. It contains tons of built-in modules to work with database and handle security seamlessly and many other things which we usually implement in server-side applications. So being just a framework, it offers a lot of useful functionalities. We can think of it as Node.js but with superpowers. So buckle up and let's dive into this section and see what NestJS has to offer.
